OBJECTIVES The optimal prosthesis option for aortic valve replacement in adult patients<60 years of age with severe aortic stenosis (AS) remains controversial. The objective was to determine the long-term outcomes of the Ross procedure in this population. METHODS Between 1990 and 2013, 276 patients aged 18 years and above (mean 40.3±10.6) underwent an(More)
The hydraulic ileal valve, which we developed in 1975, ensures continence by adapting to 5 different urinary reservoirs. The valve is made by isolating a 14 cm. long intestinal loop with the mesentery. The isolated ileal segment then is folded inward on itself throughout its entire length. We performed 136 continent urostomies with this hydraulic valve. An(More)
The authors reports their experience of a large series of 1050 cases of vesico-vaginal fistulas recorded during 30 years and analyse their epidemiological, anatomo-clinical, and therapeutic aspects. Patients could be classified as a function of site of fistula into 3 types, according to the Benchekroun's classification: type I ureto-vaginal fistula (30%);(More)
Urogenital tuberculosis raises major diagnostic problems due to the frequently atypical and misleading clinical features. It is a serious disease as the lesions are often multifocal and extensive, requiring major surgical resection and urinary tract reconstruction. Prevention of this disease is based on generalization of BCG immunization and adequate(More)
The authors describe a case of enterovesical fistulas in a patient with Crohn's disease that presented exclusively as urinary symptoms manifesting as bladder tumor. Ultrasound examination showed a normal upper urinary tract and a bladder tumor. Cystoscopy examination revealed a bladder tumor at the retrotrigonal region without showing the fistula orifice.(More)
The authors report a series of 20 cases of vesicovaginal fistula (VVF) treated according to the Martius procedure. The mean age of the patients was 30 years (range: 20 to 37 years). All fistulas were secondary to obstetric trauma. The mean diameter of the fistula orifice was 4 cm. Fourteen fistulas were cervico-trigonal and 6 were urethro-cervico-trigonal.(More)
Symptomatology in thirty patients with hydatid cyst of kidney treated in the Urologic Clinic, UHC, Avicenne, Rabat, was florid (83% with pain and 43% with a mass in the flank) and sometimes specific (27% of cases). Associated hypertension was an exceptional finding. Preoperative diagnostic investigations included ultrasound and CT scan imaging, replacing(More)
Glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), alkaline phosphatase and acid phosphatase activities were measured in the serum and liver of both normal andEimeria-infected palm doves and rabbits. No significant increase in GOT activity was noticed in the serum of infected male or female palm doves. In contrast, GOT activity(More)
The concentrations of total serum proteins, total lipids, glucose, and liver glycogen were determined in normal as well asEimeria-infected palm doves. A highly significant increase in total serum protein concentration was observed in infected birds as compared with that seen in noninfected doves. There was an increase in total serum lipids subsequent to(More)
