Retrograde Intrarenal Surgery for Partial Staghorn Calculus in Thoracic Kidney: Case Report

Abstract

Abstract Background Thoracic kidney (TK) presenting with symptomatic urolithiasis is a rare case scenario. Retrograde intrarenal surgery (RIRS) for calculus in TK is not reported in the literature. We report a case of partial staghorn calculus in TK managed by RIRS. Case presentation A young adult male presented with back pain and was found to have right TK and bilateral partial staghorn calculus. He also had right cryptorchidism with intraabdominally located testis. He underwent staged bilateral RIRS and laparoscopic right orchiectomy. Follow-up ultrasound imaging showed complete stone clearance in both kidneys. Conclusions RIRS is safe and effective treatment option, in the management of urolithiasis in TK. The anatomical abnormalities in TK did not play any hindrance role in the ureteral access, renal maneuverability of the flexible ureterorenoscope and subsequent drainage of the stone dust after RIRS.
