RESUMEN
INTRODUCTION: Prostate cancer is still the leading male cancer and the leading cause of cancer deaths in Nigeria, and other low- and middle-income countries (LMIC) in Sub-Saharan Africa. Early diagnosis is essential to ensuring prompt treatment and reducing morbidity and mortality. Reducing the waiting times for diagnosis and treatment is therefore important. AIMS AND OBJECTIVES: To study prostate cancer management waiting times, to serve as a baseline in improving the quality of cancer care in the Nigerian populace. PATIENTS AND METHODS: This was a ten-year retrospective study of waiting times of all histologically-confirmed prostate cancer patients seen at Alex-Ekwueme Federal Teaching Hospital, Abakaliki, Ebonyi State, Nigeria. Statistical analysis was done SPSS version 26. A P-value less than 0.05 was considered statistically significant. RESULTS: A total of 189 patients presented with prostate cancer; however, 73 patients with complete data were analysed. The mean age of the patients was 71.48±8.16 years. The median duration of symptoms before presentation was 6 months. The mean total prostate-specific antigen was 82.08±54.9ng/mL. The mean duration between the first visit to the definitive diagnosis was 6.53±11.68 months with a median of 1 month. The median duration from visit to treatment was 3 months with a mean of 9.71±13.4 months. There were no associations between occupation, highest educational level, financial constraints, and the different waiting times studied (P>0.05). CONCLUSION: The waiting times for prostate cancer management were unduly prolonged in this study; patient-related factors did not influence this wait. INTRODUCTION: Le cancer de la prostate est toujours le principal cancer chez les hommes et la principale cause de décès par cancer au Nigéria et dans d'autres pays à revenu faible et intermédiaire (PFR) en Afrique subsaharienne. Un diagnostic précoce est essentiel pour garantir un traitement rapide et réduire la morbidité et la mortalité. Il est donc important de réduire les délais d'attente pour le diagnostic et le traitement. OBJECTIFS: Étudier les délais d'attente dans la prise en charge du cancer de la prostate, afin de servir de référence pour améliorer la qualité des soins contre le cancer dans la population nigériane. PATIENTS ET MÉTHODES: Il s'agit d'une étude rétrospective de dix ans sur les délais d'attente de tous les patients atteints de cancer de la prostate confirmé histologiquement et traités à l'hôpital universitaire fédéral Alex-Ekwueme, à Abakaliki, dans l'État d'Ebonyi, au Nigéria. L'analyse statistique a été réalisée avec la version 26 du logiciel SPSS. Une valeur de P inférieure à 0,05 a été considérée comme statistiquement significative. RÉSULTATS: Un total de 189 patients ont présenté un cancer de la prostate ; cependant, seuls les 73 patients avec des données complètes ont été analysés. L'âge moyen des patients était de 71,48±8,16 ans. La durée médiane des symptômes avant la présentation était de 6 mois. La concentration moyenne d'antigène spécifique de la prostate (PSA) total était de 82,08±54,9 ng/mL. La durée moyenne entre la première visite et le diagnostic définitif était de 6,53±11,68 mois, avec une médiane de 1(1) mois. La durée médiane entre la visite et le traitement était de 3 mois, avec une moyenne de 9,71±13,4 mois. Aucune association n'a été observée entre l'occupation, le plus haut niveau d'éducation, les contraintes financières et les différents délais d'attente étudiés (P>0,05). CONCLUSION: Les délais d'attente pour la prise en charge du cancer de la prostate étaient anormalement prolongés dans cette étude ; les facteurs liés au patient n'ont pas influencé cette attente. MOTS-CLÉS: Cancer de la prostate, Délai d'attente, Délai, Diagnostic, Traitement.

Background: Pressure flow urodynamic study remains the gold standard for the diagnosis of bladder outlet obstruction; however, their use is limited by their relative unavailability in our environment, cost, and invasiveness. Measurement of bladder wall thickness (BWT) by transabdominal ultrasonography is a promising tool that can be used to diagnose bladder outlet obstruction in our environment where pressure-flow urodynamic study is not readily available. Objective: The study aimed to correlate BWT with uroflowmetry and to establish a BWT cut-off in patients with lower urinary tract symptoms (LUTS) due to benign prostatic enlargement. Materials and Methods: This was a prospective one-year study of patients with LUTS due to benign prostatic enlargement. The patients were divided into obstructed and non-obstructed groups with Q- max of 10 ml/s serving as the cut-off value. Receiver Operator Curve (ROC) was used to evaluate the performance of BWT in diagnosing BOO. Statistical significance was set at P < 0.05. Results: The mean BWT and Q-max were 4.53 ± 2.70 mm and 15.06 ± 9.43 ml/s. There was a negative correlation between BWT and Q-max (r = -0.452, P = 0.000), Q-average (r = -0.336, P = 0.000), and voided volume (r = -0.228, P = 0.046). A BWT cut-off of 5.85 mm was found to be the best threshold to differentiate obstructed from non-obstructed patients with a sensitivity and specificity of 70 and 88.2 percent respectively. Conclusion: Bladder wall thickness showed an inverse relationship with maximum flow rate with high sensitivity and specificity. This non-invasive test can be used as a screening tool for BOO in our setting, where the pressure flow urodynamic study is not readily available.

BACKGROUND: Nowadays, the practice of day case surgery (DCS) is an attractive and appealing one with widespread acceptability because of numerous benefits. AIM: This study aimed at presenting our experience with urologic DCS in a tertiary healthcare center. PATIENTS AND METHODS: A 5-year review of all day-case urologic surgeries at our tertiary healthcare center was carried out. Data on patients' biodata including age and sex, diagnoses, indications and procedures performed, types of anesthesia, complications, admission and re-admission history were obtained from theatre records and patients' case notes. Data were analyzed using PASW Statistics version 18.0 and results presented in table and charts. RESULTS: A total number of 1277 of the 1825 urologic surgeries which took place during the study period were performed as day cases giving a proportion of 67.8%. The age range was 11 days to 94 years. The most commonly performed DCS are prostate biopsy, cystoscopy and varicocelectomy in 368 (28.8%), 165 (12.9%) and 163 (12.8%) patients respectively. Local anesthesia with or without sedation was the most commonly used in 981 (76.8%) cases. Twenty-four (1.9%) patients required unplanned admission for complications, 18 (1.4%), delayed completion of surgery, 4 (0.3%) and delayed recovery from anesthesia, 2 (0.16%). Three (0.2%) of these patients were re-admitted for management of sepsis following prostate biopsy. CONCLUSION: This study like numerous others demonstrated the feasibility, effectiveness and safety of DCS. To meet up with the global trends in DCS in Nigeria, there is need for investment in infrastructure and adoption of minimally invasive techniques to allow incorporation of more complex cases in the range of procedures offered as DCS.

BACKGROUND: Urological emergencies constitute a significant part of emergency presentations in various referral centers. Data on the prevalence of these emergencies in West African sub-region are sparse. OBJECTIVE: The study is aimed at determining the pattern of urological emergencies in our center and is geared towards bridging the gap in knowledge of the epidemiology of urological emergencies in this sub-region as a means of achieving efficient use of scarce resources. SUBJECTS AND METHODS: It was a retrospective study of all urological emergency cases that presented over six years in a Federal University Teaching Hospital in Nigeria. Data were collected from emergency register and theatre logs. Data analysis was done using SPSS version 25. RESULTS: A total of 267 patients presented with urological emergencies during the period of study with 258 (96.6%) men and 9 (3.4%) women. The mean age of the patients was 50.6 ± 20.8 years. Urinary retention was the most common urological emergency accounting for 159 (59.6%) cases followed by Fournier's gangrene 23 (8.6%) and testicular torsion 23 (8.6%). Bladder and ureteral injuries accounted for 5 (55.6%) of the urological emergency presentations in women while both injuries accounted for only 4 (1.6%) in men (P = 0.000). Urethral catheterization was the most commonly performed procedure 139 (52.1%), followed by percutaneous suprapubic cystostomy (SPC) 31 (11.6%). CONCLUSION: Urological emergencies have varying presentations in both sexes. Urinary retention, and acute scrotum were the most common urological emergencies in our facility. This knowledge can be used in emergency preparedness planning which involves personnel training and resource allocation.

PURPOSE: The use of flaps in the two-stage repair of posterior hypospadias associated with severe chordee has been well established. Despite the almost certain guarantee of flap take, complications such as diverticuli are still relatively high. While different applications of the tubularized incised plate have been described, experience with the application of the technique to the two-stage flap repair is very limited. A previous local review of 15 cases performed at the present institution during the period 1998-2003, using the technique as described by Rekit, revealed fistulae and diverticulum rates of 20% and 27%, respectively. With the primary objective of improving surgical outcome, the midline incision was incorporated into the two-stage flap repair. MATERIALS AND METHODS: Between 2004 and 2015, 35 boys (aged 2-15 years) with severe hypospadias that required excision of the urethral plate were operated using the two-stage flap technique. The first stage involved mobilization of preputeal or dorsal penile skin (if circumcised) to the ventral surface, as described by Retik. After a minimum interval of 6 months, the second-stage operation was performed in a way similar to the technique of tubularized incised plate urethroplasty, as popularized by Snodgrass, and involved a preliminary midline incision on the neo-urethral plate followed by tubularization and multilayered closure. RESULTS: All but one flap took successfully. The outcome was satisfactory in 80% of patients, and there was a fistula rate of 14% ( Summary Table). One patient had a complete breakdown of the flap and was successfully treated about 12 months later by repeating the second stage of the operation. No case of diverticulum or stricture was recorded. DISCUSSION: Even though there was a marginal improvement in the fistula rate, the most striking observation was the complete absence of diverticulum or stricture. With a reported incidence rate of 20-63%, different authors have reported diverticulum formation (despite the absence of distal obstruction) to be a major problem of the two-stage flap technique. Attempts by these authors at reducing the risk of diverticulum by reducing flap size have tended to increase the risk of strictures. This has been the main reason given by some authors for abandoning the technique. The main limitations of the present study included the wide age range of the patients and the small sample size. CONCLUSION: The inclusion of a midline incision in a two-stage flap urethroplasty for proximal hypospadias appears to prevent the development of diverticulum.

BACKGROUND: Patient discomfort secondary to an indwelling urethral catheter in the post operative period can be very distressing. These symptoms resemble the overactive bladder (OAB) syndrome. Muscarinic receptor blockers have been successful in the management of OAB. However, information on the use of these drugs in the management of the postoperative catheter-related bladder discomfort (CRBD) in sub-Saharan Africa is still relatively sparse. OBJECTIVE: To assess the efficacy of preoperative oral tolterodine in the management of CRBD in surgical patients in the immediate postoperative period. METHODS: This was a double-blind placebo-controlled study consisting of 56 patients in each arm who underwent general anesthesia. Each patient was given oral tolterodine or placebo 1 hour before the induction of anesthesia. The patient was later assessed at the recovery room at intervals after recovery from anesthesia. The presence of CRBD was noted and graded. RESULTS: The overall incidence of CRBD in both the tolterodine group and the control were 85.7% and 91.1%, respectively. Overall, tolterodine prophylaxis (TP) was associated with an absolute risk reduction (ARR) of 5.4%, relative risk reduction (RRR) of 5.8%, and a number needed to treat (NNT) of 19. The incidence of moderate-to-severe CRBD in the tolterodine and control groups were 10.7% and 78%, respectively, with an ARR of 74.5% with TP. CONCLUSION: TP does not significantly reduce the incidence of CRBD in the immediate postoperative period but appears to be efficient in the reduction of the severity of postoperative CRBD.

BACKGROUND: Organ transplantation program in developing countries is still significantly dwarfed. Health workers are undeniably important in the success of transplantation. OBJECTIVE: To assess the knowledge and attitude of health workers toward organ donation in South-West Nigeria with a view to explaining reasons for these shortcomings. METHODS: In a cross-sectional study conducted on 850 health care workers, self-administered questionnaires were used to obtain information from participants. RESULTS: Of 850 participants, 766 (90.1%) returned their completed questionnaires. The mean±SD age of participants was 36.7±9.2 years. Majority (93.3%) of participants had heard of organ donation; 82.5% had desirable knowledge. Only 29.5% and 39.4% would be willing to donate and counsel potential organ donors, respectively; 36.5% would consider signing organ donation cards. Only 19.4% believed that organ transplantation is often effective and 63.4% believed they were permitted by their religion to donate. Permission by religion (OR 3.5; 95% CI 2.3 to 5.3), good knowledge (OR 2.9; 95% CI 1.4 to 5.7), readiness to sign donation cards (OR 2.6; 95% CI 1.7 to 3.8), discuss organ donation (OR 2.7; 95%CI 8.0 to 63.8), and knowing somebody who had donated (OR 2.9) independently influenced willingness to donate organ. CONCLUSION: There is disparity in knowledge of organ donation and willingness to donate among health care workers. Efforts should be intensified to give comprehensive and appropriate education to health care workers about organ donation to bridge this gap.
RESUMEN
Choristoma is development of a normal tissue in an aberrant location. This report describes jejunal salivary choristoma (JSC) causing recurring episodes of abdominal discomfort in a 5-year-old girl. Exploratory laporatomy revealed a pale yellow subserosal jejunal lesion. Wedge resection of the lesion and repair of the bowel were performed. The child did well postoperatively and has since that time been free of pain at follow-up. Histopathological examination of the resected lesion revealed salivary gland choriostoma. Literature review (PUBMED search engine) revealed no previous report of this rare clinicopathologic entity. We conclude that choriostoma should be considered a possible differential when evaluating abdominal complaint in children.
RESUMEN
The human immunodeficiency virus (HIV) infection has become a pandemic with more than 40 million infected people worldwide. The virus attacks the immune system of the host thus exposing them to opportunistic infections in various systems of the body. The use of highly active anti-retroviral therapy (HAART) has converted a previously lethal condition to a chronic condition with relatively benign cause. This has allowed infected patients to live longer than before. Though beneficial, however, this has been associated with increased incidence of complications seen in these patients involving many systems. Urogenital system is not an exception to this and indeed is a common site for these complications. Urological symptoms or signs are often seen in HIV patients and sometimes appear as the first indicator of the disease. These manifestations can be benign or malignant, infective or non-infective, disease or drug-related. Their appearance may also be a pointer to the deterioration of the infection into a full blown AIDS. It is therefore important that every doctor has a good knowledge of the possible urological manifestations of the disease. Early recognition and prompt treatment of these complications may be of prognostic significance as they may produce significant morbidity and mortality if left untreated. This article highlights the clinical features and management of common urological manifestations of HIV.

OBJECTIVE: To evaluate the usefulness of prostate specific antigen (PSA) and digital rectal examination (DRE) in the diagnosis of cancer of the prostate (CaP) amongst unscreened patients. PATIENTS, MATERIALS AND METHODS: A prospective study 168 unscreened men who were referred for evaluation for CaP. They all had a 10-core extended transrectal prostatic needle biopsy using size 16 Tru Cut needle for either an elevated serum total PSA of > 4 ng/ml or abnormal DRE findings or both. Overall cancer detection rate was determined and detection rates were determined separately for patients with elevated PSA with normal DRE, abnormal DRE with normal PSA and those with both indications. The performances of each indication were determined separately and in combination in terms of their sensitivity, specificity, predictive values and accuracy. The results were compared amongst patients with different indications for biopsy. RESULTS: The overall cancer detection rate was 44.0%. Detection rates in patients with elevated PSA with normal DRE and abnormal DRE with normal PSA were 30.0% and 17.4% respectively. There was statistically significant increased detection of 61.2% amongst patients with both indications. The overall sensitivities of PSA, DRE and combination of both were 94.6%, 75.7% and 70.3% respectively while the specificities were 20.2%, 44.7% and 64.9% respectively. The accuracies of PSA, DRE and combination of both indications were 53%, 58% and 67.3% respectively while the PPVs were 48.3%, 51.9% and 61.2% respectively. Mean Gleason score was 6.82 while the overall complication rate was 23.2% CONCLUSION: Neither PSA nor DRE is sensitive, specific, predictive or accurate enough on its own to be an ideal screening or diagnostic test for CaP. Therefore, optimal evaluation of patients with suspected CaP is best achieved with both even in unscreened populations.

BACKGROUND: Nigeria with a growth rate of 28%, accounts for over two thirds of the West African population. It also has one of the highest maternal mortality rates in the world with contraceptive prevalence among married couples less than 10%. Despite its safety and efficacy vasectomy appears to be unpopular in our environment. OBJECTIVE: To assess the perception and acceptance of married men and women towards vasectomy and the influence of the spouse on the man's decision to accept or reject vasectomy. DESIGN: A cross sectional questionnaire based study. SETTING: With an estimated population of 20 million, Lagos is the most cosmopolitan and urbanised city in Nigeria and accounts for 65% of all commercial activities in the country. Virtually all the tribes in Nigeria are represented in the city. SUBJECTS: Literate pregnant women recruited from the antenatal clinics and literate new fathers. All subjects were recruited from three health facilities in the Lagos metropolis. RESULTS: Twenty seven point five and twenty one percent of the men and women respectively had a good Knowledge of vasectomy while 49.1% and 19% of all men and women respectively with good knowledge would accept vasectomy (or agree for their spouses to have the procedure). Overall acceptance rates for men and women were 26 and 13.5% respectively while 92% of men who can opt for vasectomy will only do so if their spouses agree. Knowledge about vasectomy was the strongest single factor influencing the acceptance of vasectomy (p= 0.013) with stronger correlation among men than women (p=0.005 vrs p=.0.023). CONCLUSION: Knowledge and acceptance of vasectomy is significantly better in males than female Nigerians living in Lagos.

Intrauterine contraceptive device (IUCD) is a commonly utilized reversible contraceptive technique especially in the developing world. Though effective, it is not immune to complications. Migration of the device is a rare but serious complication which may be symptomatic or asymptomatic. We report a case of a 45yr old woman who had IUCD inserted 20 years earlier and had forgotten about it since she subsequently had three full term pregnancies leading to successful vaginal deliveries. The forgotten IUCD was discovered incidentally during evaluation of the woman for haematuria as it had migrated to the wall of the bladder. The case is reported to increase index of suspicion as detailed clinical history is important in evaluating cases of haematuria.

AIMS AND OBJECTIVES: To compare the cancer detection rates of sextant and ten- core biopsy protocol amongst patients being evaluated for prostate cancer. PATIENTS AND METHODS: This is a prospective study involving 125 men with suspicion of prostate cancer. They all had an extended 10-core transrectal digitally-guided prostatic biopsy using Tru-Cut needle. Indications for biopsy were presence of one or more of the following: elevated Prostate Specific Antigen (PSA), abnormal Digital Rectal Examination (DRE) findings and abnormal prostate scan. Sextant biopsies were collected first, followed by four lateral biopsies in all patients. Both groups of specimen were kept and analyzsed separately by the same pathologist. The cancer detection rates of sextant and extended (combination of sextant and lateral) 10-core biopsy protocols were determined and compared. Pearson's Chi square and McNemar tests at two degrees of freedom with level of significance set at 0.05 ( P <0.005) were used to determine the statistical significance. RESULTS: The overall cancer detection rate of 10-core prostate biopsy was 48.8%. Of all positive biopsies, the sextant biopsy protocol detected 52 cancers (85.2%) while the lateral biopsy protocol detected 58 cases (95.1%). Three (3) cancers were detected by the sextant protocol only while the lateral protocol detected nine (9) cancers where sextant technique was negative for malignancy. Ten-core extended protocol showed a statistically significant increase of 14.8% over the traditional sextant. (P=0.046). The overall complication rate of ten-core biopsy was 26.4% and the procedure was well tolerated in most patients. CONCLUSION: We conclude that a ten-core prostate biopsy protocol significantly improves cancer detection and should be considered as the optimum biopsy protocol.

OBJECTIVE: To determine the significance of an extended 10-core transrectal biopsy protocol in different categories of patients with suspected prostate cancer using digital guidance. MATERIALS AND METHODS: We studied 125 men who were being evaluated for prostate cancer. They all had an extended 10-core digitally guided transrectal prostatic biopsy done for either an elevated serum prostate-specific antigen (PSA) or an abnormal digital rectal examination finding or both. Sextant biopsy samples were collected first, followed by additional four lateral biopsies in all patients. Both groups of specimens were analyzed separately. The cancer detection rates of both sextant and extended 10-core biopsy protocols at different PSA levels and digital rectal examination (DRE) findings were determined and compared. The level of significance of difference in cancer detection was determined using Pearson's Chi square test with level of significance set at <0.05. RESULTS: The overall cancer detection by the extended technique was 61 (48.8%) cases while the sextant protocol detected cancer in 52 cases. The 10-core extended protocol yielded an increase in cancer detection rate of 14.8% but the improvement in detection rate was only statistically significant in the sub-set of patients with PSA between 4.1 and 10 ng/mL, with or without abnormality on DRE, with an overall increase detection rate of 33%.(P=0.04) CONCLUSION: Our study has shown that a 10-core prostate biopsy protocol significantly improves cancer detection in patients with suspected early cancer. It should therefore be the optimum biopsy protocol for patients with gray-zone PSA value, with or without abnormal DRE.

OBJECTIVES: To assess the value of percentage free prostate-specific antigen (%fPSA) in the detection of prostate cancer among Nigerian men with an intermediate total PSA level (4-10 ng/mL), and to show if the optimum threshold for biopsy is different from Caucasian values when the widely used (six-core, digitally directed) prostate biopsy protocol in Nigerians is applied. PATIENTS AND METHODS: The study included 105 patients aged >50 years, with a palpably benign prostate gland and intermediate levels of total PSA (4-10 ng/mL). These patients had a free PSA assay and a transrectal digitally directed six-core biopsy of the prostate. The %fPSA was calculated and the optimum threshold value for detecting prostate cancer was determined. RESULTS: The mean (SD) age of the patients was 64.4 (6.6) years and their mean (SD) total PSA level was 6.6 (1.7) ng/mL. Of these men 14 (13.3%) had cancer of the prostate detected by the prostate biopsy. The %fPSA level related directly to sensitivity values but inversely to the specificity and the positive predictive values. The best threshold of %fPSA for detecting cancer in these men was <40%, with a sensitivity of 100%, specificity of 93.4% and a positive predictive value of 70% (P < 0.05). CONCLUSIONS: In evaluating Nigerian patients with a palpably benign prostate gland and within the intermediate total PSA range, when digitally directed biopsy protocol is adopted, a %fPSA threshold of <40% will detect significant percentage of those with prostate cancer, with a minimal number of unnecessary biopsies. This value differs from that reported in western studies in which transrectal ultrasonography-directed biopsy was used.

OBJECTIVE: To present a 10year retrospective histologic study of prostate diseases in Lagos, Nigeria. The aim is to document the prevalence, histologic pattern, age distribution and PSA values of prostatic diseases. MATERIALS AND METHODS: The materials consisted of slides, paraffin embedded tissue blocks, patients case files and histology request forms of all prostatic biopsies received at the Morbid Anatomy department of Lagos University Teaching Hospital Idi-Araba, Lagos from 1999 to 2008. Each sample represents a different patient. RESULTS: Prostatic biopsies comprised 3.6 % of all biopsies in LUTH. BPH was the commonest prostatic lesion and accounted for 70.9% of all cases. The age range was 40 to 94 years with a mean of 67 years and a peak age group at 60-69 years. Stromoglandular pattern was the most common histological type of BPH accounting for 72.2 %( 393) of the cases. Malignant tumours constituted 28.9% of all prostatic biopsies. Most (93.7%) of these malignancies were seen in trucut biopsies. Adenocarcinoma accounted for 99.1% of the total 222 malignant tumours. It showed an age range of 40 to 98 years, a mean age of 66 years and peak prevalence in the 60-69 year age group. Gleason score nine was the most frequent (16.8%) in occurrence. Most adenocarcinomas were poorly differentiated (40%). Incidental carcinoma was seen in 4.2% of prostatectomy samples. High grade PIN was seen in 19.1% of adenocarcinoma cases. The most common inflammatory lesion was chronic non-specific prostatitis accounting for 76.4% of all inflammatory lesions. Malignant and benign lesions were accountable for PSA levels of 1 to 49.9ng/ml while values of 50ng/ml and above were seen exclusively in malignant lesions. CONCLUSION: Prostatic lesions constitute a significant source of morbidity among adult males in Lagos. Adenocarcinoma is the commonest histologic subtype of prostatic cancer and most are of poorly differentiated variety. Elevated levels of tPSA in Nigerian males may be as a result prostate cancer, BPH or BPH with prostatitis. PSA should in our opinion be used as a component of a strategy integrating multiple diagnostic approaches for prostate cancer screening and not to be used alone in our environment.

BACKGROUND: Urethral catheterization is a common minimally invasive procedure with well-known complications some of which may be severe. Quite often, a clinician is invited to manage the short and long-term complications of the procedure without adequate records of the procedure itself. OBJECTIVES: This study aims to determine the quality of documentation of urethral catheterization in our health institution. METHODS: This prospective study was carried out over a period of 1 month. The documentations in the medical notes and nursing records with respect to urethral catheterisation were assessed using 10 different parameters with the aid of a pro-forma. Statistical analysis was done with the Wilcoxon signed ranks test. RESULTS: A total of 89 patients were catheterised in the wards, the emergency departments and the theatre. All the catheterizations were performed by doctors. The overall quality of documentation of catheterisation was poor: It was significantly worse in the medical notes than the nursing records with 28% of all cases documented by the nurses not documented by the physicians. Documentation in the theatre and emergency were worse, while there was no documentation of aseptic technique in any patient. An 11% incidence of complications was noted. CONCLUSION: The quality of record keeping concerning urethral catheterization was inadequate. This is important not only for patients' care, but also for medico-legal purposes. We therefore recommend regular audit and introduction of protocols for proper documentation.
