Abstract: Objective: To evaluate the effects of varicocele on sperm characteristics, on testicles and its responsibility in male fertility. Patients and Methods: The study took place in the National University Teaching Hospital Hubert Koutoukou Maga of Cotonou. It was a prospective study, from December 2015 to July 2016, which concerned 45 patients affected by the varicocele and seen for infertility. The duration of the infertility was 12 months or more, according to the definition. The studied parameters were the age, the profession, the deadline of the infertility, the type and the rank of the varicocele, the data of the ultrasound and the spermogram. Results: The average age of our patients was 35 years with a range of 20 and 56 years. The average duration of infertility was 3 years and 5 months. The pattern of consultation was a desire of paternity in 71.1% of cases. The testicular hypotrophy was found in 93.3% of cases at the right side and in 97.8% at the left side. The varicocele was bilateral at 82.2% of cases. The most frequent sperm abnormality was the oligoasthenoteratozoospermia found in 31.1% of cases. Conclusion: The varicocele is a male subject pathology. Its consequences on fertility are bad as well as on the volume and the capacity of the testicles to play its endocrine and exocrine function. The better choice is to start the treatment just when it is found in a man. The surgery seems to be the best solution to that important social problem.

Abstract: Most urological conditions are represented by male disorders. Analyzing certain epidemiological aspects of female urological disorders at the National University Teaching Hospital of Cotnou, will allow us objectively to have reliable data to optimize the urological management of women. Patients and Methods: This was a retrospective, analytical and descriptive study that was conducted at the CNHU-HKM over a 10-year period from January 2008 to December 2017 on the epidemiological aspects of female urological diseases from the study of patient records. The variable studied was: the age, the profession, the year of admission, the organ affected, and the type of pathology. The confidentiality of the data has been ensured. Results: Female urological disorders over 10 years accounted for 9.62% of all patients received in Urology Department. The age group greater than 50 years was the most common at 31.34%. Traders and housewives were the most numerous (39.93% and 14.55%). Bladder diseases were the most frequent (51.50), dominated by vesico-vaginal fistulas (29.85%). In addition to fistulas, tumoral affections were most prevalent at 27.99% followed by infectious diseases at 8.21%. The lithiasic affections were infrequent at 6.72%. Conclusion: Female urological conditions are infrequent but not negligible, dominated by vesico-vaginal fistulas and tumors in the context of developing countries. The specific evaluation of each pathology group can help optimize management.

Objective: To study the epidemiology and current trend in the management of urologic complications following obstetric and gynaecologic surgeries at CUUA University hospital of Cotonou. Patients and Methods: It was a retrospective study of patients referred with urologic complications following obstetric and gynaecological surgeries. The study took place at the Teaching Clinic of Urology Andrology at CNHU of Cotonou between April 1, 2008 and March 31, 2013. Results: Forty-one patients were studied. They represented 3.5% of people hospitalized at CUUA throughout the study period. The average age was 41 years swith range of 20 and 57 years. Twenty-one (51.2%) of them were married. Thirty patients (73.2%) were referred from a non-academichospital, while 7 patients (17.1%) were referred from academic hospital. Caesarean section was the primary gynecological surgery in 22 cases (53.7%) and hysterectomy in 19 cases (46.3%). Clinically, the pre- dominant symptoms were leakage of urine throughout the vagina and obstructive anuria with or without back pain. We found 31 cases of VVF, 5 cases of bilateral ligation of the ureters, 3 cases of unilateral ligation of the ureter, 1 ureteralinjury and 1 uretero-vaginal fistula. These complications were diagnosed postoperatively in 95.1% of cases. Surgeries done included VVF repair in 31 cases (75.6%), unilateral ureteral reimplantation in 4 cases (9.8%), removal of ligation of the ureters in 3 cases (7.3%), bilateral ureteral reimplantation for 2 cases (4.9%) and end-to-end anastomosisin 1 case (2.4%). The postoperative period was uneventful in 29 cases and we observed 7 cases of surgical site infection. The overall success rate was 87.8%. Conclusion: Urological complications following gynecologic surgeries managed at the urologic department of teaching hospital of Coto-nou had an even higher incidence. Early diagnosis especially during the operative procedure would save the patients’ serious complications and open surgery due to the lack of endo-urological facilities. The most important factor in prevention is good knowledge of pelvicanatomy and good knowledge of the surgical techniques of caesarean operation section and trans-abdominal hysterectomy.

Abstract: Aims: To evaluate the clinical stage at diagnosis of prostate cancer. Materials and Methods: This study was retrospective and?descriptive from January 2008 to June 2013. Patients who were diagnosed with prostate cancer wereinvolved and confirmed by clinical examination anatomopathological screening. They also realized a total serum PSA, a bladder-prostatic and abdominal ultrasound. Results: Average age was seventy years, ranging from fifty years to seventy years. The general status of our patients was satisfactory in 78% of cases. Main symptoms were dysuria and frequencyin 96% and 86%, respectively. Family past history of prostate cancer were found in 24% of cases. Twenty-three patients (43%) had a total serum PSA ≥ 100 ng/ml. Adenocarcinoma was the main histological type. Grades 1 and 4 were the most frequent. Thirty-three patients (66%) had a Gleasonscore betwen [2]-[6]. Forty-four patients (88%) had locally advanced and metastatic desease. The D’Amico score was identified in six patients but 3 and 2 patients were low risk and intermediate riskrespectively. Finally, 1 patient was high risk. Conclusion: Prostate cancer remains elderly man cancer. It was discovered in locally advanced and metastatic desease in this series. This diagnosis was late in the majority of cases.

Abstract: Introduction: Undescended testis is a genital pathology of pediatric age. But it is not rare that the diagnosis of this pathology is made in adults, especially in low income countries with management problems as Benin Republic. The purpose of this study was to describe the epidemiology and therapeutic aspects of this congenital malformation in adults, in HKM University Teaching Hospital of Cotonou. Material and Method: It was a retrospective, cross-sectional and descriptive study, conducted from January 1, 2007 to December 31, 2016. Patient files served as data collecting support. All the patients aged 16 years and older were included in this study, treated and followed in the urology clinic department for undescended testis. Results: Twenty-three files were selected. The most represented age group was 16 to 20 years of age. The average consultation time from the observation of the anomaly was 213.6 months. The vacuity of the scrotum was the main reason for consultation. The absence of an intra-scrotal testis was the most clinical finding. The testis was found in the inguinal canal in 15 patients. Surgical re-positioning testis in scrotal location had been conducted for all patients and the open surgery was the only modality. Orchiectomy was performed in presence of atrophic testis. Any complication was reported in postoperative time. Later, two retractions of the testis and two testicular hypotrophies were seen. Semen control (spermograms) revealed persistence of azoospermia in three patients and astheno-zoospermia in another. Conclusion: Cryptorchidism is a pathology of the child but can still be seen in adults in our context. The main reason for consultation is the vacuity of scrotum but also paternity desire. Surgical lowering is the rule. In adults, its main purpose is the surveillance for the easy and early detection of a testicular tumor.

Abstract: Introduction: The presence of an obstacle in upper urinary tract, threatens kidneys and therapeutic arsenal includes an ureterovesical reimplantation especially in the case of lower ureteral obstacles. Ureterovesical reimplantation (UVR) techniques are numerous with each of its advantages and disadvantages. In order to review indications, techniques and the outcomes of the ureterovesical reimplantation in our context of work, we made this study. Material and Method: It was a retrospective, transversal, descriptive and analytic study conducted over a period of 10 years, in the department of urology University Hospital Center Hubert Koutoukou Maga of Cotonou. Patients over 15 years of age who have had a ureterovesical relocation had been included. Results: Thirty-six files were selected. Ureterovesical relocations accounted for 1.8% of surgical procedures. The ligatures iatrogenic ureters and vesico-vaginal fistulas were the most frequently involved in 33.4% and 27.8% respectively. The ureterovesical reimplantation was performed without anti-reflux plasty at 36.1% of patients. The technique of Politano-Leadbetter had been most accomplished, in 82.6% of the cases in which anti-reflux plasty had been made. Suites had been simple in 63.9% of patients. Postoperative complications were dominated by parietal suppurations and vesicocutaneous fistulas in respectively 6 and 4 patients. Conclusion: Ureterovesical reimplantations are interventions that require from the urologist a perfect knowledge given their complexity and the emergency context in which one may be led to practice them. They answer to general principles that reduce operative morbidity.

Abstract: Purpose: To study the epidemiology and treatment modalities of urolithiasis at Urology Department of University Hospital of Cotonou. Materials and Methods: It was a retrospective and descriptive study over a 10 years period ranging from January 1st, 2004 to December 31st, 2013. One hundred and two patients who were hospitalized for symptomatic urolithiasis at the Urology Department of University Hospital of Cotonou were enrolled. Results: Hospital incidence of urolithiasis was 3.7%. Patients mean age was 39.6 years (extremes: 10 years to 73 years). Male to female ratio was 2.2. The main reason for consultation was renal colic for 81 patients (79.4%). Average duration of symptoms at presentation was 5 months (range: 1 day to 10 years). A total of 173 stones were identified with an average size of 12 mm (range: 1 mm to 95 mm). Calyceal stones were seen in 32.9% of cases, renal pelvis stones in 21.4% of cases, ureteral stones in 34.1% and bladder stones in 11.5% of cases. Open surgery was the main treatment for stones that could not be managed medically. 50.8% of patients underwent surgery with extraction of 116 stones. This represented 67.1% of all stones. 9 patients (8.8%) had expelled their stone during urination. The postoperative course was uneventful in 77.5% of cases. Conclusion: Modern treatment options for urolithiasis remain rudimentary in our health facilities. Open surgery is still the main stay of treatment in our countries with limited resources.

Abstract: The authors report 4 different cases of giant hydronephrosis in the urology department of the national university healthcare, CNHU HKM of Cotonou. The frequency of the items, the etiologies and the different treatments carried out were elucidated. The patients were all females. The hydronephrosis affected the left kidney. The most frequent etiology was pyelouretral junction syndrome seconded by obstructive nephrolithiasis in the upper urinary tract. One of the last etiologies was lower pole vascular plexus. Three nephrectomies and one K?SS-HEYNES-ANDERSON pyeloplasty were carried out. Conclusion: Giant hydronephrosis is a rare condition. The etiologies were organic-based and malformed. The therapeutic attitude adopted shows the interest of an antenatal diagnosis for early care.

Abstract: Objectives: To evaluate therapeutic and prognosis of Uretero-pelvic junction abnomalities. Methods: This article was retrospective and descriptive, covering a period of six months, running from January 1st to December 31st, 2013 and conducted?to evaluate therapeutic and prognosis of Uretero-pelvic junction abnormalities. Included criteria were all patients whose diagnosis was abnormalities of the uretero-pelvic junction and had been confirmed after para clinical explorations. The stricture of the junction after a first kidney surgery did not include. The Creatinine level has considered high from 15 mg/l. Results: The median age was 35 years old. Age groups (30 - 40) years old have predominated in 36.2%. A male predominance had been noted in 62.3% versus 37.7% women. The most affected occupation was the officials in 37.7% of cases. The main reason for consultation was lumbar pain in 97.1%. The high creatinine level has observed in 19 patients (27.5%). Sixty-one patients (88.41%) have been operated. An abstention has been observed in 7 patients (10.14%) and one patient died before the surgical issue in renal failure. The early post-operative course has been uneventful in 78.7% (48 cases) and complicated in 21.3% (21 cases). Conclusions: Open surgery tends to disappear at the expense of the endopyelotomy and laparoscopy which gives best results. However, it is still relevant.

Abstract: Con el objeto de evaluar la respuesta a la selección en tres poblaciones tropicales de maíz, mediante selección familial combinada alternante, se sembraron los sintéticos seleccionados en ensayos de rendimiento en los ciclos agrícolas oto o-invierno (ciclo A) y primavera - verano (ciclo B), en seis localidades de la Zona Costera del estado de Veracruz, durante los a os de 1988 a 1990. Se encontró una respuesta positiva a la selección en las tres poblaciones, en donde destacan los ciclos C6 y C3 de la Mezcla Tropical Blanca (P2) por el mayor rendimiento. La mayor respuesta a la selección, en promedio de los dos ciclos de prueba, fue observada en la población Tuxpe o planta baja (P1) (4.6 %), seguida de la P2 (3.6 %) y finalmente de la población la Posta (P3) (3.3 %). La mayor respuesta a la selección en el ciclo A fue observada en la P1 (5.5 %), y en el ciclo B fue en la P2 (4.2 %). En P1 se registró la mayor respuesta a la selección en el ciclo A, pero P2 y P3 mostraron mayor respuesta en el ciclo B.
