Giant urethral calculus in anterior urethral diverticulum: a case report

Abstract

Background In this case report, giant calculus in the urethral diverticulum was found through ureteroscopy investigation, the pneumatic lithotripsy combined with ultrasound lithotripsy (PLCUL) was successfully performed to break down this rare and giant urethral calculus in the diverticulum without open surgery. Case presentation A 82-year-old male presented to the urology department, complaining of frequent urination and dysuria. One giant, dark brown stone (6.5 × 6 × 5.5 cm) was revealed in the diverticulum of the anterior urethra using combination of local ultrasound, pelvic Computer Tomography (CT) and Magnetic Resonance Imaging (MRI). The stone was then successfully broken down via the PLCUL, and the emptied anterior urethral diverticulum was left untreated. In the 18 months’ follow-up, no new calculus was found in urethral tract, anterior diverticula became gradually smaller, eventually disappeared. Conclusion In the treatment of giant calculus in the urethral diverticulum, this case report provides an effective method of lithotripsy in the clinical trials.

Acquired Urethrocutaneous Fistula in Children: Case Series of Unusual Presentations of a Usual Condition

“…An intensive search of adult literature revealed only five cases of urethral calculus with fistulae[ 2 3 4 ] and a few reported cases of urethral calculi in the anterior urethral diverticulum. [ 10 , 11 ] A large calculus in the bladder following bladder closure in a child with exstrophy bladder has been reported in a pediatric patient. [ 12 ] Clinical symptoms would depend on the patient’s age and the presence and associated severity of the urethral obstruction.…”

A Large Anterior Urethral Calculus Presenting as Urethrocutaneous Fistula

“…It can cause symptoms of bladder outlet obstruction and proximal hydroureteronephrosis, which if unnoticed can lead to renal insufficiency. Urethral stone can be associated with urethral stricture, urethrocutaneous fistula or urethral diverticulum (7,8). Diagnosis of urethral stones can be made on a plain X-Ray of pelvis as they are mostly radio opaque.…”

A prospective evaluation of high- and low-power holmium laser settings for transurethral lithotripsy in the management of adults with urethral stone

“…Numerous variables, such as gender, geographic location, climate, lifestyle, and genetic changes all affect the prevalence of urinary stones [32][33][34]. About 13% of men and 7% of women have symptoms of urinary stone disease at some point in their lives.…”
