A 62-year-old man was admitted to our hospital with the chief complaint of right flank pain. Abdominal computed tomographic scan revealed a right hydronephrosis and intrapelvic tumor. Ultrasound revealed a renal mass lesion. Ultrasound guided renal biopsy and laparotomy of intrapelvic tumor was performed. The histopathological diagnosis was renal cell carcinoma and ureteral transitional cell carcinoma.

An 83-year-old woman presented with left flank pain and high grade fever. After left ureteral catheterization and intensive chemotherapy with hemoperfusion, surgical exploration revealed the lower pole branches of the renal vessels were obstructing the ureteropelvic junction (UPJ), and dissection of the vessels released the obstruction. An 82-year-old man presented with right flank pain. Angiography demonstrated UPJ obstruction caused by the lower pole branch of the renal artery. Arterial dissection with dismembered pyeloplasty resulted in improvement of obstruction. In both cases, the patients had a long history of hypertension with mild to severe arteriosclerosis. Arteriosclerosis associated with fixation of the UPJ, may be one of the important factors leading to progressive hydronephrosis in geriatric patients.

We report a case of appendiceal abscess complicated with right hydronephrosis in a 67-year-old woman. She visited our department complaining of right flank pain. Intravenous pyelography (IVP) showed hydronephrosis and hydroureter on right and a narrow ureter at the pelvic brim. A pelvic computed tomographic scan revealed a low density area measuring 44 x 37 mm in size, anterior to the right ureter, which was thought to be a pelvic tumor. Further examination did not reveal the origin of the tumor. An exploratory laparotomy was performed. The tumor developed from the cecum and adhered to the right ureter. The appendix was not found. The tumor was resected with the cecum while the ureter was preserved. Histological investigations revealed an appendiceal abscess. The postoperative course was uneventful. IVP after the operation showed the hydronephrosis to have resolved.

A 48-year-old female was found to have right flank pain at another hospital and transabdominal ultrasonography showed right hydronephrosis. She was referred to our department for further examination. She had undergone right oophorectomy and total hysterectomy 3 years before. Intravenous pyelography showed right hydronephrosis and retrograde pyelography revealed ureteral stenosis at the lower portion of the right ureter. Endometriosis had developed at the site of previous surgery on the appendix. A mass was formed in an extensive area including the endometriotic lesion, due to adhesion following previous surgery or other reasons, and extended to the retroperitoneum, thereby inducing right ureteral stenosis. The postoperative course was uneventful. The pathological diagnosis was endometriosis of the residual appendix.

A 35-year-old woman was hospitalized at 39 weeks 0 days of gestation because of acute left flank pain. Magnetic resonance imaging (MRI) revealed bilateral hydronephrosis with peripelvic extravasation of contrast material around the left kidney. The pregnancy ended with a cesarean section and after the cesarean section a left double-J-stent was placed cystoscopically. An excretory urogram following the removal of the ureteral stent showed no extravasation or hydronephrosis in either kidney.

Although ureteral obstruction is rarely noted in patients with gastric cancer at an advanced stage or at autopsy, the condition caused by authentic ureteral metastasis of gastric cancer is extremely rare. We experienced a case of gastric cancer in a 51-year-old woman who showed bilateral ureteral metastasis. The patient initially complained of right flank pain, caused by right ureteral obstruction, and was referred to our hospital, where she underwent a right nephroureterectomy, with suspicion of primary ureteral neoplasm. Histopathological examination of the resected specimen showed that metastatic growth of adenocarcinoma in the ureteral wall had caused the obstruction, and the subsequent extensive search for the primary lesion revealed asymptomatic gastric cancer. Soon after the nephroureterectomy, the patient developed left hydronephrosis, possibly caused by left ureteral metastasis, and a left percutaneous nephrostomy was performed. She then received chemotherapeutic reagents. However, she finally developed peritoneal carcinomatosis, and died of the disease about 1 year after the onset of the disease. In this report, we also review true ureteral metastasis from the stomach, and discuss the clinicopathologic features.

Over a 5-year period, 1007 patients with haematuria were investigated, using a protocol based on ultrasonography as the upper tract imaging modality of choice. Intravenous urography (IVU) was only used in selected individuals, including those patients with bladder cancer suspected on cystoscopy, suspicious or malignant cytology, previous investigation for haematuria, on-going haematuria at the time of their clinic visit, a history of flank pain or hydronephrosis on ultrasonography. Of this series, 840 (83%) had visible haematuria, 158 (15%) had microscopic or chemical haematuria and 9 (0.9%) had unspecified haematuria. A total of 133 bladder transitional cell tumours, 21 renal cell cancers and 2 upper tract transitional cell cancers (TCC) were diagnosed. The sensitivity of ultrasound with respect to bladder cancer was 63% and the specificity 99%. The odds ratio of diagnosing cancer in patients with visible haematuria compared to microscopic or unspecified haematuria was 3.3. No upper tract tumours were missed using this investigational protocol. An ultrasonography-based protocol could miss fewer upper tract TCCs than a standard IVU-based service would miss renal cell cancer. Provided there is no history of flank pain, no malignant cytology, no hydronephrosis and no previously investigated haematuria, IVU could be safely omitted.

A 36-year-old man was admitted to hospital due to right flank pain as a result of ureteral stones. He had been followed up for type 1 glycogen storage disease since the age of 11 years. He had four episodes of spontaneous stone birth during the previous 2 years, and each stone was composed mainly of calcium oxalate. Intravenous pyelography showed right hydronephrosis due to ureteral stones and bilateral multiple renal stones. We carried out transurethral ureterolithotripsy (TUL) on the right ureteral stones. The composition was a mixture of calcium oxalate and calcium phosphate. Laboratory evaluation demonstrated the association of distal renal tubular acidosis (RTA). These observations suggest that hypocitraturia and distal RTA are strongly correlated to recurrence of calcium nephrolithiasis. The patient's serum uric acid and urinary citrate excretion levels normalized after allopurinol and potassium citrate administration.

The choice of the most suitable technique for radiologic evaluation of upper urinary tract stones depends on the precise clinical questions that have to be answered. Many of these questions can still be answered by plain films of the abdomen and excretory urography. This review addresses the value of ultrasonography and computed tomography (CT) with respect to the two most important clinical questions, i.e. 1) presence/extent of obstruction/hydronephrosis and perinephric abscess in patients with acute flank pain; and 2) precise location, number and size of calculi. Because its sensitivity is comparable with CT and it is widely available, ultrasonography in the hands of experienced clinicians/radiologists may be preferred for evaluation of patients with acute flank pain. However, it must be emphasized that ultrasonography may totally miss acute ureteral obstruction/hydronephrosis within the first 12-24 hours. In children as well as in pregnant women, ultrasonography is still the technique of choice, but it may be replaced by magnetic resonance urography in the future. For precise stone location or detection of calcifications, however, the speed, safety and accuracy of unenhanced helical CT make this the most sensitive method and therefore the technique of choice. It also detects urinary calculi more accurately and exposes patients to less radiation than the traditional combined plain abdominal film/intravenous urography. Furthermore, CT can most readily reveal alternative diagnoses in patients with acute flank pain and other intraabdominal pathologies than stones.

We report a case of carcinoembryonic antigen (CEA)-producing renal pelvic and ureteral cancer. A 62-year-old man consulted a local hospital with the chief complaint of right flank pain. On ultrasonography and CT scan, right hydronephrosis with the renal pelvis and ureteral tumor were detected, and he was referred to our hospital. Both serum levels of CEA and CA19-9 were elevated to 36.9 ng/ml and 119 u/ml, respectively. Close examination of the gastro-intestinal tract did not detect any sign of digestive tumor. Right nephro-ureterectomy was performed, and the tumor was histologically diagnosed as TCC G2 > G3 pT3, and CEA was positive in the tumor cells immunohistochemically. CA19-9 was also positive both in the tumor cells and normal epithelium of the renal tubules. Postoperatively, multiple lung metastases developed despite chemotherapy and the patient died 4 months after surgery. CA19-9 had immediately decreased to the normal range after preoperative percutaneous nephrostomy. CEA had transiently decreased postoperatively, but then increased with lung metastases, apparently related to the state of cancer.
