We report a case in which retroperitoneoscopic pyelolithotomy was the procedure selected to treat a large stone in the upper urinary tract. A 71-year-old woman who had multiple cerebral infarction and dementia was admitted with a persistent high fever unresponsive to antibiotics. The diagnosis was pyelonephritis and urosepsis associated with ureteral calculus. A large calculus(3.0 x 2.0 cm)was found in the left ureter at the L3 level. She underwent nephrostomy of the left side. After the patient's general condition had improved, surgery was performed successfully with an uneventful recovery. The findings in this case confirm that retroperitoneoscopic surgery allows removal of a large stone in a single, minimally invasive procedures.

We report a rare case of intra-abdominal fibromatosis of the jejunal mesentery. A 71-year-old man, who was incidentally diagnosed with left hydronephrosis, was found to have a tumor near the duodeno-jejunal junction. The tumor appeared to invade the intestinal wall and was obstructing the left ureter. The tumor was indefinite in diagnosis preoperatively. The patient underwent an en-bloc excision of the tumor by a partial duodeno-jejunectomy combined with a left nephrectomy. Microscopic examination of the tumor showed that non-dysplastic fibroblasts proliferating in the jejunal mesentery had infiltrated into the adjacent small intestines and ureter, resulting in a diagnosis of intra-abdominal fibromatosis. This diagnosis was supported by findings of immunohistochemical analyses showing positive staining for vimentin and smooth muscle actin and negativity for keratin, CD34, C-kit and S-100. To our knowledge, this is the first documented case of intra-abdominal fibromatosis of the jejunal mesentery completely resected with the operative procedure described herein. In cases of a preoperatively undiagnosed retroperitoneal or mesenteric tumor that invades adjacent structures, it is important to consider intra-abdominal fibromatosis as a possible differential diagnosis. This may be helpful in planning the appropriate therapeutic strategies including extended multi-organ resection in selected patients.

A 71-year old male visited our hospital with a chief complaint of pollakisuria. The needle biopsies of the prostate were performed with PSA 8.0 ng/ml, and he was diagnosed as moderately differentiated adenocarcinoma. Imaging techniques revealed a right complete duplicated upper urinary system with an ectopic ureter draining to the prostatic urethra. He received radical prostatectomy with concomitant anastomosis of ureter to ureter. There is no evidence of hydronephrosis or tumor recurrence 11 months after operation. This is, to our knowledge, the second case report describing the association of radical prostatectomy and ectopic ureter.

A 71-yr-old male kidney transplant recipient suffered from delayed graft function. Eighty days after transplantation complete obstruction of the proximal ureter was observed, complicated by recurrent urinary tract infections. Two months later, the donor kidney was removed because of infectious complications and inadequate arterial perfusion. Histological examination of the removed graft showed signs of rejection as well as a low-grade papillary urothelial cell carcinoma of donor origin in the ureter. The remaining donor ureter was removed subsequently and showed no further signs of malignancy. Follow-up of the patient until 12 months after surgery did not reveal recurrence of the tumor. This case report is the first to describe accidental transfer of urothelial cell carcinoma in the ureter by transplantation, highlighting the possibility of malignancy when early stenosis is not related to the anastomosis. It again emphasizes the need for precise and cautious screening of organ donors, especially those of higher age.

A 71-year-old woman presented with lower abdominal pain and urinary incontinence 18 days after low anterior resection for rectal cancer. Computed tomography and magnetic resonance urography revealed right hydronephrosis, cystic mass in the right pelvic cavity and hydrometra. Positron emission tomography showed dilated right upper urinary tract communicating with dilated right fallopian tube and uterine body, and the finding was quite characteristic. Laboratory studies revealed that the serum and the fluid from hydrometra levels of creatinine were 1.06 mg/dL and 6.15 mg/dL, respectively. We diagnosed this case as uretero-fallopian fistula. Since the conservative management of uretero-fallopian fistula with ureteral stent was not accomplished, she underwent right ureteroureterostomy and adnexectomy. The intraoperative findings included dilated right ureter and fallopian tube adherent to the stenotic right ureteral segment ligated by suture during prior surgery. The histopathological findings showed endometriosis and inflammatory changes of uterine appendages. Follow-up at 3 months demonstrated resolution of the urinary incontinence and the ureteral obstruction and fistula.

We report an extremely rare case of squamous cell carcinoma (SCC) of the renal pelvis associated with an incompletely duplicated renal pelvis and ureter. A 71-year-old woman presented with left lower back pain and gross hematuria. Urinary cytology showed atypical squamous cells. Computed tomography, magnetic resonance imaging and retrograde pyelography revealed left incompletely duplicated renal pelvis and ureter and a mass in the left upper renal pelvis. A clinical diagnosis of left renal pelvic cancer was made and the patient underwent total nephroureterectomy. Histological examination of the resected specimen revealed SCC with marked keratinization in the upper renal pelvis. The tumor had invaded the renal parenchyma and perinephric fat. There was no urothelial carcinoma component. The pathological stage was pT4 N0. There was no evidence of recurrence 6 months postoperatively. Because the prognosis of SCC of the upper urinary tract is poor, urologists and pathologists should be aware that SCC may develop in duplicated urinary systems.

A 71 -year-old man was referred to our hospital because of repeated bowel obstruction. He had previously undergone cystectomy with ileal conduit urinary diversion for the treatment of bladder cancer at the age of 28 years. Computed tomography revealed a mass in the ascending colon. Ileostomy was initially performed because of poor general condition that improved with postoperative nutrition management. Enema findings revealed ascending colon cancer and we therefore decided to perform curative surgery. Intraoperative findings revealed that the ascending colon cancer had invaded the ileal conduit. However, it was confirmed that the ureter-ileal conduit anastomosis and the mesentery of the ileal conduit could be preserved. We performed right colectomy and partial resection of the ileal conduit with curative intent. The pathological stage was pT4bpN0cM0, pStage II. There were no signs of recurrence 15 months after curative surgery.

We report a rare case of iliac vein compression syndrome caused by urethral calculus. A 71-year-old man had a history of urethral stenosis. He complained of bilateral leg edema and dysuria for 1 week. Physical examination revealed bilateral distention of the superficial epigastric veins, so obstruction of both common iliac veins or the inferior vena cava was suspected. Plain abdominal computed tomography showed a calculus in the pendulous urethra, distention of the bladder (as well as the right renal pelvis and ureter), and compression of the bilateral common iliac veins by the distended bladder. Iliac vein compression syndrome was diagnosed. Bilateral iliac vein compression due to bladder distention (secondary to neurogenic bladder, benign prostatic hyperplasia, or urethral calculus as in this case) is an infrequent cause of acute bilateral leg edema. Detecting distention of the superficial epigastric veins provides a clue for diagnosis of this syndrome.

A 71-year-old woman was referred to our department for a nodular lesion in the left lung. She had been followed by urology department in our hospital for 6 years since right nephrectomy for ureter cancer. Chest X-ray and computed tomography (CT) scan demonstrated a small nodular shadow in the left lower lobe. The lung tumor was removed by wedge resection, and pathologically diagnosed during the operation as a metastasis from the ureter cancer. The lung tumor consisted of clear cells similar to the ureter cancer. However, the final pathological diagnosis changed to a primary lung cancer based on the findings of stratified differentiation and cancer cell nests in the tumor. Immunohistochemical staining for ureter epithelium-related antigens confirmed the diagnosis. Although we recommended left lower completion lobectomy, the patient refused additional surgery. She is suspected to have local recurrence in the left lower lobe 18 months after the surgery.
