Obstructive uropathy due to uretero-inguinal hernia: An uncommon occurrence
A 67-year-old obese man was referred for further investigation following an episode of sudden - onset left-sided loin pain that had lasted for 6 h and then resolved spontaneously. He had type 2 diabetes mellitus, but no other relevant past medical history. Physical examination revealed a large left - sided irreducible, non-tender inguino-scrotal hernia, and laboratory investigation, including serum creatinine was within normal limits. An ultrasound scan of his renal tract revealed left-sided hydronephrosis, and a subsequent computed tomography scan showed left-sided hydronephrosis with a dilated ureter that was seen to enter the large inguino-scrotal hernia [Figures and ]. It then took a path back out of the hernia where it became non-dilated and inserted into the bladder in its usual position.\nA subsequent dimercaptosuccinic acid (DMSA) scan confirmed reduced function of the affected kidney, contributing 35% to overall renal function and hence he underwent a mesh repair of this hernia with careful dissection of the ureter from the hernial sac and his post-operative recovery was uneventful.
