Management of Obstructive Renal Failure in Adults at the Sylvanus Olympio University Hospital

Abstract

Background: Obstructive nephropathies are a topical issue in urology and nephrology consultations, but no study has yet been conducted on the subject in our country. Objective: Describe the epidemiological, clinical, therapeutic and evolutionary profile of obstructive nephropathies at the Sylvanus Olympio University hospital of Togo. Method: It was a descriptive and cross-sectional study with a collection of retrospective data over a period of 08 years (2012-2019) which focused on obstructive nephropathies in the Urology-Andrology, Nephrology and Internal Medicine departments at the medical clinic of CHU SO. The diagnosis of obstructive nephropathy is retained on the basis of radiological and medical imaging results. Results: The study population included 131 patients. The annual hospital frequency was 2.84 cases for 100 admissions. The mean age was 56.72 ± 17.76 years. These patients were mostly male (72.52%). The most frequent age group was 60 - 80 years. Common symptoms at presentation were loin pain (45.75%) and dysuria (25.95%). The average length of probable course of the disease before hospitalization was 636.94 ± 258.88 days (21 months). The etiologies of obstructive nephropathy were largely dominated by prostatic tumors in half of the cases (45.80%). Among these patients, 121 have presented renal failure (92.36%). The average serum creatinine at admission was 59.01 ± 21.56 mg/l. Of the 121 patients with obstructive nephropathy presenting renal failure, 54 (44.63%) had decreased their serum creatinine at the output of more than 25%. The open surgery (54.20%) was the main treatment. There was an improvement in kidney function in patients who had a shorter duration of disease progression and who did not have a history of loin pain, oliguria and that the etiologies of the disease were not tumors. Tumoral etiologies, the presence of a history of high blood pressure, oedema of the lower members, oliguria, and a longer duration of disease progression and sex were factors associated with the occurrence of end-stage renal disease. Conclusion: Renal failure is the main complication of obstructive nephropathy in Togo, hence the importance of an early diagnosis for better care.
