Introduction: To study the clinical, paraclinical, diagnostic aspects and manage patients with urolithiasis according to the available technical facilities in urology department of N'Djamena in Chad. Urolithiasis is defined as the presence of one or more stony concretions located at any level of a segment of the urinary tract: calyx, renal pelvis, ureters, bladder and urethra. Materials and Methods: This was a descriptive type of a prospective study over a period of 4 years, from January 2008 to December 2011, involving 233 patients with urolithiasis treated in the urology department. Clinical and paraclinical examinations were the basis for the selection of patients. Informed consent of patient or their parents (for minors) was obtained for the anonymous use of records and photographs for scientific aims. Results: Urolithiasis represented 5.72% (233/4072) of all urological pathologies. Male dominance was significant with a sex ratio of 4.5/1. The age group of 0 -10 years was the most affected with a staff of 67 (28.75%). The clinic was dominated by dysuria (44.63%), renal colic (33.91%) and hematuria (9.01%). The main anatomical location was bladder (62.23%). The management was essentially medical and surgical. We recorded 7 cases of death or post-interventional hospital mortality rate of 3%. Conclusion: Urolithiasis is a real public health problem in Chad. Due to the inadequacy of the technical platform, the management was based on the open surgery. Etiological research was impossible by lack of technical laboratory platform.

IntroductionLes traumatismes fermés de l’abdomen sont fréquents.MéthodesIl s’agissait d’une étude rétrospective sur 49 dossiers de patients opérés pour traumatisme fermé de l’abdomen en cinq ans à l’Hôpital General de Référence Nationale de N’Djaména au Tchad. Les paramètres épidémiologiques, cliniques et thérapeutiques étaient étudiés.RésultatsC’étaient 42 hommes et 7 femmes d’âge moyen de 21,3 ans. Les étiologies étaient: les accidents de la voie publique dans 61,2% des cas; les écroulements de mur (14,3%); les agressions (8,2%). Les traumatismes fermés de l’abdomen étaient plus fréquents au mois d’Août (14,28%) et Octobre (16,32%). Le délai d’admission à l’hôpital était de 6 à 12h dans 43% des cas. Le moyen d’évacuation des blessés était une voiture privée dans 85,7% des cas. Cliniquement, l’état hémodynamique était souvent stable (55,1%). L’imagerie médicale était dominée par la radiographie directe de l’abdomen (57,1%). Les lésions les plus observées ont été celles du grêle seul (16,32%) ou associées à celle de la vessie (8,16%), et de la rate (2,04%). La laparotomie était négative dans 6,12% des cas. La morbidité (12,2%) était dominée par les abcès de paroi. Le taux de décès était de 6,1%.ConclusionLes accidents de la voie publique sont la première cause de traumatismes fermés de l’abdomen. Le délai diagnostic et thérapeutique est important. Des mesures de sécurité routière devraient prévenir les accidents.

Introduction: Renal colic is a medico-surgical emergency in which complicated forms could progress to renal failure and nonfunctional kidney. The objective of our study is to describe the epidemiological, diagnostic and therapeutic aspects of renal colic at the urology department of the NGRH. Methods: This was a prospective study involving 101 patients followed up for renal colic. The study spanned from July 2015 to July 2016 at the urology department of the NGRH. Results: A total of 101 patients suffering from renal colic were enrolled in the study giving a prevalence of 5.1%. The mean age was 38.89 years with a standard deviation of 14.5 years and a sex ratio of 1:3. Flank or lumbar pain of crushing type (45.5%), constant and of severe intensity (61.4%) were the most frequent clinical characteristics. The plain abdominal radiography (Kidney-Ureter-Bladder) coupled with ultrasonography had a 100% sensitivity for the etiological diagnosis of renal colic. Urinary lithiasis was the most frequent cause with 73.3%. Uroculture revealed a urinary tract infection in 44 patients (43.6%). The most frequent germ isolated on the culture was Escherichia coli (27.7%). Renal function was abnormal in 34 patients (33.7%). Medical treatment was composed of analgesics, NSAIDs and antispasmodic representing 93.1%. Percutaneous nephrostomy was performed in 6.9%. Pyelolithotomy was the most frequently performed surgical procedure and was done in 11 patients that are 39.3%. Fifty seven patients (56.4%) got healed without sequelae; 6 cases (5.

Introduction: Retrocaval ureter is a rare congenital anomaly concerning the inferior vena cava and the ureter, where the infra-renal segment of the vena cava is in front of the ureter embryologically normal. This anomaly is more frequent in the male sex. Its symptoms are dominated by right lumbar pain, which is managed surgically as dictated by its intensity. Observations: The cases involved three male patients aged 42 years, 38 years and 39 years respectively. These patients had consulted for intermittent right lumbar pain similar to that of renal colic. The patients' general condition was satisfactory. Renal function was normal. Urinary tract ultrasound, IVU and scanning were the main imagery examinations used in diagnosing retrocaval ureter, confirmed by exploratory lumbotomy. Ureteral anastomosis in front of the vena cava was carried out in the 3 patients during simple surgical procedure that resulted in disappearance of the lumbar pain. Conclusion: Retrocaval ureter is a rare congenital malformation, often encountered in the male sex. Clinical symptoms are dominated by right lumbar pain similar to renal colic. Surgical treatment is dictated by the intensity of the pain.

Introduction: Describe the diagnostic approach and management of prostate cancer at the medico-surgical center of urology in Douala, Cameroon. Materials and methods: This was a descriptive retrospective study reviewing 100 patient's records suffering of prostate cancer from January 2011 to December 2015. The studied variables were clinical, paraclinical and therapeutic. Results: The mean age was 65 years with extrems of 50 and 85. Rectal examination was suggestive in 63 cases. 7 patients had a family history. The average PSA rate was 43.23 ng/ml. Histology has concluded to an adenocarcinoma in all patients. The gleason score was equal or greater than to 7 for 53 patients (53%). The extended assessment revealed distant metastasis for 43 patients. The treatment was: surveillance (n = 33), total laparoscopic radical prostatectomy (n = 24), surgical hormone therapy (n = 10), medical hormone therapy (n = 28) and chemotherapy coupled with hormone therapy (n = 5). Conclusion: Prostate cancer is common in Douala; its diagnosis is made late. Radical treatment is possible for localized cancers, hence the interest of early detection.
