Acute urinary tract infection in patients with underlying benign prostatic hyperplasia and prostate cancer

Introduction: the occurrence of urinary tract infection in patients with obstructing prostate causes reduction in their health-related quality of life and overall well-being. The objective of this study was to determine the prevalence, risk factors and antimicrobial sensitivity pattern of pathogens causing urinary tract infection in patients with benign prostatic hyperplasia and prostate cancer. Methods: all patients who presented to our urology division with bladder outlet obstruction secondary to benign prostatic hyperplasia or prostate cancer between January 2016 and January 2019 were included. Information on age, co-morbid conditions, presence of an indwelling catheter, bacteriologic analysis, imaging findings and histological diagnosis were obtained and analyzed using SPSS version 20. Results: de-novo urinary tract infection occurred in 35.6% of patients while recurrent infection occurred in 5.9% of them. The most commonly isolated organisms were gram-negative bacteria with Escherichia coli, Klebsiella spp, Citrobacter spp and Aerobacter spp accounting for 62.2%, 27.0%, 8.1% and 2.7% respectively. Nitrofurantoin (64.3%), Ceftriaxone (46.3%) and Genticin (42.9%) were the three most sensitive antimicrobials to the organisms isolated. Only the presence of an indwelling catheter in the bladder was an independent predictor of urinary tract infection in the study population. Conclusion: about one-third of patients with benign prostatic hyperplasia and prostate cancer develop urinary tract infection. The predominant bacterial cause was Escherichia coli, which had a high degree of sensitivity to Nitrofurantoin. The presence of an indwelling catheter was the only independent predictor of this infection. Appropriate measures should be re-enforced to prevent the occurrence of catheter-associated infections

Prognostic Factors and Outcome of Management of Ischemic Priapism in Zaria, Nigeria

Objectives: The objective of this study was to determine the nuances of  management, prognostic factors, and outcome of ischemic priapism in patients seen at Ahmadu Bello University Teaching Hospital, Zaria, Nigeria.Patients and Methods: We retrospectively studied the case notes of all patients managed for ischemic priapism in the Ahmadu Bello University Teaching Hospital, Zaria, over a period of 10 years (2006–2015). The data extracted included   patients’ age, occupation, duration of painful penile erection, and previous episodes. Addition information including precipitating factors, hemoglobin genotype,  treatment, and complications was also retrieved. Data obtained were analyzed using SPSS version 20.Results: The records of a total of forty patients managed for priapism over the period under review were retrieved. Thirty‑three (82.5%) of these patients had an operative intervention. The mean age was 23.7 years with a range of 8–53 years. Sixty percent of patients were young adults in their third decade of life. The minimum duration of erection at presentation was 18 h and a maximum period of 10 days with a mean of 105.5 h (4 days). Thirty‑three patients (82.5%) had sickle cell anemia (HbSS).  Erectile dysfunction (ED) accounted for 60% of all forms of postpriapism complications. Five patients (12.5%) had residual tumescence from fibrosis, and three patients had recurrence outside the immediate postoperative period. Duration of symptoms before surgical intervention, SSA and previous episodes were the most important prognostic factors.Conclusion: Priapism is a disease of the young, mostly sickle cell anemic patients. Late presentation remains the norm in our environment, hence a higher incidence of ED. The distal penile shunt is an effective means of achieving detumescence even with failed conservative management. Favorable outcome is highly dependent on the duration of erection and early intervention.Keywords: Clinical presentation, ischemic priapism, prognostic factors, surgical treatment and outcom

Analysis of the Determinants, Characteristics and Management of Recurrent Urethral Strictures

Background: The presentation and management of the recurrent urethral stricture varies and depends largely on the initial treatment and the characteristics of the recurrent stricture. What are the likely determinants of recurrence? Patients and Methods: This is a retrospective review of all patients who had urethroplasties from January 2013 to December 2017 for anterior urethral strictures in our institution. Patients with a recurrence of the strictures were identified and reviewed, while patients with hypospadias and posterior urethral stenosis or contractures were excluded from the study. The etiology, length, site, and type of urethroplasties were evaluated as variables that may contribute to the recurrence of strictures using inferential statistics and logistic regression analysis. Time to recurrence was analyzed using the Kaplan–Meier method. Results: A total of 206 urethroplasties for anterior urethral strictures were evaluated with recurrence of strictures noted in 29 patients and a recurrence rate of 14.1%. Recurrence was higher in long-segment strictures, penobulbar strictures, and postinflammatory strictures. Pedicle flaps were used in 45% of the strictures that reoccurred. Using Chi-square, the length, site, of urethroplasties were statistically significant determinants of recurrence; however, only the site of stricture was found to be statistically significant following logistic regression analysis. The site of recurrence was in the bulbar urethra in 79% and the penile urethra in 21%. The choice of treatment of the recurrent strictures was anastomotic urethroplasty in 76.5%. The mean time to failure in this study was 13 months with a range of 6-120 months. Conclusion: In this study, the site of stricture was found to be the most determinant of stricture recurrence, with penobulbar strictures mostly implicated. Long-segment strictures were also noted to contribute to some extent in recurrence. These recurrent strictures were mostly short-segment strictures in the bulbar urethra which were amenable to excision and anastomosis to achieve cure
