Abstract
Introduction: The dilatation of the upper urinary tract, signs in the vast majority of cases the presence of a ureteral obstacle. The etiologies are diverse. Mali is a country where urinary schistosomiasis is endemic. Repeated infestation may result in long-term ureteropelastic dilatation secondary to stenotic sequelae. The objective is to study the causes of dilatations of the upper urinary tract. Materials and Methods: This is a prospective study of 12 months, from October 2010 to September 2011, performed in the urology department of Gabriel Toure University Hospital in Bamako. The parameters studied were: age, sex, reason for consultation, medical history, urinary analysis, etiological diagnosis, management, evaluation of renal failure. Result: In 12 months, we collected 50 cases of dilatations of the upper urinary tract representing 0.66% of all consultations. The average age of our patients was 35 years old. The sex ratio was 2.13 in favor of men. A history of urinary schistosomiasis was found in 25 patients or 50%. Low back pain was the most common reason for consultation, 76%. The renal and bladder ultrasonography performed in all 50 patients in our series found bilateral dilatation in 68% of patients and unilateral dilation in 32% of cases. Urinary tract infection with Escherichia coli was found in 53% of cases. Ureterovesical reimplantation was performed in 40% of cases. Conclusion: The dilatation of the upper urinary tract, consequence of an anatomical or functional obstruction, constitutes a rather frequent pathology and constituted 10% of the surgical acts of our service. Etiologies are diverse: congenital and acquired. Open surgery gives good results, but the introduction of innovative minimally invasive surgical technique is necessary.
Highlights
The dilatation of the upper urinary tract, signs in the vast majority of cases the presence of a ureteral obstacle
As Mali is part of the endemic bilharzia zone, repeated infestation can lead to long-term uretero-pyelocalyceal dilatation secondary to stenotic sequelae
These uretero-pyelocalyceal dilatations lay a threat to the patient who can progress to acute, chronic or terminal renal failure
Summary
The dilatation of the upper urinary tract, signs in the vast majority of cases the presence of a ureteral obstacle. The parameters studied were: age, sex, reason for consultation, medical history, urinary analysis, etiological diagnosis, management, evaluation of renal failure. This dilatation is discovered as part of a review of renal failure or low back pain. As Mali is part of the endemic bilharzia zone, repeated infestation can lead to long-term uretero-pyelocalyceal dilatation secondary to stenotic sequelae. Their evolutions without treatment result in the alteration of the renal function. These uretero-pyelocalyceal dilatations lay a threat to the patient who can progress to acute, chronic or terminal renal failure
