Objective: To compare the results of transvesical and retropubic prostatic adenomectomies at the Urology-Andrology Department of Conakry University Hospital. Methodology: This was a prospective multi-operator analytical study lasting 6 months. It included 70 patients operated on for benign prostatic hypertrophy (BPH), divided into 2 groups of 35 according to the retropubic or transvesical technique. The data was collected using a questionnaire and entered into the Epi info application. The analysis was initially descriptive and then univariate. To identify confounding factors, a multivariate analysis was performed. The application conditions of each test were checked before their application. A p-value Results: Upper adenomectomies represented 53.6% of surgeries performed for BPH. The average age was 73.2 years. The mean prostate volume was 117 ± 51.6 cc and the mean total PSA was 9.2 ± 11.4 ng/ml. The majority of patients had an ASA1 (60%) and ASA2 (37.1%) score. Spinal anesthesia, a double-current silicone probe with hinged hinge 22, and drainage of the prevesical space were carried out in all patients, i.e. 100%. The average overall blood loss was 229 ± 98.2 ml. It was lower in the group of patients operated via the retropubic route (187 ± 60.4 ml). The same was true for the duration of intervention (49.1 ± 7.17 vs 55.4 ± 7.9 min), the catheter wearing time (5.14 ± 0.97 vs 9.29 ± 2 .9 days) and the length of hospitalization (=6.26 ± 1.15 vs 12.1 ± 5.74 days). Conclusion: The retropubic technique has advantages over the transvesical one. These advantages are translated by a gain in the duration of the intervention, blood loss, catheter wearing time and length of hospitalization.

Introduction: Torsion of the spermatic cord is an emergency whose delay in treatment conditions the functional prognosis of the testicle. The aim of this study was to analyze the management of spermatic cord torsion in the Urology Andrology Department of the Ignace Deen National Hospital in Conakry. Material and methods: This was a ten-year retrospective descriptive study from January 1, 2012 to December 31, 2021. It involved all patients admitted for torsion of the spermatic cord, confirmed at surgical exploration. Results: We identified 21 cases of torsion of the spermatic cord. The mean age of the patients was 17.9 ± 4.4 years. The average consultation time was 19.2 ± 21.4 hours with extremes of [2 h and 98 h]. Only 6 patients (28.6%) consulted before the sixth hour. All patients presented with scrotal swelling. At scrototomy, all torsions were intravaginal with two turns of spiral in 13 cases and three turns in 8 cases. Orchiectomy followed by contralateral orchidopexy was performed in 6 cases. In the other cases, bilateral orchidopexy was performed after detorsion. The average hospital stay was 4.5 days. We recorded 4 cases of testicular atrophy after orchidopexy. Conclusion: Spermatic cord torsion is an infrequent emergency in our department. The delay in consultation remains the main predictive factor of testicular necrosis. Emergency exploratory scrotomy should be the rule.
