Male urethral diverticulum uncommon entity: Our experience

Area of Science:

• Urology
• Surgical Innovation

Background:

• Male urethral diverticulum (UD) is a rare condition, with congenital forms being even less common.
• UDs can be congenital, resulting from urethral fold closure defects, or acquired, secondary to strictures, infections, trauma, or prior surgeries.

Observation:

• This report details three male cases: two acquired UDs and one congenital UD.
• Case 1 involved a large proximal bulbar UD with distal stricture, managed with surgical repair and flap urethroplasty.
• Case 2 presented with a bulbar UD mimicking an anterior urethral valve, treated endoscopically with satisfactory outcomes.
• Case 3 had a proximal bulbar UD with incontinence post-stone surgery, managed with excision and conservative measures.

Findings:

• Retrograde urethrogram (RGU) and micturating cystourethrogram (MCU) are key diagnostic tools for characterizing UDs.
• Urethral diverticulectomy combined with urethral reconstruction is the standard treatment.
• Individualized management is crucial, with surgical modifications and innovative techniques, such as using diverticular flaps, proving beneficial.

Implications:

• This study highlights the rarity and diverse presentations of male urethral diverticula.
• It emphasizes the importance of tailored surgical strategies and the potential for innovative reconstructive techniques in managing UD.
• Further research into optimal surgical techniques for congenital and acquired male UDs is warranted.
