Background: Benign Prostatic Hyperplasia (BPH) is a disease of the elderly. Some of the patients with this pathology could develop renal impairment due to the direct effect of obstruction or as a result of intrinsic renal disease. This study aimed to determine the burden and associations of obstructive uropathy and intrinsic renal disease in patients with benign prostatic obstruction in a university teaching hospital in Nigeria. Methods: This was a retrospective study of patients with BPH in our center. Glomerular Filtration Rate (GFR) was calculated and the severity of renal disease computed. Patients were classified as normal or those with obstructive uropathy and intrinsic renal disease. Patients’ age, diabetes mellitus presence and treatment given were also documented. Results: Obstructive uropathy and intrinsic renal disease occurred in 14 (15.1%) and 12 (12.9%) of the patients respectively. Nephropathy in the setting of obstruction occurred in four (4.3%) of the patients while the GFR was at stage 2 in obstructive uropathy patients who did not have renal impairment. Eight (10.4%) of the patients without nephropathy had diabetes mellitus. There was a significant inverse relationship between the age of presentation and the GFR (P = 0.001, odds ratio = −1.129). Initial urinary drainage delayed definitive surgery in all patients with obstructive nephropathy. Conclusion: The burden of nephropathy in BPH patients is quite considerable. A proportion of those without renal impairment harbour diabetes mellitus which could rapidly tilt obstructive uropathy patients into renal failure.
