[A case of scrotal bladder hernia containing bladder cancer].

A 70-year-old man had a history of total laryngectomy for laryngeal cancer and bilateral inguinal hernia repair 5 years previously. The patient had suffered from difficulty with urination since then and had been treated for prostatic hypertrophy at our department. He developed microscopic hematuria from June 1991, and was admitted because a bladder tumor was detected by cystoscopy. Cystography showed a scrotal bladder hernia with filling defects in the bladder per se and the bladder hernia as well. Cystoscopy revealed tumors in the hernia and in the vicinity of the ureteral orifice. Biopsy indicated transitional cell carcinoma. Voiding cystourethrography showed normal urination and no residual urine. Excision of the tumor-containing hernia, partial cystectomy with right ureteral orifice, and reconstruction of the right inguinal canal were performed on October 25, 1991. The postoperative course was favorable and he was discharged on the 40th postoperative day. The tumors were respectively stage as TCC, G1, and pT1a, and TCC, G1 greater than G2, and pT1b. Thirty five cases of bladder hernia that have been reported in Japan. Eight cases of accompanied by cancer have been reported in Japanese (3 cases) and foreign (5 cases) literatures. These are reviewed and discussed.

[Milk of calcium renal stone treated with endoscopic extraction: a case report].

The patient, an 18-year-old woman, visited a local doctor complaining of right flank pain. Characteristic findings obtained by X-ray examination suggested milk of calcium renal stone in the calyceal diverticulum of the right kidney, she was introduced to our clinic on February 16, 1989. Although examinations on admission showed no urinary tract obstruction or renal function disorders, since she repeatedly suffered from flank pain, we decided to remove the stone percutaneously and widen the mouth of the diverticulum. Conventional percutaneous nephrolithotripsy methods were used to endoscopically remove the stone but we were unable to ascertain the mouth of the calyceal diverticulum. Thus, we removed the nephrostomy tube. The stone was composed to 83% calcium oxalate and 17% calcium phosphate. She was released from the hospital with no particular postoperative complications and at present the flank pain has disappeared. Percutaneous treatments against milk of calcium renal stone are discussed.

[Rhabdomyosarcoma of the prostate: report of a case and review of the literature].

Rhabdomyosarcoma of the prostate is a rare tumor and its prognosis is extremely poor. However, the survival rate has been gradually improved by using combined chemotherapy. A 17-year-old man with the chief complaint of dysuria was referred to our hospital on April 7, 1986. Prostatic needle biopsy was performed and pathological diagnosis was rhabdomyosarcoma of the prostate. The patient was given preoperative combined chemotherapy consisting of actinomycin D and cyclophosphamide. Total cystoprostaurethrectomy and ileal conduit were performed on April 30, 1986. He underwent postoperative combined chemotherapy (vincristine, actinomycin D, cyclophosphamide). He is well 13 months after his initial symptoms and is clinically free of tumor 12 months postoperatively. Forty-two cases of rhabdomyosarcoma of the prostate including our case were collected from the Japanese literature and reviewed with respect to the multimodal treatment and prognosis.

[A case of giant hydronephrosis with renal pelvic calcification].

A 26-year-old man had asymptomatic macroscopic hematuria. A left hydronephrotic sac outlined with a thin curvilinear shadow of calcium deposition was found in a plain film and stenosis at the ureteropelvic junction (UPJ) in a retrograde pyelogram. Left nephrectomy was performed and the fluid content was 1330 ml. Histologic examination showed subepithelial calcification of the renal pelvis and fibrous proliferation at the UPJ.

[A case of an incompletely duplicated ventral urethra].

A ventral incomplete duplicated urethra was found in a 20-year-old male. The accessory urethra lay ventral to and in parallel with the normal urethra. The external orifice of the accessory urethra was also ventral to the orifice of the normal urethra in the glans. On the other hand, the accessory urethra was closed near the bulbar region, and an abscess was found at the dead end. The accessory urethra, which was 9 cm long, was surgically removed. Histopathologically, the luminal surface was covered with a stratified squamous epithelium; and, smooth muscle and spongy tissue were observed around the accessory urethra. The classification of the duplicated urethra is discussed.
