Primary squamous cell carcinoma of the kidney in southern Senegal (Ziguinchor): case report and review of the literature.

The kidney's primary squamous cell carcinoma is a rare tumor, representing 0.5-0.8% of malignant renal tumors and 4% of upper urinary tract tumors. This pathology often occurs after a long past history of renal lithiasis and repeated untreated or poorly treated urinary tract infections. The delay in diagnosis resulting from an insidious symptomatology, without specific signs, often leads to a pejorative development, especially in poor countries. A seventy-nine-year-old Senegalese woman, with no past history of lithiasis nor recurrent urinary tract infection and urinary schistosomiasis, was received for a recurrent total hematuria associated with left lumbar pain. Clinical examination revealed a mobile tender left lumbar mass, with lumbar contact and renal sloshing. The left renal tumor´s diagnosis was retained on clinical and scannographic arguments, justifying an enlarged left total nephrectomy, by laparotomy. The anatomopathological examination of the surgical sample made it possible to make the diagnosis of primary invasive squamous cell carcinoma of the left kidney and to find foci of carcinoma in-situ on squamous metaplasia in the calyxes. Unlike the typical case of primary squamous cell carcinoma of the kidney, our patient did not have a long past history of renal lithiasis nor untreated or poorly treated recurrent urinary tract infections and urinary schistosomiasis. Primary squamous cell carcinoma of the kidney may not be related to a past history of recurrent urinary tract infections and lithiasis, but to any other cause of squamous metaplasia of the urothelium. Surgery remains the best option for this entity.

[Results of two-level urethroplasty according to Bengt Johanson for complex urethral strictures in adults]. / Resultats de l'uretroplastie en deux temps selon Bengt Johanson pour les stenoses uretrales complexes de l'adulte.

AIM: to evaluate the results of two-level urethroplasty in the treatment of complex urethral strictures in our clinical center. PATIENTS AND METHOD: Thiswas a retrospective cross sectional study from January 2012 to September 2015 in our clinical center. Patients operated according to Bengt Johanson technique were included. The parameters studied were age, the urological history, consultation reasons, duration of evolution, stenosis characteristics and treatment outcomes. RESULTS: twelve patients were enrolled in our study. The mean age was 48 ± 20 years. The main reason consultation reason is urine retention. The mean duration of evolution was 30 ± 25 months. The most common etiology identified was scleroinflammatory one . All the patients already had at least one medical background. The physical examination showed a periurethral gangue in 10 patients. The mean length of the urethral stricture was 6.3 ± 2.2 cm. After an average follow-up of 3.8 ± 2.3 months; the treatment outcomes were considered satisfactory in 8 patients and bad in 4 patients. CONCLUSION: Bengt Johanson's two level urethoplasty gives good outcomes in the treatment of complex urethral strictures.

[Outcomes of radical prostatectomy in patients with prostate cancer at the Aristide Le Dantec University Hospital]. / La prostatectomie radicale: résultats carcinologiques au Centre Hospitalier Universitaire Aristide Le Dantec.

The purpose of this study was to assess outcomes of radical prostatectomy in patients with prostate cancer. We conducted a retrospective single-center study in the Department of Urology and Andrology at the Aristide Le Dantec Hospital in Dakar from June 1, 2010 to May 31, 2016. We collected data of 60 patients undergoing radical retropubic prostatectomy associated with dissection of the iliac and obturator nodes. After radical prostatectomy, prostate specific antigen (PSA) levels were undetectable (<0.1 ng/mL) in 20 patients (33.3%). Eleven patients (18.3%), who had biochemical relapse, received complementary hormone therapy. Patients achieved a response after initiation of treatment, and total PSA became undetectable again after an 8-month follow-up period. Mean overall survival was 17.5 months, with a median of 9.49. Cumulative overall survival rates at 1 year, 3 years and 4 years were 42.4, 13.6 and 6.8%, respectively. Mean relapse-free survival was 17.3 months, with a median biochemical relapse-free survival of eleven (11) months. The mean duration of specific survival was 8.1 months, with a median of 3 months. Seven patients had positive resection margins (11.6%). Four patients had lymph node involvement. Radical prostatectomy, suggested in some patients with prostate cancer in our practice, has been shown to be an effective therapeutic method leading to good outcomes.

Unusual Presentation of Priapism Associated with Acute and Chronic Myeloid Leukemia in Two Patients: Emergency Management.

Priapism is a rare urological emergency. It is rarely a telltale sign of myeloid leukemia. We report two cases of acute myeloid leukemia in a child and chronic myeloid leukemia in a young adult presenting with priapism. Puncture irrigation of the corpora cavernosa followed by systemic treatment to lower the hyperviscosity of the blood due to leukemia provided optimal outcome. Prompt emergency management is required to lower the complication of erectile dysfunction.

Impact of tumor cytoreduction in metastatic prostate cancer.

Objective: To assess the impact of tumor cytoreduction on cancer outcomes and patient survival in metastatic prostate cancer. Patients and methods: It is a prospective study spanning a two-year period between October 1st 2015 and March 31st 2017. We enrolled 102 cases of metastatic hormone-sensitive prostate cancer. Fifty-seven (57) patients had exclusively androgen deprivation therapy (ADT) (group 1) and 45 had, in addition, an open prostatectomy or Transurethral resection of the Prostate (group 2). We compared both groups using the total PSA nadir, the time to PSA nadir, the overall survival (OS), and the progression-free survival (PFS). Results: The average nadir PSA was lower for the tumor cytoreduction group (16.8±1.6 ng/mL (0.01-193.5) versus 110.7±17.9 ng/mL (0.01-1379)). Median time to PSA nadir was shorter in patients in the ADT only group (8 months vs 3 months (p=0.025)). The OS was shorter in patients treated with ADT only compared to the tumor cytoreduction group (median 14 months vs 24 months, respectively (p=0.03)). Similarly, tumor cytoreduction had a positive impact on patient progression (median PFS 20 months (group 1) vs 43 months (group 2)). Conclusion: Tumor cytoreduction has a positive impact on the oncological results and the survival of patients under ADT.

[Penile strangulation: about two patients living in rural areas]. / Strangulation du pénis: à propos de deux cas en milieu rural.

Penile strangulation is a clinical condition requiring emergency management. Several metallic or non-metallic objects can be placed around the penis to improve sexual performance or for auto-erotic purposes. We report the case of two schizophrenic patients aged 25 and 33years hospitalized in the Emergency Department due to penile strangulation by metal ring. The ring was placed at the level of the glans foreskin groove 3 days before in one case and at the level of the root of penis 2 days before in the other. There was no urinary disorder in both patients. Ring ablation was performed with taxis under local anesthesia in one case and under sedation followed by double ring section using an electric saw in the other case.

Renal cell carcinoma with MiTF/TFE3 translocation in children: report of a case at the stage of lymph node involvement.

Renal cell carcinoma (RCC) is rare in children. Unlike nephroblastoma, however, it does not respond well to chemoradiotherapy. Its treatment is therefore based on surgical removal of the tumour. However, lymphadenectomy for RCC is controversial, and its prognosis is unclear. The authors report a case of RCC with MiTF/TFE3 translocation at the stage of lymph node involvement without metastasis in a boy of age 12, who was treated with radical nephrectomy and limited lymphadenectomy. This tumour constitutes a newly individualised entity in the World Health Organization's 2004 classification. Eighteen months after the operation, the patient was presented with no sign of recurrence. This case aids in showing that lymph node involvement in RCC with translocation in children is not associated with a poor prognosis and that lymphadenectomy during surgery for enlarged nephrectomy is essential.

Etiology and current clinical characteristics of male urethral stricture disease: experience from a public teaching hospital in Senegal.

OBJECTIVE: To identify the etiology and current clinical characteristics of male urethral stricture disease (USD) in Senegal. PATIENTS AND METHODS: A retrospective and mono-centric study over a 10-year period (between January 1999 and December 2008) was carried out and included all male patients with USD admitted to the Urology Department of Aristide Le-Dantec Hospital (Dakar). RESULTS: We recorded 414 USD cases. The maximum annual incidence was observed in 2004, and from then, the incidence tended to decrease gradually. The mean age of patients was 43.7 ± 19.6 years (1-89 years), and 43% of patients were younger than 40 years old. The mean time from symptoms onset to the consultation was 20.1 ± 24.9 months (1-120 months). Most patients (42.2%) were admitted because they suffered dysuria. In 57.8% of patients, USD was diagnosed with complications. The most common site of stricture was at the bulbar urethra (72.7%). The length of the urethral stricture was smaller than 1 cm in 59.6% of patients, between 1 and 3 cm in 28.5% and between 3 and 5 cm in 7.7%. The stricture was longer than 5 cm in eight patients and was staged (multifocal) in nine patients. The etiology of urethral stricture was infectious in 63% of patients, traumatic in 13.7% and iatrogenic in 8.2%. The etiology was not identified in 14.9% of cases. The infectious etiology was urethritis in 259 cases and urogenital schistosomiasis in 12 cases. A study of the etiology according to stricture site showed that bulbar USD was infectious in 77.7% of cases and that all membranous USD cases were traumatic. CONCLUSION: Male urethral stricture in Senegal is often a sequela of gonococcal urethritis and is frequently detected because of infectious complications such as gangrene of the genitalia or urinary tract infections. Its prevention in this geographical region thus requires fighting against sexually transmitted infections and treating appropriately and effectively all urethritis.
