Robotic partial cystectomy with excision of mesh after inguinal hernia repair: a case report

Mesh erosion into the bladder after hernioplasty is sparsely reported in literature and may be underestimated in clinical practice. We report a case of a patient who was referred to our department due to recurrent urinary tract infections caused by a bladder stone due to mesh migration after inguinal hernia repair 22 years ago.

A 67-year-old male patient was referred from the outpatient urologist for transurethral resection of the prostate in September 2021 due to recurrent urinary tract infections caused by benign prostatic enlargement and bladder stone formation. During the operation, parts of the stone were smashed and the prostate was resected. Additionally, a mesh eroding from the bladder roof was detected masqueraded by the stone. A computed tomography scan, which was performed afterwards, revealed a 20 × 25 mm mesh migration into the bladder after inguinal hernia repair on the left with concomitant stone adhesion to the mesh. After revealing patient history, an inguinal hernia repair with mesh implantation was done 22 years ago. A robotic assisted partial cystectomy and mesh excision was performed. The patient recovered well.

Mesh erosion into the urinary bladder after hernia repair can occur up to two decades after the primary operation. Although it is rarely reported, it can be a possible cause for recurrent urinary tract infections and therefore a mentionable complication after inguinal hernia operation. Robotic-assisted laparoscopic partial cystectomy with complete excision of the mesh is an option for definitive treatment.
