Prostatic Cavity Stones Following Cystolitholapaxy with TURP: A Rare Postoperative Complication

BackgroundProstatic cavity stones, also termed utricular stones, are extremely uncommon complications that may arise after combined cystolitholapaxy and transurethral resection of the prostate (TURP).Such cases remain scarcely described in the literature.We report a unique presentation of residual stones forming within the prostatic cavity following this combined procedure. Case PresentationA 55-year-old man with a long-standing history of recurrent nephrolithiasis and multiple urological interventions presented with persistent lower urinary tract symptoms (LUTS) despite undergoing cystolitholapaxy with partial TURP.Follow-up imaging revealed residual calculi lodged within the resection cavity of the prostate.The patient experienced recurrent urinary retention and dysuria requiring further interventions.This illustrates a rare but important complication of combined procedures. ConclusionFormation of prostatic cavity stones post-TURP and cystolitholapaxy is exceptionally rare.Clinicians should remain vigilant for atypical postoperative symptoms, and careful evacuation of stone fragments during surgery is critical to prevention.
