[THREE CASES OF TRANSURETHRAL RESECTION OF THE BLADDER TUMOR (TURBT), PERFORMED FOR BLADDER TUMOR ON THE ANTERIOR...

Three cases are reported of TURBT on the anterior wall, with bladder rupture occurring after discharge. Patient 1 was a 68-year-old man. He had macroscopic hematuria and he strained to void a bloody clot on the 10th day after TURBT. Subsequently, right lower abdominal pain occurred. Computed tomography (CT) revealed the extravasation of contrast medium into the prevesical space. He was diagnosed with extraperitoneal bladder rupture, and a urethral catheter was indwelled. Cancer invasion of muscle was diagnosed by pathological examination and total cystectomy was scheduled one and a half months later, but the prostate could not be resected due to hard tissue around the bladder neck. Patient 2 was an 82-year-old man and had a history of radiation therapy for a muscle invasive bladder tumor. He complained of pollakisuria two weeks after TURBT, and renal failure was detected on a blood test. CT revealed ascites, and a urethral catheter was indwelled. Ascites disappeared, but the urethral catheter deviated into the abdominal cavity based on repeated CT the next day, and he was diagnosed with intraperitoneal bladder rupture. Emergent surgery was performed, and the ruptured part was sutured with omentum covering and a cystostomy was created. Patient 3 was an 83-year-old man undergoing treatment for benign prostatic hypertrophy (BPH). He had received bladder instillation therapy of Bacillus Calmette-Guerin (BCG) ten months previously. When urinating 6 days after TURBT, lower abdominal pain developed. CT demonstrated retroperitoneal bladder rupture, and a urethral catheter was indwelled. The urethral catheter was removed 6 days later, but lower abdominal pain occurred again the next day. Thus, the urethral catheter was re-indwelled for a further two weeks.In TURBT on the anterior wall or dome, for the patients who had previously received radiation therapy to the pelvis, or intravesical instillation therapy of the BCG or accompanied by urinary disturbance, such as BPH, it is necessary to consider bladder rupture after discharge.
