We report a case of primary fibroepithelial polyp of the right midureter. The patient was a 41-year-old-woman, complaining of right flank pain. An excretory urogram revealed right hydronephrosis and a filling defect of the the right midureter. The filling defect was produced by a large fibroepithelial polyp that was diagnosed and removed by ureteroscopy without open surgery. Large fibroepithelial ureteral polyps are relatively rare and ureteroscopy is the gold standard of diagnosis for ureteral filling defect.

A 63-year-old man was admitted with right flank pain, nausea and chill. CT scan revealed right hydronephrosis and rupture of ureter, but tumor or stone was not detected in the CT scan. However retrogradepylelography revealed right lower ureteral tumor, and this patient was treated by right nephroureterectomy and partial cystectomy. Histopathological examination of ureteral tumor showed transitional cell carcinoma. Spontaneous rupture of ureter due to ureteral cancer is a rare case, which has not been reported in the Japanese literature. Clinical study was performed about cases of spontaneous rupture of ureter which have been previously reported.

An 81-year-old woman was admitted to our hospital with left flank pain. Excretory urography revealed left hydronephrosis. Abdominal computed tomography (CT) revealed a large heterogenous tumor in the upper pole and marked hydronephrosis and hydroureter in the lower portion of the left kidney. Left total nephroureterectomy was performed under the diagnosis of renal pelvic and ureter tumor. The pathological diagnosis was of renal cell carcinoma (spindle type, grade 3) in the kidney and transitional cell carcinoma (grade 2) in the ureter. Postoperative chemotherapy was not given. Convalescence was uneventful and fifteen months after the operation she is alive with no recurrence or metastasis.

The objectives of our study were to (1) assess the outcomes resulting from the use of sonography in patients referred to our institution's ultrasound laboratory for an elevated serum creatinine level and (2) determine relevant clinical parameters in these patients to better triage them for sonography. We retrospectively identified and determined outcomes of 60 patients (20 women, 40 men; mean age, 61 years; range, 33 to 100 years) referred for sonographic evaluation because of an increased serum creatinine level (> or = 1.3 mg/dL). Ultrasound findings (hydronephrosis, renal size, and echogenicity) were correlated with clinical outcomes. Twenty-one patients (35%) had hydronephrosis, with 14 of these patients confirmed to be obstructed and five not obstructed. Two were indeterminate for obstruction. Eight of 14 obstructed patients were successfully treated. All obstructed patients had a suggestive history for obstruction with at least one of the following: pelvic mass (n = 9), stone disease (n = 4), or flank pain (n = 1). Only 2 of 44 patients, who were not obstructed, had any of these parameters (statistically significant difference, P < 0.0001). Thirty of the patients, who were not obstructed, had more likely alternative causes for renal failure, with sonography having no effect on patient management. Renal size and echogenicity had little effect on patient management. Sonography was efficacious in guiding management in patients with a suggestive history for obstruction (eg, pelvic mass, stone disease, or flank pain) but not in most patients who had no suggestive history and other more likely causes for renal failure.

A case of mucinous adenocarcinoma of the renal pelvis and ureter presenting as chronic flank pain, calculus, and hydronephrosis in an immigrant from India is presented. A literature review reveals a high frequency of reporting this otherwise rare tumor in India and suggests an inflammatory, environmental, or dietary etiology.

In 58 patients with acute recurrent or persistent flank pain, straight x-ray (kidney, ureter, bladder region) detected stones in the urinary tract in 50 cases (86.2%), whereas ultrasonography detected stones in the urinary tract in 55 patients (94.8%). Ultrasound also detected unilateral hydronephrosis in 20 patients (34.48%). The presence of calculus was subsequently proved by intravenous urography/surgery or spontaneous passage. Ultrasonography is safe, quick, reliable and most effective diagnostic tool in such cases in rural areas. Intravenous urogram should be reserved for cases which need surgical intervention.

The incidence of tuberculosis has risen in many parts of the world, and more attention is being focused on genitourinary tuberculosis (GT), the second most common extrathoracic form of tuberculosis. Although chemotherapy is the mainstay of treatment, ablative surgery as a first-line management may be unavoidable for sepsis or abscesses. In cases with hydronephrosis and progressive renal insufficiency caused by obstruction, renal drainage (by stenting or nephrostomy) must be performed immediately. In all other situations triple-drug chemotherapy should be undertaken for at least 6 months and stable conversion obtained before ablative or reconstructive surgery is planned. Nephrectomy or partial nephrectomy is indicated for nonfunctioning or poorly functioning kidneys, particularly if continuous flank pain or hypertension is present. Stenosis of the ureter usually can be managed by temporary stenting and adjuvant corticosteroid therapy. Today the indications for augmentation are rare, but bladder replacement may be combined with ureter replacement using segments of intestine.

Acute urinary tract obstruction, a common disease in daily practice, often requires performance of emergency intravenous urography (IVU). However, the spectrum of urographic abnormalities seen with acute obstruction has not been thoroughly addressed. The purpose of this study was to explore the IVU findings in patients with acute urinary tract obstruction. Records of 380 patients who underwent IVU in our hospital during a 6-mo period were reviewed for IVU evidence of acute urinary tract obstruction. Of the 380 patients, 53 (14%; 39 men, 14 women; average age = 43 yr) had acute urinary tract obstruction. All obstructions except one were located in the lower one-third of the ureter. The causes of acute urinary obstruction included ureteral stones in 34 (64%), ureteral edema or lucent stones in 16 (30%), neoplasms in 2 (4%), and inflammatory disease in 1 (2%). Abnormal radiologic findings were hydroureter in 46, nephropyelographic delay in 36, hydronephrosis in 35, interureteric ridge edema in 11, persistent dense nephrogram in 6, urine extravasation in 5, vicarious excretion in 1, striation in 1, and stricture in 1. Radiographic results were normal in one patient. The most common clinical indications of acute ureteral obstruction are flank pain and hematuria, and calculi are the major cause. In one-third of patients, radiopaque calculi are not detectable with IVU during acute urinary tract obstruction. A careful and thorough evaluation of the IVU should be performed in patients with clinical indications of acute urinary obstruction.

A rare case of congenital mid-ureteral stricture is reported. A 17-year-old woman was admitted with sudden onset of right flank pain. Intravenous urography demonstrated bilateral small renal calculi, left hydronephrosis and a stricture of the left ureter at the level of the pelvic brim. The diagnosis was determined as congenital mid-ureteral stricture because the ureter tapered smoothly from 25 mm to 5 mm in diameter at the stenotic site. She was successfully treated by partial ureterectomy with end-to-end anastomosis. Histopathologically, no dysplasia of muscular layer was recognized.

A clinical study was conducted on the intermittent hydronephrosis in children. Of 78 children with hydronephrosis due to ureteropelvic junction obstruction operated between 1991 and 1995, 5 had intermittent hydronephrosis. All 5 patients were boys between 6 months and 6 years of age. Presenting symptoms were intermittent flank pain and vomiting. Ultrasonography performed during pain attack demonstrated dilation of the renal pelvis in all patients. Diuretic renography demonstrated obstruction in 4 of the 5 children and deterioration of renal function on the affected side in 2. The cause of ureteropelvic junction obstruction was aberrant vessels in 2 cases, fibrous band in 1, ureteral kinking within adventitia in 1 and a ureteral polyp in 1. Postoperatively, all patients have been relieved from the pain. In summary, ultrasonography at the time of symptom attack as well as diuretic renography are useful for the diagnosis and observation of intermittent hydronephrosis.
