Ureteric trauma constitutes a serious disease which can induce renal complications. Ureteric trauma is often iatrogenic, mainly due to gynaecological surgery. The authors report a series of 42 cases of ureteric trauma observed over a 20-year period. These patients consisted of 33 females (78%) and 9 males (21%) with a mean age of 38 years (range: 20 to 65 years). 24 ureteric lesions (57%) were secondary to obstetric procedures and operations, 9(21%) were due to gynaecological operations (hysterectomy), ureteroscopy was responsible in 3 cases, 2 lesions were due to lumbar sympathectomy, one case was secondary to resection of the rectum and 2 cases were secondary to abdominal trauma. The most frequent lesion was ureteric section (21 cases), usually affecting the pelvic ureter. Iatrogenic lesions were associated with iliac vessel ligation (1 case) and vesicovaginal fistulas (8 cases). The clinical features were dominated by vaginal urinary fistula (33 cases) and low back pain (15 cases). The diagnosis was essentially based on IVU, which showed ureterohydronephrosis in 18 cases and a silent kidney in 2 cases. Eight ureteric lesions were diagnosed at operation, 31 after an interval of 3 to 20 days and 2 after an interval of 3 months. Treatment consisted of ureterovesical reimplantation in 17 cases, Boari-Kuss bladder flap in 3 cases, psoas bladder in 6 cases, end-to-end ureterorraphy in 5 cases, ileoureteroplasty in 3 cases, nephrectomy in 2 cases, appendicoplasty in 1 case, double J stent in 2 cases. The course was marked by the development of hydronephrosis (4 cases), ureteric stenosis (2 cases), vesico-ureteric reflux (1 case), urinary fistula (2 case) and lengthening of the ileal graft (1 case).

The authors report a case of nephrogenic metaplasia of the ureter in a 35-year-old patient presenting with left low back pain, haematuria and frequency. Physical examination was not contributive. IVU showed a filling defect in the left iliac ureter. Ureteroscopy demonstrated a tumour nodule in the left iliac ureter. Ureteroscopic biopsy with histological examination showed nephrogenic metaplasia of the ureteric mucosa. Treatment consisted of ureterotomy with resection of the ureteric polyp, followed by closure of the ureterotomy over a double J stent. The course was favourable and postoperative follow-up (IVU, cystoscopy) at 6 months and 12 months was normal.

A 25-year-old man was admitted to our hospital because of left lumbago. An abdominal X-ray film demonstrated multiple calculi in the medullary positions of both kidneys and an impacted calculus in the left ureter. He was diagnosed with bilateral nephrocalcinosis and nerve deafness due to distal renal tubular acidosis (RTA) in childhood and was treated with alkali agents for several years. Extracorporeal shock wave lithotripsy was performed successfully against the left ureteral calculus. His older brother had also been diagnosed with RTA and nephrocalcinosis at the age of 2 years and 6 months. Nephrocalcinosis due to RTA associated with nerve deafness in brothers is rarely reported.

We report a 74-year-old male who developed ureteral carcinoma after 11 years of radical cystectomy and rectal bladder reconstruction. The patient had right lumbago and high grade fever and right hydronephrosis. He was suspected to have right ureter tumor under the antegrade pyelography at the time of right nephrostomy, and ureter tumor was diagnosed by the combination of computed tomography and antegrade pyelography. Under this preoperative diagnosis, right nephroureterectomy was performed. The histopathological diagnosis was transitional cell carcinoma. Since the recurrence of urothelial cancer at 10 years after radical cystectomy is rare, we believe our case is useful for the establishment of long-term follow up of bladder cancer.

Adenocarcinoma of the pancreas has a low 5-year survival rate of approximately 5%. Early diagnostics of pancreatic carcinoma during early tumor stages is made difficult by the lack of symptoms. In particular, individuals suffering from carcinomas located within the pancreatic tail are at high risk of a missed diagnosis. The early symptoms are usually nonspecific (e.g., nonspecific upper abdominal complaints, decrease in weight, loss of appetite, and impaired performance) and are characteristic only in carcinomas of the pancreatic head with painless icterus. If the patient complains of low back pain, a severe infiltration with no chance of a complete surgical resection is found in most cases. An adenocarcinoma of the pancreatic tail was diagnosed in this case report based on a large retroperitoneal extravasation missing further symptoms. The extravasation found represented a primary infiltration of the left ureter which was not diagnosed in primary computed tomography.

A 44-year-old Japanese woman presented with a left low back pain. Abdominal ultrasonography revealed the left hydroureteronephrosis. She had the past history of endometriosis interna 3 years before. Retrograde pyelography showed the defect in the ureter, and on ureteroscopy, a polypoid mass was identified. Biopsy specimen from the ureteral mass showed endometrioid epithelia and edematous endometrial stroma, immunohistochemically positive for progesterone receptor (PgR), estrogen receptor (ER), and CD 10. For the lesion (endometrioma), partial resection of the ureter and ureteroneocystostomy with Boari flap were performed. The resected specimen showed a 2-cm polypoid mass. Histologically, the lesion was ureteral endometriosis. The postoperative course was uneventful, the patient showed no evidence of local recurrence after the initial resection and continues to be under close follow up. Urinary tract involvement of endometriosis is uncommon. Endometriosis should be included in the differential diagnosis of ureteral strictures in sexually active young females.

The author presents a unique case of a synchronous triple carcinoma of kidney, ureter, and urinary bladder. A 73-year-old man was admitted to our hospital because of hematuria and lumbago. Endoscopy and imaging modalities revealed a bladder tumor, a left ureter tumor, and a left kidney tumor. No other tumors were found in the body by imaging modalities. Cystectomy and left nephroureterectomy were performed. The bladder tumor was a large polypoid tumor consisting of pleomorphic sarcomatoid carcinoma (80%) and high-grade papillary urothelial carcinoma (20%), both invading the deep muscle layer. There were gradual merges between the two. The sarcomatous component was composed of malignant spindle, polygonal, and giant cells. Lymphovascular permeation was pronounced. Immunohistochemically, the sarcomatous element was positive for vimentin and various types of cytokeratins (CK), while the urothelial carcinoma element was positive for various types of CK and negative for vimentin. The ureter tumor was small and obstructed the ureter lumen. It was a pure squamous cell carcinoma without a urothelial component. The ureter tumor invaded the adventitia. A mild degree of lymphovascular invasion was recognized. Immunohistochemically, the tumor cells were positive for various types of CK but negative for vimentin. In the kidney, almost the entire kidney parenchyma was replaced by a tumor. The renal pelvis was broadly erosive but was free of apparent tumors. Histologically, the renal tumor was a pure squamous cell carcinoma without a urothelial component. Broad necrosis was present, and lymphovascular permeation was pronounced. The renal pelvis and calices were devoid of apparent tumor cells, but renal squamous cell carcinoma was present just beneath the pelvis and calices. Immunohistochemically, the kidney tumor was positive for various types of CK and negative for vimentin.

Ureteric stones are a common cause of obstruction of the urinary tract, usually presenting with characteristic signs and symptoms, such as acute ureteric colic and hematuria. Occasionally, stones may present with non-specific symptoms such as low back pain and remain unidentified, leading to stone growth, chronic ureteric obstruction and complications such as hydronephrosis and renal damage. Here, we report a large ureteric stone in a cadaver with complete obstruction at the left ureterovesical junction, resulting in severe dilatation of the left ureter and renal pelvis.

Undifferentiated carcinoma of ureter is rare neoplastic lesion, and the natural history of undifferentiated carcinoma of ureter has not been known well yet. We hereby presented an autopsy case of undifferentiated carcinoma of the ureter with rapid progression from the initial stage. A 62-year-old male visited the local urologist complaining of asymptomatic gross hematuria. Cystoscopy revealed the outflow of hematuria from the right ureteral orifice. Abdominal CT showed the right hydronephrosis with atrophic change of the renal parenchyma and the stenosis of upper ureter. He was referred to our hospital on suspicion of a right ureteral tumor. Magnetic resonance imaging and retrograde ureterography did not reveal a tumor in the right ureter. He complained of low back pain 4 months after the initial hematuria, and CT revealed the diffuse enlargement of the right kidney, swelling of the abdominal lymph nodes, and lung nodules. Renal biopsy was done, and only undifferentiated cells were revealed histopathologically without any specific findings to diagnose the primary organ. The tumor increased progressively, and he died about 6 months after the initial gross hematuria. Autopsy was performed, and urothelial carcinoma was found in the right ureter as the primary lesion. The ureteral tumor infiltrated to the right kidney, right adrenal gland, liver, duodenum, and pancreas with undifferentiation. Undifferentiated tumor cells were also found in distant metastatic lesion including the abdominal lymph nodes, left adrenal gland, liver, lung, pleura, and peritoneum.

We report a case of a 64-year-old male with right pyonephrosis due to ureteral stones in association with chronic renal failure. The patient had been treated with hemodialysis for fourteen years. He was admitted to the Department of Internal Medicine of Kurobe City Hospital with chief complaints of fever and lumbago in January 2013. CT demonstrated a right pyonephrosis accompanied by right ureteral stones positioned in the middle and lower ureter. The stones could not be detected by KUB. He was consequently referred to the Department of Urology. Firstly, percutaneous nephrostomy for the right kidney was performed, and 200 ml of pyuria was discharged at that time. Urine culture demonstrated Escherichia coli. Secondly, rigid transurethral ureterolithotripsy (TUL) for the right ureteral stones was performed using Lithoclast, and a ureteral stent was indwelled on day 15 after nephrostomy construction. The nephrostomy catheter and ureteral stent were removed 10 and 21 days after the operation, respectively. The constituents of the stone were CaOx (26%) and CaP (74%). Right hydronephrosis improved and the patient showed no pyelonephritis for 1 year postoperatively.
