[Large urethral stones: a case report]

Area of Science:

• Urology
• Surgical Innovation
• Medical Case Study

Background:

• Large urethral stones, particularly in the penile urethra, present significant clinical challenges.
• Existing treatment options may be limited for calculi of substantial size (e.g., 5 cm).
• Complex cases necessitate tailored, multi-stage interventions for successful outcomes.

Purpose of the Study:

• To present a clinical observation of a patient with extensive penile urethral stones.
• To detail a successful three-stage surgical treatment protocol for large urethral calculi.
• To highlight the restoration of normal urinary function post-intervention.

Main Methods:

• Stage 1: Urinary bladder drainage via cystostomy.
• Stage 2: Urethrotomy for stone removal and creation of a double-barreled fistula.
• Stage 3: Anastomotic urethroplasty to reconstruct the urethra.

Main Results:

• The three-stage surgical approach effectively addressed the 5 cm penile urethral stones.
• Successful removal of calculi and reconstruction of the urethra were achieved.
• Normal urination was restored after the removal of the cystostomy drainage tube.

Conclusions:

• A staged surgical strategy, including urethrotomy and urethroplasty, is effective for managing large penile urethral stones.
• This case demonstrates the feasibility and success of complex reconstructive surgery for severe urethral lithiasis.
• Restoration of normal voiding function is achievable even with extensive urethral stone burden.
