The present study demonstrates that renal tubular unresponsiveness to aldosterone, without associated hyperkalaemia, is present in children with acute pyelonephritis. We studied 32 children with a diagnosis of acute pyelonephritis established by high fever, flank pain/tenderness, increased blood levels of C-reactive protein and significant Escherichia coli growth in the urine culture. Renal tubular function tests and determinations of plasma renin activity and aldosterone concentration were performed at diagnosis (study 1), after three days of iv gentamycin (study 2) and after 21 days of antibiotic therapy (study 3). Findings were compared to those present in 32 normal children of similar age. Despite normal plasma potassium concentration, fractional potassium excretion and transtubular potassium concentration gradient were significantly decreased in studies 1 and 2, becoming normal in study 3. Decreased renal potassium excretion coexisted with increased values for plasma renin activity and aldosterone concentration. In study 3 these hormones remained elevated only in patients with scarred kidneys. The functional alteration present in acute pyelonephritis may be directly caused by the interstitial inflammation or be mediated by some E. coli endotoxin.

We treated 19 selected patients with calculi in 21 caliceal diverticula with extracorporeal shock wave lithotripsy (ESWL). By limiting this treatment to patients with relatively small (less than 1.5 cm.) calculi associated with a radiographically patent diverticular neck, a stone-free state was initially achieved in 11 patients (58%). Of 14 patients with flank pain before ESWL 12 (86%) were rendered symptom-free or markedly improved, often independent of a stone-free state. Extended followup in 13 patients for 12 to 49 months (mean 23.8 months) after ESWL revealed recurrent stones or stone growth in only 1. Although pain relief has remained constant for those initially rendered symptom-free, recurrent infection has been documented in 6 (67%) of 9 patients with infection before ESWL. We conclude that ESWL for selected patients with calculi in caliceal diverticula can achieve a relatively high initial stone-free rate and that recurrent stones may not be inevitable. Treatment in this setting also may provide long-term symptomatic relief that is often independent of a stone-free state. However, recurrent infection is not unusual, especially when associated with residual calculi. Considering the relatively noninvasive nature of this approach, ESWL should be considered an acceptable form of primary management for selected patients with calculi in caliceal diverticula.

A total of 50 patients--37 female and 13 male--with an average age of 50 +/- 27 years (23-86 years), suffering from rim-calcified gallbladder stones, underwent extracorporeal shock-wave lithotripsy (ESWL), using an ultrasound-guided overhead module of Lithostar Plus (Siemens Company). The total number of stones was 87, with an average diameter of 16 +/- 7 (7-38) mm. 29 patients had a solitary stone, 13 had two and 8 patients three or more stones. All patients received adjunct medication of 10 mg/kg body weight chenodeoxycholic and ursodeoxycholic acid 14 days prior to ESWL as a single bedtime dose. An average number of 5,300 +/- 2,200 shock waves (1,200-15,000) was applied for stone disintegration. The corresponding energy amounted to 750 bar. 29 patients needed one, 21 two or more treatments. After ESWL a variety of clinical abnormalities was observed: flank pain (15%), transient microhaematuria (33%) and transient macrohaematuria (2%). Subsequent to ESWL 5 patients suffered from complications such as biliary obstruction 3 weeks to 9 months after treatment and had to undergo ERCP. Three times endoscopic papillotomy was performed to remove stones from the common bile duct. Up to now 4 patients have undergone cholecystectomy: acute cholecystitis (n = 3), recurrent colicky pain (n = 1). 20 patients have been followed up over a 12-month period; 12 of them are completely free of stones and fragments.

Two college students who developed reversible acute deterioration in renal function following binge drinking of beer and the use of nonsteroidal antiinflammatory drugs (NSAIDs) are reported. Both patients presented with back and flank pain with muscle tenderness, but showed no evidence of overt rhabdomyolysis. The first case had marked renal failure, with a peak serum creatinine reaching 575 mumol/L (6.5 mg/dL), and acute tubular necrosis was documented by renal biopsy. The second case had only modest elevation in serum creatinine, and renal function rapidly improved on rehydration. The contribution of the potential muscle damage associated with alcohol ingestion to the changes in renal function in these two cases is not clear. However, the major mechanism for the acute renal failure was thought to be related to inhibition of renal prostaglandin synthesis in the face of compromised renal hemodynamics secondary to alcohol-induced volume depletion.

A case of retroperitoneal xanthogranuloma is reported. A 51-year-old man was referred to our hospital for the evaluation and treatment of right flank pain and hydronephrosis. Intravenous urography (DIP) and retrograde pyelography revealed the stricture in the middle portion of the right ureter. Ureteroscopy revealed no mucosal lesions. Computed tomography revealed the paraureteric mass lesion. Partial ureterectomy, mass resection and uretero-ureterostomy were performed. Then a double J stent was left in place for 6 weeks. The stricture was due to a yellowish mass adhered to the right side of the ureter. The resected mass measured 1.0 x 2.0 x 1.0 cm. The histopathological diagnosis was xanthogranuloma. The patient is in good health without recurrence 4 months after the surgery.

A case of renal vein thrombosis in a seventy-five year old female was reported. She complained of severe left flank pain. The symptoms and signs resembled obstruction from a ureteral calculus. The kidney-ureter-bladder X-ray showed a calcification in the pelvic cavity. She was admitted under the initial diagnosis of left ureteral stone. The venous phase of renal arteriography revealed venous collaterals (ureteric vein and gonadal vein). Selective renal phlebography demonstrated a radiolucent area. Warfarin, 6 mg orally daily, has been administered for a year. It has effectively prevented subsequent emboli. This was a rare case of renal vein thrombosis in an old patient, because it was not associated with nephrotic syndrome or thromboembolic state and because it presented as sudden onset.

Three cases of spontaneous peripelvic extravasation after the operation of rectal cancer are reported. In case 1, a 65-year-old female complained of left flank pain one month after high-anterior resection for rectal cancer. Drip infusion pyelography (DIP) and retrograde pyelography (RP) showed extravasation from the left renal pelvis. The ureteral stent was indwelled, and the extravasation showed remission. In case 2, a 55-year-old female complained of left lumbago 6 months after Miles' operation for rectal cancer. DIP showed extravasation from the left renal pelvis. The same findings were confirmed on the repeated DIP after 10 days. The ureteral stent was indwelled, and the extravasation was cured. In case 3, a 69-year-old male complained of left flank pain and left abdominal tumor 10 months after Miles' operation for rectal cancer. DIP and RP showed extravasation from the right renal pelvis, and computed tomographic (CT) scan showed urinoma formation. Drainage of the urinoma was performed and the ureteral stent was indwelled. The urinoma and the extravasation was cured. We emphasized the usefulness of indwelling the ureteral stent for the conservative management of spontaneous peripelvic extravasation caused by a malignant tumor, and a discussion of the relevant literature follows.

Focal idiopathic renal arterial dissection (RAD) is a rare event. Nevertheless, a RAD should always be considered in the differential diagnosis in patients with flank pain or acute abdomen, since only an immediate diagnosis and correction can guarantee the maintenance of kidney function. Early operation is also necessary because other clinical pictures with a similarly dramatic clinical course and similar symptoms can likewise only be treated surgically. These include a renal arterial aneurysm with endo-aneurysmatic thrombus and poststenotic dilatation in fibromuscular dysplasia. We describe the case of an isolated idiopathic RAD which could only be diagnosed in the context of abdominal pain symptoms. Clinical, pathophysiological and therapeutic aspects of RAD are discussed with reference to the case report and the international specialist literature.

During the study of chronic anemia in a 38-year-old woman, a nonfunctioning left kidney due to multiple asymptomatic ureteral calculi was found on excretory urography. She had self-limited episodes of left flank pain 10 years previously. Antegrade pyelography through the nephrostomy tube and computerized tomography showed a pyonephrotic renogastric fistula on that side.
