ABSTRACT: Purpose: To study the epidemiology and
treatment modalities of urolithiasis at Urology Department of University
Hospital of Cotonou. Materials and Methods: It was a retrospective and
descriptive study over a 10 years period ranging from January 1st, 2004 to
December 31st, 2013. One hundred and two patients who were hospitalized for
symptomatic urolithiasis at the Urology Department of University Hospital of
Cotonou were enrolled. Results: Hospital incidence of urolithiasis was 3.7%.
Patients mean age was 39.6 years (extremes: 10 years to 73 years). Male to
female ratio was 2.2. The main reason for consultation was renal colic for 81
patients (79.4%). Average duration of symptoms at presentation was 5 months
(range: 1 day to 10 years). A total of 173 stones were identified with an
average size of 12 mm (range: 1 mm to 95 mm). Calyceal stones were seen in
32.9% of cases, renal pelvis stones in 21.4% of cases, ureteral stones in 34.1%
and bladder stones in 11.5% of cases. Open surgery was the main treatment for stones
that could not be managed medically. 50.8% of patients underwent surgery with
extraction of 116 stones. This represented 67.1% of all stones. 9 patients
(8.8%) had expelled their stone during urination. The postoperative course was
uneventful in 77.5% of cases. Conclusion: Modern treatment options for
urolithiasis remain rudimentary in our health facilities. Open surgery is still
the main stay of treatment in our countries with limited resources.
