Abstract

Spontaneous rupture of the renal fornix (SRF) is a rare condition, usually caused by acute upper urinary tract obstruction, most commonly from kidney stones. Its association with ureteropelvic junction obstruction (UPJO), whether congenital or acquired, is very uncommon. We report a case of a 29-year-old man with fever and right lumbar pain. Imaging showed a fornix rupture without stones, indicating possible UPJO. Emergency drainage with a double-J stent quickly improved his condition, followed by laparoscopic pyeloplasty, leading to full recovery. This case highlights the importance of timely management of UPJO to prevent serious complications like fornix rupture.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
