Prostatic hyperplasia is the most frequent tumor in men older than 50 years of age. Bilateral hydronephrosis secondary to benign prostatic hypertrophy is a rare condition most often due to vesicoureteral reflux. Herein we report a case of a patient with bilateral hydronephrosis with distal ureter obstruction caused by detrusor hypertrophy due to prostatic hyperplasia, our analysis of the clinical data and a review of the relevant published literature.


We report a case of a 65-year-old Berber man with clinically significant storage, bladder-emptying symptoms and bilateral low back pain with renal biologic failure and bilateral ureterohydronephrosis, distal ureteral stenosis, detrusor hypertrophy and prostate hyperplasia without significant post-void residual urine volume visualized by abdominal sonography. The patient underwent bilateral JJ stent insertion with transurethral resection of the prostate. The patient was discharged 3 days after surgery without any obvious complications. At his 3-month follow-up examination, the JJ stent was removed and the patient had comfortable urination without renal failure.


This is an extremely rare condition that has important diagnostic considerations because of the possibility of comorbid severe obstructive uropathy and chronic renal failure.
