Introduction: Urolithiasis is a very common pathology in the world. Its epidemiological profile varies from one region to another. In Africa in general and in the Congo in particular, it seems to be unknown. Objective: To determine the sociodemographic, diagnostic, therapeutic and evolutionary paraclinical parameters of 167 adult patients with urolithiasis. Patients and Methods: Cross-sectional, descriptive, retrospective study conducted in the urology department of Brazzaville University Hospital over a period of five years. We studied sociodemographic, therapeutic and evolutive. Results: During the study period 167 patients were treated for urolithiasis out of 2236 patients, a hospital frequency of 7.46%. The sex ratio M/F was 1.49. The average age of the patients was 42.05 years. They were overweight and/or obese in 53% of cases. Workers accounted for 46.53% of cases, with a low socio-economic level (42.5%) and a lower level of education (68.31%). There was a high percentage of complications, dominated by hydronephrosis (66.33%) and urinary tract infection (59.4%). The treatment was surgical in the majority of cases or 74.8%. Thirty-three patients had a lithiasis recurrence, a frequency of 19.7%. Conclusion: Urolithiasis is common. Being overweight is the most found risk factor. Lithiasis recurrence affects nearly one in five patients.

Goal: To evaluate the results and complications of open pyeloplasty according to Anderson-Hynestechnic. Patients and Methods: We conducted a retrospective study from 2000 to 2014. The study included 36 cases of opening the ureteropyelic junction operated pit syndrome according to Anderson-Hynes technique. Results: Lumbotomy was used in all patients. A pelvic pyelolithotomy for lithiasis was performed in two patients (5.5%) and unwinding of a lower polar pedicle in 3 cases (8.3%). The average duration of response was 119 ± 15 min. The average length of hospital stay was 11.2 ± 3 days. Patients were followed for a mean of 10 months. Thirty-five patients were asymptomatic and in one case lower back pain persisted. IVU to 6 months showed a permeable junction in 97.2% of cases. Seven patients (19.4%) had short-term complications. Ureteropelvic stenosis was the only complication in the medium and long term in one case (2.8%). The success rate of the Pyeloplasty was 97.2%. Conclusion: The open pyeloplasty as Anderson-Hynes remains the treatment of choice in our context SJPU with great results. The indications tend to decrease in favor of laparoscopic pyeloplasty.

Background: Priapism is defined as a prolonged and painful erection that persists beyond or is unrelated to sexual stimulation. Its frequency is high in sickle cell patients in our regions. Despite being a urological emergency, many patients are diagnosed at a late stage, increasing their risk of sequelae. In this article, we assessed the management of priapism in our department, with the aim of improving our daily clinical practices. Patients and Methods: We conducted a monocentric retrospective descriptive study from January 2005 to December 2020. All patients admitted and treated for priapism in our emergency department during the study period were included. The following variables were considered: age, sex, etiology, consultation delay, treatment type and outcomes. A follow-up visit was scheduled once at 1, 6 and 12 months post-treatment and the erectile function was evaluated during this visit. Results: In total 97 patients were treated during the study period. Priapism represented the 4th urological emergency after urinary retention, renal colic and hematuria. The mean age was 23.63 ± 11.5 years old. Sickle cell disease was observed in 59.8% of patients. Sixteen patients (16.50%) who consulted within 12 hours of priapism onset were successfully treated by oral or injectable etilefrine. Forty-three patients (44.33%) who consulted between 12 and 36 hours were successfully treated using distal spongio-cavernous fistula. After treatment, detumescence was obtained in 86 patients (88.66%). Eleven patients (11.34%), who consulted after the 36th hour, developed cavernous fibrosis with subsequent erectile dysfunction. Conclusion: Priapism represents the 4th cause of admission at our emergency department. Sickle cell disease was the main cause of ischemic priapism in our context. One patient in 2 consulted after 36 hours following the onset of symptoms. Medical treatment was effect

Introduction: Testicular cancer accounts for 5% of urological tumors, predominantly affecting young men. The aim of our study was to report the diagnostic and evolutionary aspects of testicular cancer cases treated in our center. Patients and Methods: A retrospective study conducted over a 15-year period involving 12 patients treated for testicular cancer at the University Hospital of Brazzaville. Results: The median age was 31 years (range 11 to 49 years), with a median consultation delay of 10.6 months (range 3 to 27 months). Scrotal mass was the most common reason for consultation. Cancer was bilateral in two patients. Two patients were admitted with metastatic disease. Histopathological examination favored germ cell tumors in 7 cases, two cases of non-Hodgkin’s malignant lymphoma, and one case of epididymo-testicular adenocarcinoma. Adjuvant chemotherapy resulted in complete remission in patients with germ cell tumors. However, neoadjuvant chemotherapy was not effective in patients admitted with advanced-stage disease. Conclusion: Testicular cancer is a rare condition that is curable in the majority of cases, but its management is often complicated in our setting due to delayed diagnosis caused by taboos surrounding genital organ pathologies.

Background: The aim of this study was to evaluate the outcomes of stricture treatment using endoscopic internal urethrotomy in the male urethra. Patients and Methods: We conducted a retrospective study from 2012 to 2017 at the Urology and Andrology Department of the University Hospital in Brazzaville, Congo. Medical records of 30 patients who underwent endoscopic internal urethrotomy for urethral stricture were analyzed. We studied the following variables: frequency of urethral stricture, age of patient, onset, cause and location of urethral stricture, duration of bladder catheterization, duration of hospitalization, and postoperative complications. The treatment outcome was assessed after a follow-up of 2.6 years (extreme: 2 and 4 years). Outcomes were considered successful or good when the patients had a normal urine flow and an unobstructed urethra at the Retrograde Urethrogram (RUG). Results: The mean age was 47.5 ± 9.7 years (range: 17 to 83 years). Dysuria was the most common symptom reported. We found that urethral stricture was mostly caused by infectious diseases (20 patients). The urethral stricture was located at the membranous urethra in 4 patients, the bulbar urethra in 25 patients, and the penile urethra in 1 patient. The mean duration of the bladder catheterization was 2.3 days. Hospitalization duration was 36 hours. We observed the following complications: urethrorrhagia in 3 patients, acute orchiepididymitis. We achieved good results in 23 patients. Conclusion: In our context where the practice of endoscopic internal urethrotomy is recent, it provides satisfactory results for the treatment of short urethral male stricture.

Emphysematous cystitis is a rare complication of lower urinary tract infection whose prognosis is conditioned by the delay in treatment. The predisposition of diabetic patients to urinary infections caused by gas-producing bacteria is considered one of the most common factors in the occurrence of emphysematous cystitis. The currently recommended diagnostic test is CT scanning, which has definite value in assessing gas accumulation in the bladder wall and lumen. The authors report the observations of two patients aged 68 and 80 who were treated for emphysematous cystitis complicating diabetes mellitus. The evolution was favorable under treatment with antibiotic therapy, insulin therapy and bladder drainage.

Introduction: Urological emergencies play a significant role in the medical and surgical activity of a urology department. The objective of this study was to determine the hospital prevalence of urological emergencies at the University Hospital of Brazzaville (CHUB), identify the different pathologies requiring urgent care, and list the various therapeutic methods. Patients and methods: A retrospective study of patients admitted to the medical and surgical emergencies department of CHUB over a 5-year period. Patient records admitted and treated for a urological emergency were included. The variables studied were the frequency of urological emergencies, patient age at admission, gender, nature of the emergency, and various therapeutic options. Results: Urological emergencies accounted for 4.3% of all medical and surgical emergencies. The mean age was 57 ± 28 years with a range of 3 to 93 years. The male-to-female ratio was 7.1. The most common conditions were urinary retention (54.67%), hematuria (17.20%), and renal colic (8.13%). Therapeutically, surgical urinary drainage was dominated by cystostomy. Conclusion: Urological emergencies are infrequent at the University Hospital of Brazzaville. Their management is often delayed.
