A Bone Scan Is Valuable for Primary Staging of Newly Diagnosed Prostate Cancer in a Low-Resource Setting (Nigeria).

Objective: There is a paucity of information on bone scanning for prostate cancer from low-resource countries. This study evaluated the role of bone scan in the primary staging of newly diagnosed prostate cancer in one such setting. Methods: A retrospective analysis of 126 men with newly diagnosed prostate cancer undergoing an initial staging bone scan between January 2017 and December 2020 was carried out at a regional nuclear medicine center in Nigeria. Bone scan results were analyzed according to age, serum level of baseline prostate-specific antigen (PSA), and Gleason score. Equivocal scans and patients with no Gleason score or baseline PSA were excluded from the analysis. p < 0.05 was said to be significant statistically. Results: Of 111 patients (aged 38-84 years, median 66 years), who met the inclusion criteria, 26 (23%) men had evidence of bony metastases as shown by a positive bone scan. Higher PSA levels and Gleason scores were associated with an increased risk of a positive bone scan, p < 0.001. No patient with a PSA level < 20 ng/mL and a Gleason score of < 7 had a positive bone scan. Conclusion: The role of bone scanning in staging newly diagnosed prostate cancer patients in Nigeria is consistent with global reports. Our study confirms that a bone scan finding is well associated with the risk classification using PSA and Gleason score in our population.

Extra-adrenal phaeochromocytoma in a resource poor setting: A case report.

Phaeochromocytomas are catecholamine-secreting tumors arising in the chromaffin cells of the adrenal medulla. They are a rare cause of secondary hypertension. However, catecholamine secreting tumors may also be found in the extra-adrenal sites, producing similar symptoms as the adrenal phaeochromocytoma. The extra-adrenal phaeochromocytomas, are referred to as paragangliomas (PGLs). About 75% of extra-adrenal phaeochromocytomas are intra-abdominal, mostly located in perinephric, periaortic, and bladder regions. Most phaeochromocytomas secrete excessive amount of epinephrine and norepinephrine, whereas most paragangliomas secrete only norepinephrine. The excessive secretion of these products could lead to paroxysms of symptoms that could be life threatening. Medical management is initially offered, but definitive treatment involves surgical removal of the tumor, which requires promptness on the both the clinician and the patient sides. We present a case of an extra-adrenal phaeochromocytoma in an adult male with revealing imaging of a mass surrounding the bladder. The patient was managed with both alpha- and beta-adrenergic blockers. He declined the surgery and eventually died after appearing in an acute hypertensive crisis.

Cosmetic Appeal, HRQoL, and Effectiveness of Simple and Pseudotesticular Techniques of Orchidectomy in Prostate Cancer.

INTRODUCTION: Orchidectomy is the most cost-effective means of hormonal therapy for locally advanced or metastatic prostate cancer (LAMP). However, cost-effectiveness should not detract from health-related quality of life (HRQoL) considerations. Bilateral simple orchidectomy (BSO) has been linked to negative psychometric deficits from an empty scrotum. This study compared the HRQoL, therapeutic efficacy, and cosmetic appeal of BSO with endogenous pseudotesticular techniques of bilateral subcapsular orchidectomy (BSCO) and bilateral-epididymal-sparing orchidectomy (BESO). Research Design. Nigerian patients with LAMP were randomised into three surgical arms: BSO, BSCO, and BESO. Expanded Prostate Cancer Index Composite-26 HRQoL and sociodemographic questionnaires were administered before and three months after orchidectomy. Serum testosterone and PSA were measured at 0, 1, 2, and 3 hours; 7 days; and 3 months postoperatively. Pseudotesticular volumes and cosmetic appeal were assessed at 3 months. RESULT: Sixty-three patients were recruited (24 BSO, 21 BSCO, 18 BESO), 73% of whom were low-income earners. There was no significant difference in the procedure cost nor the PSA or testosterone nadirs achieved over the three-month follow-up period (11.3, 12.6, 15.2 ng/ml (p=0.667) and 0.44, 0.64, 0.79 nmol/l (p=0.603) respectively). Those with pseudotesticles (BSCO, BESO) felt less emasculated (p=0.010). BSCO produced the least sexual bother, highest sexual function, and largest pseudotesticular volumes. The cosmetic appeal scores were similar between groups (77.9 ± 22.8, 81 ± 13.9, and 81.9 ± 22.5, respectively, p=0.858). CONCLUSION: Endogenous pseudotesticular techniques, when compared with BSO, reduce the negative psychological impact experienced by patients without increasing costs. BSCO produced the best pseudotesticular volumes and postoperative sexual function. This study is registered with the ClinicalTrials.gov of the National Institute of Health U.S. National Library of Medicine as TEPSO study, NCT03744494: Comparison of the Therapeutic Efficacy and Patient Satisfaction of Three Techniques of Bilateral Orchidectomy in Prostate Cancer Patients of a Nigerian Sub-population.

Penile length of men attending urology outpatient clinic in Southwest Nigeria.

Penile length varies worldwide. It is necessary to determine penile length in our region to enable adequate counselling on normal length and reduce avoidable anxiety. Two hundred and seventy-one men were recruited with 97 men in group I and 174 men in group II. Mean ages were 38.4 ± 6.9 (21-50) years and 68 ± 9.1 (51-98) years. In group I, the mean flaccid penile length (FPL)-I and stretched penile length (SPL)-I were 9.8± 2.7 and 10.6± 2.2, mean height 1.7±0.07m and body mass index (BMI) 24.1±3.1 kg/m2. While in group II, mean FPL-II and SPL-II were 13.0± 2.9 and 14.1 ± 2.1, mean height was 1.69± 0.07m and BMI 24.3± 3.2 kg/m2. There were positive correlations between the SPL-I and heights in group I; (r=0.305, p<0.002); height and FPL-I (r = 0.218, P<0.032). Similarly, in group II positive correlations of FPL-II and SPL-II with height; r = 0.166 P<0.028 and r = 0.183, P<0.015. There was negative correlation SPL-II and BMI-II r-0.224, p<0.003. FLR-II and BMI-II, -0.157, p<0.039. In conclusion, Flaccid and stretched penile length of men < 50 years was smaller than those > 50 years. In both age groups, flaccid and stretched penile lengths correlated with height. In group II, penile lengths correlated negatively with BMI.

Incidental Prostatic Adenocarcinoma in Open Prostatectomy Specimens: An Institutional Experience.

Background: Prostatic diseases cause significant morbidity and mortality in African men. Most Nigerian patients presenting with huge prostate enlargement are availed open prostatectomy to relieve symptoms of prostatism. Some prostates removed for benign enlargement have indolent cancers that are only discovered after histopathological examination. The incidence of these incidental adenocarcinomas of the prostate varies widely. Methodology: We carried out a 10-year retrospective review of open prostatectomy specimens received in the Department of Pathology, from January 2009 to December 2018. At grossing, a minimum of 6 cassettes were used depending on size, and tissue was taken from representative areas for microscopic examination. The data was analysed for the presence of, and the relationship between, incidental adenocarcinoma of the prostate and clinicopathological parameters in each case using relevant statistical tools in the SPSS version 23. Results: Incidental adenocarcinoma of the prostate was found in 5.7% of 158 open prostatectomy specimens seen during the study period. High-grade prostatic intraepithelial neoplasm (HGPIN) was present in 1.9% of cases. Patients in the 7th and 8th decade accounted for 88.8% of all incidental adenocarcinomas. The mean weight of the excised glands was 89.8g (range10-500g). The weight of the prostate did not predict diagnosis of incidental adenocarcinoma. In-hospital consultation accounted for 66.9% of open prostatectomy samples received in the department but the majority (72.7%) of incidental adenocarcinomas were seen in specimens form external consultations. The tumours were mostly ISUP grade group one tumours. Conclusion: The rate of diagnosis of occult prostate cancer is low with majority of the tumours being well differentiated. Organ weight had no relationship with histological diagnosis. Cases managed outside the teaching hospital were more likely to have incidental prostate cancer.

Urethral steinstrasse: Day case care.

Urethral steinstrasse is rare. Only a few cases of spontaneous or postinterventional urethral steinstrasse have been reported in pediatric and adult patients. We report a case of a 52-year-old Nigerian man with a secondary urethral steinstrasse, and the treatment options possible, as day case procedures, under caudal anesthesia.

Erectile Dysfunction Among Men Attending Surgical Outpatients Department in a Tertiary Hospital in South-Western Nigeria.

BACKGROUND: Erectile dysfunction is becoming a public health issue with high incidences reported in community studies. OBJECTIVE: To evaluate the characteristics and outcome of treatment in men with erectile dysfunction in a tertiary center in Ibadan southwestern Nigeria. METHODS: Data of men with erectile dysfunction was retrieved between July 2004 and June 2014 and analyzed using SPSS version 16 statistical software. RESULTS: Eighty-nine men with erectile dysfunction were managed which constituted 2% of all urological cases seen during the study period. Their median and mean ages were 39 years and 39.6 ± 1.2SD (range 19-76 years). The peak age incidence at 30-44 years was 41.6% and reduced with increasing age after 65 years to 4.5%. The etiologies were psychogenic in 55%, organic in 27%, idiopathic in 17% and 1% was familial. 67.5%, 31.5% and 3.4% were married, single and separated respectively. Seventy percent neither smoked cigarette nor drank alcohol, 21.3% drank alcohol and 9% took both alcohol and smoked cigarette. Seventy seven and half percent of men presented within 5 years of their symptom. The treatments offered were PDE type 5 inhibitors alone or in combination with psychotherapy or modification of medications. The outcome of these treatments ranged from 89% to 91% success rate. CONCLUSION: The number of men with erectile dysfunction managed in the tertiary hospital is very low though the outcome of treatment is within acceptable range. Increase public enlightenment may encourage increase hospital patronage and access to the available treatments for erectile dysfunction.

Urethral obstruction from dislodged bladder diverticulum stones: a case report.

BACKGROUND: Secondary urethral stone although rare, commonly arises from the kidneys, bladder or are seen in patients with urethral stricture. These stones are either found in the posterior or anterior urethra and do result in acute urinary retention. We report urethral obstruction from dislodged bladder diverticulum stones. This to our knowledge is the first report from Nigeria and in English literature. CASE PRESENTATION: A 69 year old, male, Nigerian with clinical and radiological features of acute urinary retention, benign prostate enlargement and bladder diverticulum. He had a transurethral resection of the prostate (TURP) and was lost to follow up. He re-presented with retained urethral catheter of 4 months duration. The catheter was removed but attempt at re-passing the catheter failed and a suprapubic cystostomy was performed. Clinical examination and plain radiograph of the penis confirmed anterior and posterior urethral stones. He had meatotomy and antegrade manual stone extraction with no urethra injury. CONCLUSIONS: Urethral obstruction can result from inadequate treatment of patient with benign prostate enlargement and bladder diverticulum stones. Surgeons in resource limited environment should be conversant with transurethral resection of the prostate and cystolithotripsy or open prostatectomy and diverticulectomy.

Open haemorrhoidectomy under local anaesthesia for symptomatic haemorrhoids: An experience from Nigeria.

BACKGROUND AND STUDY AIMS: Ligation-excision haemorrhoidectomy is considered to be the gold-standard treatment for prolapsed haemorrhoids. The procedure is commonly done under general or regional anaesthesia. This study aimed to assess the feasibility and tolerability of open haemorrhoidectomy under local anaesthesia. PATIENTS AND METHODS: This is a prospective study carried out in Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria, over a 5-year period. All consenting adult patients with prolapsing haemorrhoids were offered Milligan-Morgan haemorrhoidectomy under local anaesthesia. They were assessed for tolerance and complications. RESULTS: More than 95% of the patients tolerated the procedure with manageable complications. CONCLUSION: Open excisional haemorrhoidectomy under local anaesthesia is feasible, safe and well tolerated in our environment, and may encourage early presentation of patients with piles to hospital.

Daycase urology at Ibadan, Nigeria: a ten year review.

INTRODUCTION: The objective of the study was to report the extent of urological surgeries performed as day cases in a major tertiary hospital in Ibadan and document the outcome. METHODS: We retrospectively reviewed the data of all urologic patients treated at the day-case theatre between January 2000 and December 2009. The parameters evaluated were: age, diagnosis, type of surgery/procedure, anaesthesia administered and the rank of the surgeon. Day case endoscopic procedures as well as prostate biopsies were excluded from the study. RESULTS: In total, 1292 patients were managed, 290 (22.4%) were children aged between 5 days and 15 years while 1002 (77.6%) adults aged between 17 years and 91 years. The majority of the procedures were carried out by the senior registrars (1169 cases, 90.5%) and consultants were involved in 123 cases (9.5%). General anaesthesia was primarily used in children (158 children vs. 4 adults), while local anaesthesia was used only in adults. 131 (45.2%) children had no anaesthesia for circumcision. The most common procedures performed in adults were varicocelectomy (426 cases, 42.5%), orchidectomy (332 cases, 33.1%), testicular biopsy (120 cases, 12.0%). While in children male circumcision (231 cases, 79.7%) was the main procedure performed. CONCLUSION: The day-case theatre is still suitable for day case urologic procedure in our setting. The common procedures are varicocelectomy, orchidectomy, and open testicular biopsy in the adults. While in children, male circumcision is commonly carried out.
