Abstract
Abstract Objective The scrotal urethrocutaneous fistula is an uncommon pathology which can lead to serious complications, such as infections, scrotal abscesses, or even Fournier’s gangrene. We present an unusual case of scrotal urethrocutaneous fistula secondary to erosion of a penile prosthesis tubing in a patient with a history of erectile dysfunction. Case presentation A 68-year-old patient with no previous comorbidities and a history of prostate adenocarcinoma that was treated with radical prostatectomy + lymphadenectomy, without the need for subsequent adjuvant therapy. He was diagnosed with erectile dysfunction after surgery, refractory to intracavernous therapy therefore required a 3-component penile implant placement procedure performed extra-institutionally. Two years after the surgery, he consulted with our institution for scrotal pain and urine leak from the scrotum during micturition. Physical examination shows extrusion of prosthesis tubes in the scrotal area with no signs of infection or exposure of the cylinders. The patient was hospitalized for management with antibiotics and to replace the penile implant. A retrograde urethrography with contrast medium was performed during surgery. Fluoroscopy showed a fistulous pathway between the penile urethra and the scrotum. No passage of the contrast to the corpora cavernosa was seen. The urethral lesion and fistula were identified and repaired. A malleable prosthesis was used, considering the amount of scar tissue. The patient had an adequate postoperative period. A urethral catheter and a cystotomy were used for six weeks. After catheter removal, a voiding cystogram was performed, finding no fistulas. The patient was followed for 11 months with no complications. Conclusion Although scrotal urethrocutaneous fistulas are an infrequent complication after penile prosthesis implantation, a timely diagnosis is essential for conservative treatment and to avoid life-threatening complications. Financing No conflict.
