膀胱癌に対する膀胱全摘除術から16年後に回腸新膀胱による尿路再建を行った1例

Abstract

We report a 59-year old male patient who successfully underwent urinary reconstruction by ileal neobladder that was performed 16 years after total cystectomy and ureterocutaneostomy for bladder cancer. He had been suffering from refractory contact dermatitis around the ureterocutaneostomy stoma and was referred to our hospital. In 2003, bilateral percutaneous nephrostomy was performed together with ureteral ligation at the most distal part. However recurrent pyelonephritis developed afterward because of nephrostomy catheter troubles and the patient's quality of life was markedly impaired. Then urinary reconstruction was planned in 2005. Because the urethra had not been resected and remained intact, ileal neobladder (Hautmann's method) was successfully created and he was free from nephrostomy catheter. Postoperatively there has been no recurrence of pyelonephritis. Long time insertion of nephrostomy catheter causes several complications, such as urinary tract infection and formation of urinary stones. To preserve renal function and improve quality of life, every chance for urinary reconstruction should be sought in those patients who suffer from upper urinary tract catheter troubles.
