Prevalence and pattern of renal complications of uterine fibroids in a Teaching Hospital in Nigeria.

Abstract

Background: Symptomatic uterine fibroids causing obstructive nephropathy were thought to be uncommon, but recent prevalence studies showed otherwise. The aim of the study is to determine the prevalence of obstructive uropathy and nephropathy in patients with uterine leiomyoma.

Methodology: The study was a hospital-based cross-sectional retrospective study of 114 patients diagnosed with symptomatic uterine fibroids seen in the gynecology clinic of Lagos State University Teaching Hospital, Ikeja from February 2021 to June 2022.

Results: The overall prevalence of obstructive uropathy and nephropathy was 22.8% and 10.5% respectively. The average level of serum creatinine was 2.2 ± 1.9mg/dl with a creatinine range of 1.8 to 6.7mg dl. The average of the GFR among patients was 29.3 ± 13.4ml/min/1.73m² with a range of 9 - 54ml/min/1.73m². There is a positive association between uterine size and uropathy and subjects with uropathy are more likely to develop nephropathy. (CI 95% 3.281 - 108.670).

Conclusion: This study showed that prevalence of obstructive nephropathy in the patients with uterine leiomyomata is 10.5%. Uterine size and myoma diameter were positively associated with development of obstructive nephropathy.
