A 64-year-old man was hospitalized for massive bleeding from the cutaneous ureterostomy. He had undergone pelvic exenteration with the ureterostomy for rectal cancer invading the bladder five months previously and retrograde ureteric catheters were inserted bilaterally into the ureters. An aortography revealed a pseudoaneurysm of the abdominal aorta in the region transversed by the left ureter. He was successfully treated by en bloc resection of the aortoureteric fistula and the left ureter and repair of the aorta by Dacron patchplasty. Left nephrectomy was also performed because of pyelonephritis. He has had no signs of cancer recurrence or graft infection five years after this operation.

Study on detection of malignant cells in urinary sediments using supravital staining was described. We examined 96,554 specimens of urinary sediments for 2 years from January 1985 to December 1986. The results of microscopic urinalysis were compared with the cytological and histological diagnoses. Atypical cells were found in 138 patients, and 47 (34.1%) cancers were diagnosed histologically among them. These included 33 bladder cancer, 1 ureter cancer, 1 renal pelvic cancer, 2 prostate cancers, 1 rectal cancer, and 9 uterine cancers. Seven patients of them had not been under suspicion of malignancy yet before atypical cells were detected. Therefore microscopic urinalysis caused the triggers of cancer diagnoses. For bladder cancers, the positive rates in microscopic urinalysis were 43.4%, and those in urinary cytology were 52.4%. The positivity revealed higher in high-grade cancers than in low-grade. As compared with the results between microscopic urinalysis and urinary cytology in identical patients, the rate of correspondence between them was 89.5%. In 61.2% of positive and suspicious urinary cytology, atypical cells were not found. Atypical cells were seen in negative urinary cytology of 26 cases, and 5 cases of cancers were diagnosed histologically. These suggested that microscopic urinalysis as a screening for malignant cells was useful to detect urinary tract malignancy combining with urinary cytology.

A case of delayed bilateral ischemic necrosis of the pelvic ureter in a 66-year-old woman submitted to abdominal perineal resection and hysterectomy for advanced rectal cancer, is reported. Five days after the operation urine was observed in the perineal cavity. External urine diversion was carried out by catheterizing the ureteral stumps through the perineal cavity. The reconstructive procedure was performed at a later date by bilateral ureteroileocystoplasty with a defunctionalized loop. The vascular anatomy of the ureter is discussed to highlight the essential technical details useful for prevention of ischemic injury.

We report a clinical case of carcinoma of the rectum. A 45-year-old patient had undergone resection of the rectum and proctostomy 22 months ago. Carcinoma caused metastasis to the corpora cavernosa of the penis in this patient, and caused local recurrence of the carcinoma of the rectum, pulmonary metastasis and malignant priapism. A statistical analysis of 62 cases of secondary tumor of the penis in Japan was also made. The present clinical case was the 62nd case of secondary tumor of the penis in Japan, and the 4th case of secondary penile tumor from the rectum. The primary foci of the secondary tumor of the penis are mostly in the urinary bladder and the prostate, followed by the rectum, kidney, pelvis of the kidney and the ureter. Primary sites in the urogenital organs were found in 82.3% and in the neighboring organs in 85.2%. As the route of metastasis of the secondary tumor of the penis, arterial blood, retrovenous, retro-lymph and direct infiltrating metastasis may be possible. Secondary tumor of the penis is mostly found in aged persons, and the major symptoms may be penile nodule and mass, malignant priapism, penile pain and tenderness, and difficulty in urination and retention of urine. Regardless of the length to metastasis and difference in the treatment of the metastatic focus, the secondary tumor of the penis is poor in prognosis, and survival period may be up to 7 months. From the findings of post-mortem examination, secondary tumor of the penis should be regarded as a secondary sign due to recurrence of the primary tumor or presence of metastasis in other organs, and careless surgical operation should be avoided.

We report a case of uretero-aortic fistula. A 69-year-old man with rectal cancer underwent a pelvic exenteration and a double--barreled cutaneous ureterostomy in the right lower abdomen. Stomal stenosis necessitated continuous indwelling of double J stents in the two ureters. Two years postoperatively, massive bleeding occurred during exchange of double J catheters. Occlusive ureterogram demonstrated a uretero-aortic fistula at the crosspoint between the left ureter and the aorta. The surgical repair consisted of closure of the aortic fistula, ligation of the left ureter proximal to the fistula and percutaneous left nephrostomy.

A 67-year-old man was referred for further examination of left hydronephrosis. He had undergone anterior resection for rectal cancer 2 years previously and also right lobectomy for a solitary hepatic metastasis one year postoperatively. Antegrade pyelography demonstrated a filling defect in middle portion of the left ureter. Cytology of the aspirated urine was class V. Left nephrourete-rectomy was performed. Histologically metastatic adenocarcinoma with intact ureteral mucosa was demonstrated.

Of the newer laparoscopic procedures for colorectal cancers the abdominoperineal resection of the rectum was previously communicated in this journal. The laparoscopic anterior resection is a more technically demanding operation. We report the case of 63 years old women with a rectal cancer at 9 cm from the anus. The procedure was realised under general anaesthesia, with a urinary catheter in place. An blunt obturator was introduced into the uterine cavity and used to manipulate the uterus during the procedure. After establishing of the pneumoperitoneum, a 30 degrees telescope was introduced through the umbilical port (10 mm). The 30 degrees telescope allows visualization of the splenic flexure and rectal side wall. The main steps of the procedure were the exploration of the abdominal cavity, mobilization of the descendent colon and sigmoid, exposure of the left ureter, division of the left sided peritoneal leaf and division of the inferior mesenteric vessels. The anterior dissection of the rectum was facilitated by manipulation of the uterus. The rectum was then mobilized with the "abdominalization of the tumor". A 5 cm left paramedian vertical incision was performed; through this incision a stapler was introduced and the rectum was transected 5 cm under the tumor. The rectum with the tumor, the sigmoid and mesosigmoid were exteriorized through the incision; the sigmoid was divided with a linear stapler cutter 20 cm above the tumor and the specimen was removed extracorporeally. The anvil of a circular stapler was secured in the left colon and returned in the abdominal cavity. The body of the stapler was inserted into the rectal stump through the anus and connected intracorporeally to the anvil. The postoperative evolution was simple; flatus and feces were passed at 48 hours. The patient was discharged to home after 6 days, 13 months after operation she has no morbidity.

We report herein the case of a 59-year-old woman who developed a local recurrence of rectal cancer which showed extremely rapid growth. The patient had undergone a curative low anterior resection with total mesoexcision, and was discharged on postoperative day 25 after an uneventful recovery. However, 2 months after the operation, she developed bleeding from the rectum during defecation, the quantity of which gradually increased. A colonoscopy performed during the fifth postoperative month revealed a circular tumor at the suture line. The tumor was unresectable because it had firmly invaded not only the sacrum, but also the right ureter. Despite the administration of 5-fluorouracil and leucovorin, the patient died of cancer 18 months after her initial surgery. Considering that local recurrence of rectal cancer does not usually occur within 1 year after surgery, this case is unusual because the local recurrence developed very early and showed extremely rapid growth, occupying the entire lumen of the rectum by the time it was detected by colonoscopy during the fifth postoperative month.

A 65-year-old man underwent transperineal drainage of pelvic abscess after rectal amputation for rectal cancer. The bladder wall and right ureter were injured during this operation, which led to vesicoperineal fistula and contracted bladder. We performed partial resection of the bladder (fistulectomy), augmentation ileocystoplasty (Cup-patch technique), and bilateral ureteral reimplantation (LeDuc-Camey technique). After surgery, the patient was able to void without any residual urine or incontinence. There was no hydronephrosis or resicoureteral reflux postoperatively. Augmentation cystoplasty is usually performed to treat a contracted bladder, but it can also be applied for the reconstruction of complicated lower urinary tract injury, and may improve the quality of life (QOL) dramatically.

A 70-year-old man who had undergone a low anterior resection for primary rectal cancer 9 years before complained of anorexia, hemiplegia, and recurrent laryngeal nerve palsy. The anorexia was caused by duodenal stenosis due to swollen lymph nodes, the hemiplegia was caused by a metastatic brain tumor, and the recurrent laryngeal nerve palsy was caused by metastases of the cancer to the mediastinal space. Metastases were also found in the bilateral lungs, liver, ureter, and cervical vertebra. In choosing the anesthesia for the gastrojejunostomy to improve the malnutrition of this patient, we decided, on the basis of the patient's full stomach, malnutrition, hypovolemia, hemiplegia, cerebral compression, recurrent laryngeal nerve palsy, renal dysfunction, and respiratory dysfunction, to use thoracic epidural anesthesia rather than spinal anesthesia or general anesthesia. Thoracic epidural anesthesia could provide sufficient analgesia, and the operation was uneventful. In anesthetic management of an end-stage patient undergoing a palliative operation like this, we should consider the purpose of the operation, its complications, and further complications which may be induced by anesthesia in order to plan out an anesthetic regimen unlikely to lead to harmful events in perioperative period.
