Pre-and Post-Prostatectomy Detrusor Wall Thickness and the Symptom Profile in Patients with Benign Prostatic Enlargement: A Prospective Review.

INTRODUCTION: The urinary bladder undergoes morphological and functional changes in patients with symptomatic benign prostatic enlargement (BPE). These detrusor changes reflect chronically increased intravesical pressure as a result of outlet obstruction. This study aims to determine the relationship between the Pre- and Post-op detrusor wall thickness (DWT), international prostate symptom score (IPSS), and duration of lower urinary tract symptoms (LUTS) in patients who had open simple prostatectomy (OSP). METHOD: This was a prospective study of a cohort of patients who had OSP for symptomatic BPE. The IPSS and symptom duration for each patient were noted. Each patient also had an abdominal ultrasound scan with a measurement of their DWT. Retropubic OSP was done for each patient. The detrusor wall thickness was also measured 12 weeks after the prostatectomy. RESULTS: Fifty-two patients completed the study; the mean age was 66.37 ± 8.09 years. The median pre-operative IPSS was 28 (IQR = 13.75), and the median duration of symptoms was 24 months (IQR = 37 months). The mean pre-operative DWT was 4.41 ± 1.38mm, while the mean post-operative DWT was 2.16 ± 0.98mm. The preoperative IPSS (p = 0.833) and duration of symptoms (p = 0.375) did not significantly correlate with the pre-operative DWT. There was a significant reduction in the mean DWT (p < 0.001) and IPSS (p < 0.001) following prostatectomy. CONCLUSION: DWT appears not to be significantly influenced by the severity or duration of LUTS. However, it reduced significantly following OSP with corresponding improvement in urinary symptoms.

INTRODUCTION: La vessie subit des changements morphologiques et fonctionnels chez les patients présentant une hyperplasie bénigne de la prostate (HBP) symptomatique. Ces modifications du détrusor reflètent une pression intravésicale chroniquement augmentée en raison de l'obstruction de la sortie. Cette étude vise à déterminer la relation entre l'épaisseur de la paroi du détrusor (EPD) avant et après l'opération, le score international des symptômes prostatiques (IPSS) et la durée des symptômes des voies urinaires inférieures (LUTS) chez les patients ayant subi une prostatectomie simple ouverte (OSP). MÉTHODE: Il s'agissait d'une étude prospective d'une cohorte de patients ayant subi une OSP pour une HBP symptomatique. L'IPSS et la durée des symptômes pour chaque patient ont été notés. Chaque patient a également subi une échographie abdominale avec mesure de leur EPD. Une OSP rétropubienne a été réalisée pour chaque patient. L'épaisseur de la paroi du détrusor a également été mesurée 12 semaines après la prostatectomie. RÉSULTATS: Cinquante-deux patients ont terminé l'étude ; l'âge moyen était de 66,37 ± 8,09 ans. L'IPSS médian préopératoire était de 28 (IQR = 13,75), et la durée médiane des symptômes était de 24 mois (IQR = 37 mois). L'EPD moyenne préopératoire était de 4,41 ± 1,38 mm, tandis que l'EPD moyenne postopératoire était de 2,16 ± 0,98 mm. L'IPSS préopératoire (p = 0,833) et la durée des symptômes (p = 0,375) n'ont pas significativement corrélé avec l'EPD préopératoire. Il y a eu une réduction significative de l'EPD moyenne (p < 0,001) et de l'IPSS (p < 0,001) après la prostatectomie. CONCLUSION: L'EPD ne semble pas être significativement influencée par la gravité ou la durée des LUTS. Cependant, elle a considérablement diminué après l'OSP avec une amélioration correspondante des symptômes urinaires. MOTS-CLÉS: Hyperplasie bénigne de la prostate, Épaisseur de la paroi du détrusor, Score international des symptômes prostatiques, Prostatectomie simple ouverte.

Effect of Perioperative Tranexamic Acid on Blood Loss following Open Simple Prostatectomy: A Prospective Review in Nigerian Men.

BACKGROUND: Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement. METHODOLOGY: This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented. RESULTS: Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups. CONCLUSION: The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.

CONTEXTE: L'hémorragie est une complication courante après une prostatectomie simple ouverte et les patients doivent parfois recevoir une transfusion sanguine. Il a été démontré que l'acide tranexamique réduit la perte de sang après une résection transurétrale de la prostate et une prostatectomie radicale ouverte. Cette étude a évalué l'effet de l'administration intraveineuse périopératoire d'acide tranexamique sur les pertes sanguines et les taux de transfusion sanguine chez des patients ayant subi une PSO pour hypertrophie bénigne de la prostate. MÉTHODOLOGIE: Il s'agissait d'une étude comparative de patients dont la prostate de 60 g et plus était documentée et qui devaient subir une PSO. L'hématocrite de base a été effectué un jour avant la chirurgie. Les patients ont été répartis aléatoirement dans le groupe acide tranexamique, qui a reçu de l'acide tranexamique periopératoire par voie intraveineuse, et dans le groupe sans TXA, qui a reçu un placebo. Tous les patients ont subi une prostatectomie rétropubienne simple ouverte. L'hématocrite postopératoire a été évalué, et la perte de sang calculée à l'aide de la formule de Gross modifiée. Le taux de transfusion a été documenté. RÉSULTATS: Cinquante-six patients ont participé à cette étude et ont été randomisés entre le groupe avec acide tranexamique et le groupe sans acide tranexamique. L'âge moyen des patients du groupe acide tranexamique était de 66,07 ±7,08 ans et était comparable à celui du groupe sans acide tranexamique qui était de 66,50 ± 8,80 ans (P =0,842). La perte sanguine totale médiane était plus faible dans le groupe avec acide tranexamique (502 ml, IQR 613) que dans le groupe sans acide tranexamique (801 ml, IQR 1069). La différence de la perte de sang médiane entre les deux groupes était de 299 ml (U 275, P 0,055). Le taux de transfusion sanguine était inférieur dans le groupe acide tranexamique (6 patients, 21%) par rapport au groupe sans acide tranexamique (11 patients, 39%), (P =0,146). Il n'y avait pas de différence dans les taux de complication entre les deux groupes. CONCLUSION: L'utilisation de l'acide tranexamique chez les patients subissant une prostatectomie simple ouverte a montré une tendance à la réduction de la perte de sang peropératoire et un besoin moindre de transfusion sanguine.

Simple Prostatectomy for Giant Benign Prostatic Hyperplasia in Sub-Saharan Africa: Case Series and Literature Review.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a common cause of bladder outlet obstruction in men worldwide. African men are known to have larger mean prostate volumes than other races. Giant benign prostatic hyperplasia (GBPH) is defined as prostate size greater than 200 grams. Management of GBPH is associated with several challenges which have been under-reported from the African sub-region. OBJECTIVE: To highlight the peculiarities of clinical presentation, surgical management and outcome of GBPH. PATIENTS AND METHODS: Men with BPH and trans-rectal ultrasound estimated prostate volume > 200 grams who were scheduled for open simple prostatectomy between January and December 2016 in our hospital were prospectively studied. RESULTS: Four patients with GBPH had simple prostatectomy during the period under review. Their ages ranged from 68 to 78 years with a mean age of 73.7 years.Three patients (75.0%) had transvesical prostatectomy while one (25.0%) had retropubic prostatectomy. The enucleated prostate specimen were found to weigh 312.1g, 396.4g, 420.8g and 450.0g respectively with mean weight of 394.8 ±50.2g and mean operation time of 111.7 ±19.7 minutes. They all had blood transfusion post-operatively with mean transfusion of 3±1.5 pints of blood per patient with relatively longer hospital stay (mean 10 days). CONCLUSION: The surgical management of GBPH can be quite challenging. Recalcitrant gross haematuria, chronic urinary retention and renal impairment are possible modes of presentation. Open simple prostatectomy is the best option for treatment in our environment. It is associated with improved quality of life and minimal morbidity in expert hands.

INTRODUCTION: L'hyperplasie bénigne de la prostate (HBP) est une cause fréquente d'obstruction de la vessie chez les hommes du monde entier. Les hommes africains sont connus pour avoir des volumes de prostate moyens plus importants que les autres races. L'hyperplasie bénigne géante de la prostate (GBPH) est définie comme une taille de la prostate supérieure à 200 grammes. La gestion du GBPH est associée à plusieurs défis qui ont été sous-déclarés dans la sous-région africaine. OBJECTIF: Mettre en évidence les particularités de la présentation clinique, de la prise en charge chirurgicale et du résultat de la GBPH. PATIENTS ET MÉTHODES: Les hommes atteints d'HBP et d'une échographie trans-rectale d'un volume prostatique estimé> 200 grammes qui devaient subir une prostatectomie simple ouverte entre janvier et décembre 2016 dans notre hôpital ont été étudiés de manière prospective. RÉSULTATS: Quatre patients atteints de GBPH ont eu une prostatectomie simple au cours de la période sous revue. Leur âge variait de 68 à 78 ans avec un âge moyen de 73,7 ans). Trois patients (75,0%) ont eu une prostatectomie transvésicale et un (25,0%) une prostatectomie rétropubienne. L'échantillon de prostate énucléé pesait respectivement 312,1 g, 396,4 g, 420,8 g et 450,0 g avec un poids moyen de 394,8 ± 50,2 g et une durée opératoire moyenne de 111,7 ±19,7 minutes. Ils ont tous eu une transfusion sanguine postopératoire avec une transfusion moyenne de 3 ± 1,5 pintes de sang par patient avec un séjour à l'hôpital relativement plus long (10 jours en moyenne). CONCLUSION: La prise en charge chirurgicale de la GBPH peut être assez difficile. Une hématurie macroscopique récalcitrante, une rétention urinaire chronique et une insuffisance rénale sont des modes de présentation possibles. La prostatectomie simple ouverte est la meilleure option de traitement dans notre environnement. Elle est associée à une meilleure qualité de vie et à une morbidité minimale entre des mains expertes. MOTS CLÉS: Hyperplasie bénigne géante de la prostate, prostatectomie simple, Afrique subsaharienne.

Variations of renal vascular anatomy in a nigerian population: A computerized tomography studys.

BACKGROUND: A broad spectrum of renal vascular variations has been reported by anatomists and radiologists. The prevalence of these variations is extremely divergent in different populations. Therefore, radiologists and surgeons in different climes must be knowledgeable about the type and prevalence of the variants in their area of practice to avoid diagnostic pitfalls and for optimization of surgical techniques. OBJECTIVE: The objective of this study is to describe the types and prevalence of renal vascular variations among patients undergoing contrast-enhanced computerized tomography (CECT) of the abdomen in a Nigerian population, as well as provide a concise review of literature on the embryological basis and clinical significance of the identified variations. MATERIALS AND METHODS: This study was a retrospective review of 200 CECT of the abdomen to identify variations of arterial (accessory, early branching, and precaval) and venous (multiple, retroaortic, and circumaortic) anatomy of the kidneys. RESULTS: We studied 200 patients, 102 (51%) females and 98 (49%) males. Age range is 18-90 years (mean = 53.08 ± 17.01). Prevalence of any renal vascular variations was 50%, arterial variations were 37%, and venous variations were 13%. Variations were significantly more common in males, P = 0.000075. The most common arterial variant was the accessory renal artery (23%) seen in 10% (right) and 13.0% (left); early branching was seen in 4.0% (right) and 0.5% (left) as well as precaval right renal artery seen in 4.5%. Venous variants were late confluence 3.0% (right) and 2.5% (left); multiple veins was seen in 2.5% (right) and 2.5% (left) as well as retroaortic left renal vein seen in 2.0%. The inferior polar accessory artery was the most prevalent accessory artery. Early arterial bifurcation was significantly more common on the right (P = 0.016) while other vascular variants showed no statistically significant association with laterality. CONCLUSION: Variation of renal vascular anatomy is a frequent finding among Nigerians. Radiologists and surgeons must be aware of these variants for optimization of surgical techniques.

Thermaland non-thermal pasteurization of citrus fruits: A bibliometrics analysis.

Thermal and non-thermal pasteurization (TNP) process of food is not new to food technology, disparities in the merits and demerits of the two pasteurizations necessitate their uses concurrently. Bibliometric analysis of the subject matter is expedient to analyses of database for published publications. Especially to provide times, state-of-the art innovations and prospects of the techniques. In addressing these lacunas, we utilized VOSview visualization to establish connections among crucial elements within a dataset of 495 research publications gathered from Web of Science. This approach facilitated the identification of links and collaboration networks among key factors in the research landscape. Analysis of publications indicate thermal pasteurization is an age long practices, while non-thermal pasteurization is gaining more acceptance. This study exposed ranking differences in scholar's collaboration, citations of scholars, impactful institution and most published countries. United State, China, United Kingdom have largest publications of research in TNP among the top 10 countries. Coupling network and Sankey illustration showed new area of research where new researchers and scholars can begin new phase of findings.

Benign prostate hyperplasia: average volume in southwestern Nigerians and correlation with anthropometrics.

OBJECTIVES: To determine the prevalent age of symptomatic benign prostate hyperplasia (BPH), the average BPH volume, and the association between BPH volumes and the age, and anthropometrics in our immediate black community. PATIENTS, MATERIALS AND METHOD: Selected patients with lower urinary tract symptoms (LUTS) due to BPH with tissue diagnosis, and adult men of similar age group with no irritative or obstructive LUTS were prospectively studied from July 2003 to June 2009. The age, height and weight were recorded, prostate volumes determined with ultrasound, body mass index (bmi) calculated, and correlations determined between the prostate volume and the age, and anthropometrics. RESULTS: 105 patients aged 43-88 yrs (mean=64.4, 8.88 SD) managed for BPH were studied with 93 asymptomatic men aged 43-80 yrs (mean=56.15, 9.89 SD). The mean (SD) prostate volume, height, weight and bmi were 83.8 (37.7) ml, 1.67 (0.07) m, 63.6 (9.32) kg and 22.8 (3.03) kg/m2, and 24.5 (9.2) ml, 1.69 (0.06) m, 68.9 (10.6) kg and 24.2 (3.44) kg/m2 respectively for symptomatic and asymptomatic groups. In the symptomatic group, BPH volume showed significant positive correlation with the age (p=0.030), but no correlation with the weight (p=0.550), height (p=0.375) and bmi (p=0.840). In the asymptomatic group, prostate volume also showed significant positive correlation with the age (p=0.041), but no correlation with the weight (p=0.434), height (p=0.394), and bmi (p=0.203). CONCLUSION: The prevalent age of symptomatic BPH in our community is 43- 88 years with 83.79 (37.66) ml mean (SD) volume in symptomatic patients and 24.45 (9.21) ml in asymptomatic men. BPH volume correlates with age but not with anthropometrics. Lack of correlation with BPH volume suggests that anthropometrics may not be risk factors for development of BPH in our community.

Testicular schistosomiasis: a case report.

AIMS AND OBJECTIVES: To report a case of testicular Schistosomiasis with a suspicion of testicular cancer. PATIENT AND METHODS: Hospital record of a 16 year old patient with histopathology confirmation of testicular Schistosomiasis was reviewed and summarised. The patient who had painless testicular nodules and ultrasound features of heterogenous echotexture and hypoechoic focus was diagnosed as testicular cancer and treated with radical orchidectomy. Histopathology confirmed testicular Schistosomiasis and the patient had additional praziquantel therapy. RESULTS: Patient was followed up for over 26months post-operative. CONCLUSIONS: Testicular Schistosomiasis can mimick malignant testicular tumour. Hard nodular testicular mass in a patient with recent past history of schistosomiasis should arouse suspicion of testicular Schistosomiasis. Awareness and early presentation will prevent unwarranted orchidectomy.

Benign prostate hyperplasia: average volume in southwestern Nigerians and correlation with anthropometrics.

AIMS AND OBJECTIVES: To determine the prevalent age of symptomatic benign prostate hyperplasia (BPH), the average BPH volume, and the association between BPH volumes and the age, and anthropometrics. PATIENTS, MATERIALS AND METHODS: Selected patients with lower urinary tract symptoms (LUTS) due to BPH with tissue diagnosis, and adult men of similar age group with no irritative or obstructive LUTS were prospectively studied from July 2003 to June 2009. The age, height and weight were recorded; prostate volumes determined with ultrasound, body mass index (BMI) calculated, and correlations determined between the prostate volume, the age and anthropometrics. RESULTS: One hundred and five patients aged 43-88years (mean=64.4, 8.88SD) managed for BPH were studied with 93 asymptomatic men aged 43-80years (mean=56.15, 9.89SD). The mean (SD) prostate volume, height, weight and BMI were 83.8(37.7) ml, 1.67(0.07) m, 63.6(9.32) kg and 22.8(3.03) kg/m2, and 24.5(9.2) ml, 1.69(0.06) m, 68.9(10.6) kg and 24.2(3.44) kg/m2 respectively for symptomatic and asymptomatic groups. In the symptomatic group, BPH volume showed significant positive correlation with the age (p=0.030), but no correlation with the weight (p=0.550), height (p=0.375) and BMI (p=0.840). In the asymptomatic group, prostate volume also showed significant positive correlation with the age (p=0.041), but no correlation with the weight (p=0.434), height (p= 0.394), and BMI (p=0.203). CONCLUSION: The prevalent age of symptomatic BPH in our community is 43-88years with 83.79(37.66) ml mean (SD) volume in symptomatic patients and 24.45(9.21) ml in asymptomatic men. BPH volume correlates with age but not with anthropometrics. Lack of correlation with BPH volume suggests that anthropometrics may not be risk factors for development of BPH.

Short hospital stay after appendicectomy.

AIMS AND OBJECTIVES: To determine the applicability of short hospital stay after appendicectomy in rural and semi-urban Nigerian community. PATIENTS AND METHODS: A 30-month prospective study on patients with uncomplicated acute appendicitis was carried out The age ranged from 5-70 years, mean of 28.7 years, there was almost even sex distribution between male and female. All the patients presented with clinical evidences of acute appendicitis. RESULTS: The operative findings were inflamed and oedematous appendix in about 80%, minimal exudates drained in only about 25% of the patients. Postoperative wound complications occurred in 1.3-5% of patients. All the postoperative complications were successfully managed in the outpatient clinic. 71.8% were discharged on the 2nd postoperative day, 20.5% on 3rd postoperative day, 4 (5%) on 4th postoperative day and 1(1.3%) each on 5th and 7th day. There was postoperative pain tolerance and late mobilisation in those who stayed for 3-4 days; moderately severe wound infection was responsible for those who stayed for 5th- 7th day. CONCLUSION: Short hospital stay after appendicectomy was possible in majority of patients with uncomplicated acute appendicitis. Minimal postoperative fluid therapy and antibiotic administration was adequate in well-selected cases.

HISTOMORPHOLOGICAL PATTERN OF UROLOGIC MALIGNANCIES IN ILE-IFE, SOUTH-WESTERN NIGERIA.

INTRODUCTION: The last decade witnessed a remarkable rise in the prevalence of several malignant diseases in Nigeria. Whether Urologic malignancies (UM) have followed the same trend remains to be studied. The pattern of UM diagnosed in a Nigerian tertiary hospital is hereby presented. Our aim was to determine the pattern and prevalence of histologically diagnosed UM in Obafemi Awolowo University Teaching Hospitals Complex. Ile-Ife, Nigeria. MATERIALS AND METHODS: A 10-year retrospective review of all patients diagnosed with UM was carried out between January 2005 and December 2014. Data was obtained from the patients' case files and the Ife-Ijesha Cancer registry. Information obtained included demographic characteristics, site of origin and histology. Data was analysed with Statistical package for Social sciences (SPSS) Version 20. RESULTS: A total of 4675 malignancies were histologically confirmed during the study period. UM accounted for 420 (8.9%) of total malignancies. Prostate cancer was the commonest UM with 315 (75%) cases. Others include renal tumours 62(14.8%), bladder tumours 29 (6.9%), testicular tumours 13(3.1%) and scrotal tumour 1(0.2%). UM were commoner in males (348, 88.8%) than females (47, 11.2%) and accounted for 13.8% and 2.18% of all tumours in males and females respectively. CONCLUSION: This study revealed a rising prevalence of UM most especially Prostate and Renal Cancers among other malignancies in Ile-Ife.

Laryngeal carcinoma: our experience at Obafemi Awolowo University Teaching Hospital complex, Ile-Ife, Nigeria.

OBJECTIVES: To determine the prevalent age, frequency, pattern ofpresentation, investigations and outcome of management of laryngeal carcinoma in our environment. DESIGN: 10 year retrospective study (January 1994 to December 2003). SETTING: Teaching hospital. SUBJECTS: 13 patients with tissue diagnosis managed for laryngeal carcinoma. MAIN OUTCOME MEASURES: The age, sex, occupation, presentation, use of cigarettes and alcohol, investigations, tissue diagnosis, outcome of management and duration of follow up were extracted from hospital records and analysed. RESULTS: The age of patients ranged 38 to 88 years (median 69, male: female ratio=12:1). The histopathology was squamous cell carcinoma in all. Common symptoms included hoarseness of voice and breathlessness in all the patients, cough and weight loss in seven patients and otalgia in six. Only one patient indulged in alcohol while two were regular cigarette smokers. All the patients presented in stage IV with respiratory distress necessitating emergency tracheostomy in all. Seven patients had total laryngectomy plus post-operative radiotherapy while two patients had pharyngo-laryngectomy, thyroidectomy and radical neck dissection plus post-operative radiotherapy and thyroxine supplement. Post operative complications included pharyngocutaneous fistula in two patients, pharyngeal stenosis, stoma stenosis, and hypocalcaemia with hypothyroidism in one patient each. The fistulae were management conservatively. Prognosis was good despite late presentation. CONCLUSION: Laryngeal carcinoma occurs predominantly in males. Presentation is late with hoarseness of voice and breathlessness in our community. Soft tissue neck X-ray is a useful diagnostic tool. Scarcity of radiotherapy centres, ignorance, local taboos, poverty and poor recognition by general medical practitioners negatively affected management of the patients. Laryngeal carcinoma should be excluded when managing elderly patients for bronchial asthma.

Adult nephrectomy: our experience at Ile-Ife.

OBJECTIVES: To determine indications for adult nephrectomy in our community and the outcome of the procedure in our Institution. MATERIALS AND METHOD: Records of adult patients scheduled for nephrectomy at Obafemi Awolowo University Teaching Hospital from January 1993 to December 2004 were reviewed. Information extracted and analysed included age of patient, sex, presentation, investigations, indication, type and outcome of nephrectomy, histopathology result and duration of follow up. RESULTS: During the period, thirty adult patients mean age 42.73 yrs (range 16-80 yrs, M:F = 2:1) were scheduled for nephrectomy. Indications included suspicion of malignancy in 19 (63.3%) patients, protracted loin pain in non-functioning kidney in 2 (6.7%), uncontrollable bleeding in a patient with bilateral polycystic kidney (3.3%), pyonephrosis with septicaemia in a patient (3.3%), kidney injury (grade 5) in 2(6.7%) and kidney donation for transplantation in 3(10%). Ultrasound and intravenous urography were useful in the patients' evaluation. Twenty-seven (90%) patients were operated upon, but only 25 (83.3%) had nephrectomy. Sixteen (53.3%) had radical nephrectomy, 5 (16.7%) had simple nephrectomy, 3 (10%) had nephro-ureterectomy, and one (3.3%) had partial nephrectomy. Major surgical complications included wound sepsis (18.5%) and primary haemorrhage (7.4%). The overall morbidity and mortality rates were 7.4% and 3.7% respectively. Postuninephrectomy, patients' renal function remained stable after an average of 34.05 months follow-up. CONCLUSION: Renal tumours constitute the main indication for adult nephrectomy in our community. Kidney injury, kidney donation, and pyonephrosis are relatively uncommon indications. Open nephrectomy, which remains our local practice, is safe and unilateral nephrectomy is compatible with normal life.

SCROTAL SQUAMOUS CELL CARCINOMA AND ASSOCIATED BLINDNESS: A CASE REPORT AND LITERATURE REVIEW.

BACKGROUND: Carcinoma of the scrotum is a rare disease which has been linked with occupational exposure to certain industrial carcinogens. Scanty reports of scrotal carcinoma exist in literature but in very few places worldwide. To our knowledge, there has been one documented report of scrotal carcinoma in our country and this is the first report of scrotal carcinoma in over 45years existence of our tertiary Health institution. We present the clinical evaluation, investigations and surgical intervention of a blind elderly welder with squamous cell carcinoma of the scrotum at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria. CASE PRESENTATION AND MANAGEMENT: A 65 year-old blind welder presented to us with a painless fungating scrotal mass of two years' duration. He had prior incision and drainage of the swelling in a primary health centre but this failed to heal, with copious purulent discharge. The mass measured 20cm x 15cm x 8cm and was inseparable from the right testis and cord structures, with infiltration of the root of the penis. The inguinal lymph nodes were not enlarged. CT scan confirmed localized scrotal tumour and biopsy confirmed squamous cell carcinoma.He subsequently had wide local excision of the scrotal tumour (with at least 2cm free margins), right total orchidectomy and advancement flap closure of scrotal defect. Histopathological reports corroborated the earlier findings and confirmed tumour free margins. He has remained well 18 months after surgery. CONCLUSION: Squamous cell carcinoma of the scrotum, though rare, is the commonest malignancy affecting the scrotum worldwide. Surgery still remains the mainstay of treatment and early intervention improves the chances of a favourable outcome.

Giant renal oncocytoma masquerading as infiltrating renal cell carcinoma: case report and literature review.

Renal oncocytomas (RO) are tumours containing a population of cells with highly differentiated eosinophilic granular cytoplasm, extremely rich in mitochondria. It is estimated they account for about 3 to 7% of all solid renocortical tumours that were previously regarded as renal cell carcinoma. Based on their clinical behaviour and distinct pathologic features they are now regarded as benign renal tumours, often less than 5cm in diameter. We present a case of giant renal oncocytoma in a patient with synchronous bladder tumour, with pre-operative clinical, urographic and ultrasound features of locally advanced renal cell carcinoma (RCC). Findings at surgery included huge right renal tumour with infiltration to the duodenum; hepatic colic flexure; gall bladder; liver capsule and the greater omentum with small indurations at the base of the bladder. There was no tumour extension to the renal vein, no peritoneal seedling, no nodal metastasis and no ascites. Radical nephrectomy was carried out with good prognosis and without recurrence 52months post nephrectomy. This presentation, besides highlighting the possible giant nature of RO, also illustrates the malignant potential of RO to infiltrate contiguous structures and mimics infiltrating RCC. In view of the difficulties at establishing pre-operative diagnosis in this disease and because nephron-sparing surgery is curative, especially for the well-circumscribed tumours, RO should be considered in the management of patients with features of infiltrating RCC. A review of literature is also presented.

Internal jugular and subclavian catheterisation: indications, problems and prospects in a Nigerian dialysis centre.

AIMS AND OBJECTIVES: To highlight the indications, problems and prospects of bedside non-surgically inserted jugular and subclavian dual lumen catheters. PATIENTS AND METHODS: Renal failure patients being managed in our centre with indications for central catheterisation were consecutively recruited at presentation. They had bedside non-surgical jugular and subclavian insertion of central catheters using modified Seldinger wire technique and the performance of the catheters monitored. RESULTS: Sixteen patients aged between 23 and 65 years had 32 central catheterizations during the 12-month period. The indications included its use as haemodialysis access in all catheterisations, additional indications were CVP monitoring in 5, and parenteral hyperalimentation in 1. Three catheterisations were in right subclavian vein, 4 in left internal jugular vein and 25 in right internal jugular vein. The duration of use ranged between 3 days and 11 weeks and blood flow rate used ranged between 250 and 350 mls/min. Nine (28.1%) catheterisations were complicated with exit site and systemic infection. Catheter blockage and accidental catheter removal were recorded in 3 patients each. Carotid artery puncture was recorded in 2 patients but haemostasis was maintained with direct digital compression. CONCLUSION: We conclude that percutaneous bedside internal jugular and subclavian (venous) catheterisation using dual lumen catheter is safe and devoid of major complications.

Kidney transplantation in a developing economy: challenges and initial report of three cases at Ile Ife.

BACKGROUND: Kidney transplantation (KT) is globally adjudged the best alternative treatment for end stage renal disease (ESRD) in preference to life-long dialysis. This form of therapy was hitherto unavailable in Nigeria until our hospital and a private hospital embarked on a KT programme despite our depressed economy, and inadequate facilities. We present the initial report of KT performed in our hospital and the challenges of KT in our developing society. CASE REPORTS: Three patients with ESRD had living related KT between June 2002 and April 2003. The first patient died with functioning graft six and a half months post transplantation from complications of Diabetes mellitus and sepsis, while the remaining two still enjoy a good quality of life 35 months post transplantation. There were problems with procurement and monitoring of immunosuppressive drugs in the three patients. This report also illustrates the common causes of ESRD in Nigeria and some of the complications of KT. To our knowledge, these are the first reported cases of KT in Nigeria. CONCLUSION: Kidney transplantation is cost effective and offers a good quality of life for ESRD patients. Poverty, inadequate facilities and lack of donors are major problems facing KT in our society. Although KT requires high technical and material resources, with proper training, commitment and adequate funding, it is feasible, safe and cheaper on a long term basis for the management of patients with ESRD in a developing economy like ours. There is a need for government funding of KT programmes in developing countries.

Accidental injuries and cutaneous contaminations during general surgical operations in a Nigerian teaching hospital.

OBJECTIVE: To determine the prevalence of accidental injuries and body contaminations among the operating personnel during general surgical operation, those involved, the circumstances surrounding the injuries or body contaminations and the factors affecting the prevalence in a unit of a teaching hospital in Nigeria. DESIGN: Patients operated for general surgical conditions in a unit of a Teaching Hospital Complex during a period of two years (1997-1998) were studied. A proforma was designed to enter personal biodata, preoperative and intra-postoperative clinical information of all the patients. SETTING: Wesley Guild Hospital a unit of teaching hospital complex serving the large agrarian rural and semi-urban Nigerians. PATIENTS: Five hundred and eighty nine consecutive general surgical patients. All types of general surgical operations were included, emergency or elective, major or minor, carried out during the day or at night. INTERVENTION: All the patients were operated and operating personnel observed for sharp injuries and body contamination. MAIN OUTCOME MEASURES: Incidence of sharp injuries and cutaneous contamination and personnel at risk determined. RESULTS: Operating personnel sustained 62 sharp injuries (10.5%), these were caused by suture needle in 57 cases (92.0%), towel clips in three (4.8%), knife cut in two (3.2%). Operating physicians sustained 56 cases of sharp injuries (90.3%) and Scrub Nurses in six (9.7 %). Self-inflicted sharp injuries in 49 (79 %) and in 12 cases (21%) injuries were inflicted by the surgeons or their assistants. Left hand was injured in 39 cases (63%) and right in 23 (37%). Cutaneous or mucosa membrane contamination with blood or body fluid occurred in 232 cases (39.4 %). These were made up of wet gown contamination in 124(53.5 %), glove failure in 72(31%) and splashing of blood or fluids into the face or eyes in 36 cases (15.5 %). Contamination occurred in more than one operating personnel in more than half of the cases. Operating surgeons were affected in 211 cases (91%). The risks of accidental injuries and blood and body fluid contamination were significant, if the duration of the operation was more than one hour, among the operating surgeons and if the operation was major (p<0.05). CONCLUSION: This study has demonstrated that cutaneous, percutaneous, and mucous membrane exposure to patients blood and body fluids are common events during general surgical operations. Most accidental injuries were due to solid suture needle-sticks, mostly injured personnel were the primary operating surgeons, injuries occurred predominantly on the left hand. This may poses a significant risk of infection with blood borne pathogens when operating on infected patients.

Obstructed abdominal hernia at the Wesley Guild Hospital, Nigeria.

OBJECTIVE: To determine the incidence, pattern and outcome of obstructed abdominal wall hernia in a semi-urban and rural community. DESIGN: A proforma was drafted to study all consecutive patients operated for obstructed anterior abdominal wall hernia over a period of five years. Clinical findings, preoperative treatment, operative findings and postoperative outcome were documented. SETTING: Teaching hospital located in a semi-urban community comprising mostly agrarian population. PATIENTS: A total 110 adult patients with obstructed anterior abdominal wall hernia who had operative intervention and other postoperative management. RESULTS: There were 110 patients with 111 obstructed hernias, accounting for 26.4% of all abdominal wall hernias. The age ranged from 19-79 years with mean of 49.7 years. Males accounted for 81%. Inguinoscrotal hernia was the commonest occurring in 75.7%, 16.2% patients presented with inguinal hernia and five patients with femoral hernia. The greater proportion of inguinal hernia occurred in female. Eighty seven patients (79%) had emergency operations and elective in 23 patients (21%) who had spontaneous reduction while awaiting surgery. Ninety two percent of inguinoscrotal/inguinal hernia were indirect. Omentum was trapped in 52 hernias (47.%), while in 15 patients (13.6%), gangrenous bowel segments were discovered. Scrotal oedema was the commonest complication accounting for 21%, while wound infection occurred in 20%. There were three deaths in elderly men with clinical symptoms and signs of acute intestinal obstruction and gangrenous bowel segments, accounting for 2.7% of the patients. Twenty eight per cent of patients were discharged within the first and second postoperative days. Two patients spent 36 and 56 days each in the hospital. CONCLUSION: This study showed that 26.4% of abdominal hernia presented with obstruction. With inguinoscrotal hernia predominating: male accounted for 81% and 13.6% of the obstructed hernia contained gangrenous bowel segments. Post-operative complications were common, mortality occurring mainly in elderly patients with late presentation.

Priapism in southwestern Nigeria.

OBJECTIVES: To determine the aetiology, pattern of presentation, treatment regimen and outcome of management of priapism in our environment and to compare our findings with previous studies in this country and elsewhere. DESIGN: A 10-year retrospective study from January 1991 to December 2000. SETTING: Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. PATIENTS AND METHODS: Hospital records of 16 patients managed for priapism over 10 years (January 1991 to December 2000) were analysed. Information extracted included the age, occupation, duration of symptoms, precipitating factors, past medical history, haemoglobin genotype, drug and social history, physical findings, treatment regimen, outcome of treatment, complications and duration of follow up. Eighteen patients were treated for priapism during the period but only sixteen case files available for analysis were reviewed in this study. RESULTS: The mean age of the 16 patients under review was 20.4 years (range: 2.5-38 years). Thirteen patients (81%) were single and 10 (62.5%) were students. All the patients presented late with pain and woody hard penis with mean duration of eight days (range; 7 hrs-30 days). Eleven patients (68.7%) had previous episodes of priapism. Fourteen patients (87.5%) had sickle cell disease (SCD) and two (12.5%) were psychiatric patients on oral chlorpromazine. Associated medical conditions include urinary tract infection, malaria, acute urinary retention, bone pain crises and acute psychosis. All the patients received initial conservative management. Six patients had needle aspiration with irrigation plus injection of 2 ml of adrenaline solution (1 ml 1/1000 adrenaline in 200 ml saline) in both corpora cavernosa. One (16.7%) out of the six patients achieved full detumescence with normal erection. The remaining five patients later had cavernotomy with full detumescence and normal erection in three (60%) and weak erection in two (40%). Eight patients had Cavernosa-glandular shunt, full detumescence and normal erection was achieved in five patients (62.5%) while three (37.5%) became impotent. Two of the three patients with impotence presented with the longest duration of symptoms (14 and 30 days respectively), while the third patient reported earlier after five days, but he had suffered more than six (>6) previous attacks of priapism. Duration of hospital stay was 3-10 days and the average duration of follow up was 80.7 weeks. CONCLUSION: Sickle cell disease account for 87.5% of priapism in our community. Late presentation and previous episodes of priapism, which are common features in most of these patients, are associated with poor prognosis with higher risk of impotence. Conservative management and aspiration with intracavernous adrenaline therapy appears ineffective in late case. However, good results obtained with surgery indicate that late presentation should not be a deterrent to surgical intervention. Surgeries in form of cavernotomy or cavernosa-glandular shunt, when carefully done, are effective and safe.

Penile fracture in a patient with stuttering priapism.

Penile fracture commonly results from trauma of sexual intercourse or masturbation. It is common in the Middle East and America, but rare in Nigeria and sub-Sahara Africa. We present a case of penile fracture, an uncommon urologic emergency, complicating priapism, another urologic emergency; precipitated in an unusual circumstance. This report illustrates a 30-year-old undergraduate who has suffered stuttering priapism for about a week and developed penile fracture while forcefully packing the erect organ. He presented early in the hospital and had emergency surgical repair. Prognosis was good. A review of literature is also presented. Immediate surgical repair offers good prognosis in the management of this emergency.
