Introduction : Le cancer de la vessie représente le dixième cancer le plus fréquent dans le monde avec environ 573 000 nouveaux cas en 2020, affectant principalement les hommes. Bien que ce cancer métastase typiquement aux ganglions lymphatiques, aux poumons et aux os, les métastases cutanées constituent une manifestation exceptionnellement rare, avec une incidence estimée à seulement 0,84% des cas. Ces métastases peuvent se présenter simultanément avec le diagnostic primaire, après le traitement initial, ou plus rarement comme première manifestation de la maladie. Le diagnostic différentiel est complexe car ces lésions peuvent être confondues avec des infections cutanées courantes, nécessitant un examen histologique et immunohistochimique approfondi. Cas clinique : Nous rapportons le cas d'un homme de 55 ans qui a consulté pour une dysurie associée à une lésion cutanée sus-pubienne évoluant depuis trois semaines. Initialement prise pour un abcès fistulisé, l'analyse anatomopathologique de cette masse bourgeonnante nécrotique a révélé un carcinome épidermoïde infiltrant bien différencié et kératinisé. L'échographie a montré une masse vésicale de 54 mm avec dilatation pyélocalicielle bilatérale. Le décès précoce du patient n'a pas permis la réalisation d'un bilan d'extension complet ni d'une confirmation immunohistochimique définitive de l'origine vésicale de la métastase. Cette évolution rapidement fatale illustre le pronostic sévère de cette présentation métastatique. Conclusion : L'extension cutanée du cancer de la vessie est une manifestation clinique rare nécessitant une vigilance diagnostique accrue. Ce cas souligne l'importance d'un diagnostic précoce et d'un bilan d'extension systématique incluant l'imagerie en coupes et la confirmation immunohistochimique pour optimiser la prise en charge. Une approche multidisciplinaire impliquant urologues, dermatologues et anatomopathologistes est cruciale pour optimiser la prise en charge de cette condition au pronostic défavorable.

Self-insertion of foreign bodies into the urethra is an uncommon but significant clinical situation that urologists may encounter during their careers. It raises several questions, particularly regarding the mode of insertion. Such cases present a therapeutic challenge, as the removal of the object must be performed without causing trauma or injury to the bladder or urethra. Clinical examination, imaging studies, and, when necessary, psychosexual evaluation, are essential to establish an accurate diagnosis and offer the patient appropriate management. We report a 69-year-old male patient who self-inserted a pencil into his urethra and was managed in the urology department of the National Hospital Amirou Boubacar Diallo in Niamey.

Introduction: Genital fistulas communicate an element of the urinary system and an element of the genital system. They are a major public health problem. Our study took place at the National Reference Center for Obstetric Fistulas (CNRFO). Methodology: This was a retrospective and descriptive study covering a two-year period from January 1, 2023 to December 31, 2024. Results: A total of 23 cases of genital fistulas of iatrogenic origin were collected. The average age was 36.69 years. The most common genital fistula etiology was hysterectomy in 69.6% of cases. The main reason for consultation was dominated by urinary leakage through the vagina in 87% of cases. All patients had benefited from a standard biological check-up in 100% of the cases each. With 54.5% of cases, the low track was the most realized. Fistuloraphy was the most practiced technical gesture, 59% of cases. The evolution was favorable in 95.7% of cases. Conclusion: Genital fistulas of iatrogenic origin are becoming a relatively common complication of cesarean section and hysterectomy in developing countries including Niger. Its eradication must go through prevention, training in surgery based on the acquisition of sustainable skills.

Background and rationale: Urine drainage after renal secretion and excretion requires an unobstructed urinary tract. In the event of an obstruction, and depending on the etiology of the obstruction, endoscopic drainage of the urinary tract is indicated. This study aimed to identify the indications and assess the quality of life of patients who have undergone endoscopic drainage of the upper urinary tract at the Clinique Universitaire d'Urologie - Andrologie of the CNHU-HKM in Cotonou over the past five years. Patients and method: This was a descriptive, retrospective study of patients who underwent endoscopic drainage of the upper urinary tract (JJ stent assembly) at the CNHU-HKM University Urology-Andrology Clinic from January 1, 2018, and December 31, 2022. The English-language "ureteral stent symptom questionnaire (USSQ)" developed and validated by Joshi et al, then translated and validated in French in 2010, enabled us to assess the tolerance of JJ stents in our patients. Results: A total of 173 patients were selected, with an average age of 46. Males accounted for 64.61 % of cases. JJ catheterization was indicated in 51.44 % of cases (n=89), due to ureterohydronephrosis. Etiologies were dominated by lithiasis obstacles in 73.41 % of cases. Pain and discomfort associated with the presence of the JJ stent were found in 27.75 % of cases (n=48). Sexual activity was impeded by pain in 4 patients (8.0 %). Conclusion: The use of JJ stent is common practice in urology, but they are responsible for significant morbidity. In our study, the indication is dominated by renal colic complicating lithiasis. Studies aimed at assessing the quality of life of JJ stent patients remain a challenge, as they very often lead to subjective conclusions and are generally influenced by confounding variables such as age and comorbidities. A better understanding of the areas of daily life impacted by JJ stent use will enable us to better inform our patients, as well as develop new JJ stent models to improve their tolerability.

Background: Glandular cystitis is a metaplastic lesion of the bladder urothelium primarily affecting men. There are two types: typical glandular cystitis and intestinal glandular cystitis. Therefore, the definitive diagnosis relies on histopathology. The controversial theory surrounds the malignant degeneration of these lesions. Here, we present a case of florid glandulo-cystic cystitis of intestinal origin. Clinic observation: A 20-year-old man presented to the clinic with intermittent total hematuria associated with obstructive and irritative symptoms that had been ongoing for more than a year. In Histology examen, there was an absence of malignant tumor proliferation and signs indicative of typical inflammation: Florid glandulo-cystic cystitis of intestinal type. Conclusion: Intestinal glandular cystitis is a rare condition affecting primarily men and involving the bladder mucosa. Its symptoms are nonspecific and often go undiagnosed. Transurethral bladder resection remains the treatment of choice, but other therapeutic modalities, proven effective, should not be dismissed. The issue of malignant degeneration remains a controversial topic for debate, but the course of the disease is primarily marked by recurrences, necessitating cystoscopic monitoring.

Background: Penile fracture is a rare accident whose diagnosis relies on a stereotyped history and a physical examination. Early surgical intervention is recommended. In Africa, as well as in Benin, research on this pathology is limited due to likely underreporting, possibly linked to cultural factors. Objectives: This study aims to examine the epidemiological, clinical, therapeutic, and evolutionary aspects of penile fracture. Methods: It is a retrospective and descriptive study collecting records of patients treated and followed for penile fracture at the Urology Department of CNHU-HKM in Cotonou between January 2010 and March 2021. Results: Over the course of 10 years, 23 cases of penile fracture were identified, representing a frequency of 2.3 cases per year. The average age of patients was 35 years, with a predominance of married individuals (n=17). Coital misstep was the primary circumstance of occurrence (n=15). The cracking sound (n=14), pain (n=23), swelling of the penis (n=16), and detumescence (n=23) were the main clinical signs. The average time to medical intervention was 13 hours. Surgical treatment with a circumferential approach under the coronal ridge was employed for all patients. The average duration of hospitalization was 60 hours. The prevalence of erectile dysfunction was 8.7% (IIEF-5). Conclusion: Penile fracture is a rare traumatic emergency. Diagnosis is facilitated by a stereotyped clinical presentation. Early surgical intervention is the optimal treatment for a favorable functional outcome.

Wünderlich's syndrome is a rare clinical occurrence whose symptom is Lenk's triad: sudden lumbar pains, signs of collapse and mass lumbar.We report a case of Wünderlich's Syndrome, the first manifestation of renal clear cell carcinoma in a 63-year-old man.The emergency treatment was a total left nephrectomy.

Purpose: To describe genitourinary emergencies at the university hospital in cotonouMaterial and Methods: This was retrospective descriptive study covering a period of 6 years running January 1, 2011 to January 1, 2017. All patients aged at least 15 years regardless of the sex were involved. We did not involve in this study, patients under aged 15 years old who have supported by the Pediatric surgery department. All departments were concerned by the study: Emergency department, surgery, traumatology, medicine cardiology, nephrology, internal medicine, haematology, rheumatology, neurology, reanimation and gynecology departments. The following items were studied: age, sex, complaints, etiologies and emergencies kinds.Results: The average age of patients was 51.4 years old (15 years’ old-100 years old). Genitourinary emergencies were accounted for 5.4%. A male predominance was noted in 88.6% against 11.4% women. The sex ratio was 7.7. The 55% patients were referred against 45% were admitted. Over 6 year’s period on the study, 46 cases of genitourinary emergencies opinion were done in eleven departments Anesthesia-reanimation department predominance was noted in 32.61%. In emergency department we were seen 391 patients for genitourinary emergencies. The discovery circumstances were urine complete retention in 45.49% with 43.40% of non–traumatic urine complete retention against 2.09% urine complete retention for traumatic urinary tract following up by genitourinary trauma in 19.8%.Conclusion: Genitourinary emergencies are different group of pathologies or symptoms.

OBJECTIVES:To report a technique of percutaneous endoscopic nephropexy, using a polyglactin suture passed through the kidney, in patients with nephroptosis. PATIENTS AND METHODS:Four women presenting with symptomatic right nephroptosis underwent a percutaneous endoscopic nephropexy. An upper-pole calyx was accessed percutaneously and a 24-F working sheath was placed. Another needle access was made through a lower-pole calyx and a #2 polyglactin suture was passed into the renal pelvis. It was then pulled out through the upper-pole tract using the nephroscope. A retroperitoneoscopy was performed and the tip of the nephroscope was used to cause nephrolysis. After inserting the nephrostomy tube the polyglactin suture was passed into the subcutaneous tissue and then tied without too much tension, to avoid cutting the parenchyma. RESULTS:The operative duration was 33 min and the hospital stay after surgery was 3.5 days. The nephrostomy catheter was removed 5 days after surgery. There were no complications, especially no haemorrhagic, infectious, lithiasic or thoracic complications. The four patients were relieved of their initial symptoms, with a mean follow-up of 28 months. Ultrasonography and/or intravenous urography showed the kidney at a higher location with the patient standing. CONCLUSIONS:This technique combines the nephrostomy tract used in percutaneous techniques with the suture and nephrolysis used in laparoscopic techniques. Moreover, this procedure seems to be safe, with satisfactory anatomical and clinical results and a lower morbidity. However, a larger series will be necessary to establish its long-term morbidity and success rate.

We report a new technique of percutaneous endoscopic nephropexy for the treatment of symptomatic nephroptosis.

The simultaneous presence of primary carcinomas in the same patient is uncommon and synchronous primary tumors involving the kidney and pancreas are extremely rare. There are a few reports in the English literature of synchronous primary malignancies of the kidney and pancreas. We present a 62-year-old man who had weight loss of 9 kg and epigastric pain. Findings showed a Furhman grade II renal papillary carcinoma confined to the kidney and a synchronous well differentiated pancreatic ductal adenocarcinoma.

Objective. To assess prospectively the results of percutaneous sclerotherapy with povidone-iodine of symptomatic renal cysts in adults.Methods. Fifty two patients were included in this study from august. 2004 to november 2006. The operative indication was: pain (41 cases), urinary tract compression (8 cases), and very large cyst (3 cases). The preoperative assessment (site and dimensions of the cyst) always included ultrasonography. CT scan, for morphological assessment, was performed in 39 cases.Results. The mean age of patients was 63 years (47 - 75 years). The mean diameter was 76 mm. The cysts were punctured mail the cases directly under local anaesthesia and guided by sonography. The procedure was very well tolerated in every case, with external drainage for 72 hours. Clinical regression was complete in 48 cases (92%), with total ultrasonographic disappearing of the cysts in 31 cases (60%) with 2 mean follow-up of 14 months (3-29 months).Conclusion. Percutaneous sclerotherapy with povidone-iodine is a safe, effective and reproducible treatment of symptomatic renal cysts in adults.

L’adénome métanéphrique du rein est une tumeur épithéliale bénigne rare. Son diagnostic est exclusivement histologique. Le diagnostic différentiel se fait essentiellement avec le néphroblastome et le carcinome papillaire à cellules rénales. L’étude cytogénétique apporte des éléments importants pour différencier entre ces trois entités histologiques. L’adénome métanéphrique bilatéral est exceptionnel (pour autant que nous sachions un seul cas a été rapporté dans la littérature) et pose un problème de diagnostic différentiel avec le cancer rénal bilatéral. Nous rapportons une nouvelle observation de cette affection rare chez un patient âgé de 64 ans.
