During pregnancy, dilatation of the urinary collecting system is very common. Acute hydronephrosis is one of the most common causes of severe flank pain in pregnancy. Severe complications of hydronephrosis of pregnancy, such as pain, renal failure or a ruptured collecting system, occur very occasionally. A rare case of spontaneous rupture treated conservatively is presented.

The proliferation of imaging methods for the kidney and urinary tract, combined with advances in technology and the introduction of new techniques, has created uncertainty in selecting the most efficient method for evaluating many problems encountered in clinical medicine. The main advantage of nuclear medicine lies in demonstrating the pathophysiology involved. Recent developments in Doppler ultrasound and magnetic resonance imaging with different pulse sequences and paramagnetic contrast agents also have shown promise for imaging physiological processes. However, there is little literature to support their advantage over nuclear medicine procedures in many common clinical situations. The complementary nature of nuclear medicine studies in the imaging evaluation of hydronephrosis, renal artery stenosis, flank pain, renal mass, pyelonephritis, and the transplant kidney is reviewed.

A 12-year-old boy presented with fever and flank pain bilaterally. Intravenous pyelogram revealed multiple stones and hydronephrosis in the right kidney and an obstructive filling defect at the left upper ureter. Exploration of the left ureter revealed a fibroepithelial polyp. The presented case was an example of the unreported association between fibroepithelial polyp and contralateral nephrolithiasis.

A 68-year-old man visited his home doctor with the chief complaint of left flank pain. Abdominal ultrasonography revealed left hydronephrosis and space occupying lesion in the right kidney. He was referred to our hospital because of suspected left ureteral stone and for further examination. Drip infusion pyelography revealed a left ureteral stone and retrograde pyelography showed extrinsic compression and deformation of the right pyelogram. A computed tomography showed a heterogeneous solid mass, 7 x 4 cm in size, compressing the pelvicocalyceal system and growing out of the kidney. Right radical nephrectomy was performed under the diagnosis of renal cell carcinoma. The pathological diagnosis was leiomyosarcoma. Seventy-five cases of renal leiomyosarcoma have been reported in the Japanese literature and this is the third case as an incidental tumor. Because of the absence of the characteristic diagnostic signs, this malignant tumor can present diagnostic difficulty. The diagnostic problems and clinical features of renal leiomyosarcoma are discussed.

Inverted growth of transitional cell carcinoma in the ureter is reported. A 71-year-old female visited us for right flank pain and gross hematuria. Hematuria from the right ureteral orifice was found by cystoscopy. Intravenous pyelography revealed right hydronephrosis and a filling defect in the right ureter, but the filling defect moved to the lower ureter. Computerized tomographic (CT) scan demonstrated a tiny lesion in the right ureter. Under a tentative diagnosis of right ureteral tumor, flexible fiberoptic ureteroscopy was performed. As a pedunculated tumor with a smooth surface was found, biopsy was performed. Since pathological examination showed malignancy, right nephroureterectomy was performed. Histological diagnosis was transitional cell carcinoma, grade 1. Cancer was covered by normal transitional epithelium, and developed inverted growth. This is a rare case of inverted growth of the transitional cell carcinoma in the ureter.

Congenital ureteral valves have not been a well recognized condition for the cause of ureteral obstruction. In our first case a 21-year-old male presented with left flank pain. Intravenous urography showed left mild hydronephrosis due to upper ureteral obstruction. Partial ureteral resection and re-anastomosis was performed. Histology demonstrated mucosal folds with smooth muscle. In our second case a 12-year-old boy presented with left flank pain. Retrograde pyelogram showed a fold-like filing defect which suggested ureteral valve. Endoscopical valve resection through nephrostomy was performed. Optimal management and diagnostic difficulties were discussed.

Between August 1982 and May 1988, 503 patients underwent construction of a continent ileal reservoir (Kock pouch) for cutaneous urinary diversion at our university. Stenosis of the afferent antireflux valve resulted in upper urinary tract obstruction in 11 patients (2%). In addition, 2 patients underwent Kock pouch diversion elsewhere and upon referral to our institution they had afferent valve stenosis. To date 13 patients have been identified with this problem. Hydronephrosis was present in 100% of the functional kidneys in these patients. Radiographs of the Kock pouch were uniformly normal without evidence of reflux or other pathological condition. The most common presenting symptom was flank pain in 7 patients (54%) and the most common presenting sign was creatinine elevation above baseline in 7 (54%). Infections recurred with or without sepsis in 5 patients (38%). Ureteroileal anastomotic strictures were not present in any patient. The interval from creation of the Kock pouch to the diagnosis of stenosis ranged from 2 to 75 months (mean 39). All patients underwent endoscopic evaluation of the Kock pouch confirming stenosis of the afferent antireflux valve, and subsequent mechanical dilation of the stenotic valve. Dilation procedures were repeated in 6 patients (46%), 4 of whom subsequently required open surgical revision of the afferent valve. Of these patients 3 are clinically stable and 1 died of the primary malignancy. The remaining 2 patients are clinically and radiographically stable after multiple dilations. Of the 7 patients (54%) requiring only a single dilation 6 are clinically stable and 1 died of the primary malignancy. Stenosis of the afferent antireflux valve of the Kock pouch, previously unreported to our knowledge, is a rare late complication leading to flank pain, hydronephrosis, recurrent infection and elevation of serum creatinine levels. Approximately 50% of the patients respond to a single dilation of the nipple valve. However, most patients who require repeat dilation will need open surgical revision.

We treated 13 patients with unilateral ureteropelvic junction obstruction by percutaneous endopyelotomy, and they were urodynamically evaluated by the Whitaker test and diuresis renography, in addition to excretory urography (IVP). Surgery was uncomplicated in all patients except 1 who required repeat incision 4 weeks later. Obstruction was diagnosed preoperatively by the Whitaker test and diuresis renography in 10 cases, and by IVP in 13. Postoperatively, all 10 patients (100%) with a positive Whitaker test were free of obstruction with a significant reduction in the relative renal pelvic pressure from 35.0 to 8.1 cm. water (p < 0.01). Diuresis renography revealed no obstruction in 8 patients (80%) and persistent obstruction in 2. IVP demonstrated reduced hydronephrosis in 8 of 13 patients (62%) 12 weeks after surgery and in 11 of 13 patients (85%) 19 months later. However, a marked reduction in renal pelvic size was noted in only 3 patients (23%). Flank pain disappeared in 10 of 11 patients (91%) postoperatively. Overall, surgery was successful in 11 of the 13 patients (85%). Percutaneous endopyelotomy was effective in relieving obstruction at the ureteropelvic junction with minor morbidity. The Whitaker test was more sensitive for evaluating the results of surgery than diuresis renography and IVP, although diuresis renography appears to be useful in followup evaluation of hydronephrosis.

A case of double inferior vena cava associated with congenital hydronephrosis is reported. A 6-year-old girl was referred to our hospital with the chief complaint of severe left flank pain of sudden onset which occurred after she fell down some steps. Abdominal computerized tomographic (CT) scan revealed a huge perinephric urinoma, severe left hydronephrosis with obstructive atrophy and double inferior vena cava. Left nephrectomy was performed under a diagnosis of traumatic rupture of the left renal pelvis associated with left congenital hydronephrosis and double inferior vena cava. Rupture of the renal pelvis and ureteropelvic junction obstruction with severe parenchymal thinning were found. The postoperative course was uneventful. Double inferior vena cava is a relatively rare anomaly and most cases in recent years have been incidentally found by ultrasonography and CT scan. Urologists should keep in mind the possibility of this anomaly of the inferior vena cava, especially when reforming left nephrectomy.

A sixty-year-old woman visited our hospital with a complaint of left flank pain. Laboratory data showed a high level of serum CA19-9. Computerized tomography and ultrasonography revealed left hydronephrosis and hydroureter. No tumors were found in the liver, pancreas, gallbladder, gastrointestinal tract or genitourinary tract. The serum SPan-1 antigen level was elevated to 250 U/ml, and the serum CA19-9 level was also elevated to 580 U/ml. Since urological malignancy was not excluded from these findings, left nephroureterectomy was performed. Pathological findings revealed chronic inflammation, and malignant cells were not found in the resected specimens. Although high levels of SPan-1 antigen and CA19-9 have been reported in benign diseases, both are usually less than 100 U/ml. In this case, serum SPan-1 antigen and CA19-9 levels were extremely high (more than 1,000 U/ml). Since the serum SPan-1 antigen and CA19-9 levels were gradually reduced to normal levels within 4 months after the operation, a possible explanation for the high levels of the two tumor markers is hydronephrosis in the left kidney. We report this interesting hydronephrosis associated with high levels of serum SPan-1 antigen and CA19-9.
