A 57-year-old man with Felty's syndrome had flank pain as a result of ureteral obstruction and right hydronephrosis. The obstruction was due to retroperitoneal necrobiotic granulomas typical of rheumatoid nodules.

Orthotopic ureteroceles may present with various symptoms, such as bladder irritability, flank pain, stone formation or recurrent urinary infections. When symptomatic, excretory urography often demonstrates varying degrees of hydronephrosis. We herein review a series of 12 patients in whom endoscopic ureteroneocystostomy (distal incision of the ureterocele) was performed. The procedure, and its theoretical advantages and indications are discussed. The results indicate excellent therapeutic benefit from this minimally invasive technique.

The diagnostic work-up of the urologic patient must be tailored to the presenting symptom complex, carefully selecting from the many modilities available, those most likely to establish the diagnosis and extent of the suspected lesions. Intravenous urography is the most rewarding initial procedure for many presenting symptoms, including suspected masses, pyuria, hematuria, and flank pain. Nuclear imaging is particularly effective in differentiating renal lobulations from true masses, in demonstrating parenchymal scarring in chronic pyelonephritis when the IVP is equivocal, and in assessing the decrease in perfusion and function in obstructive nephropathy when the IVP is indeterminate. It is the preferred procedure for acute renal infarction and acute tubular necrosis and has a greater sensitivity of detection for renal trauma than the IVP. Gallium-67 renal imaging appear helpful in the detection of occult pyelonephritis or interstitial nephritis. However, it cannot differentiate focal acute pyelonephritis from abscess or abscess from neoplasm. Ultrasoneography is the initial procedure of choice in the differentiation of cystic from solid renal masses and in anuria or oliguria. When a kidney fails to visualize by IVP or nuclear imaging, it can confirm or rule out obstruction. In upper tract infections, it may demonstrate renal or perirenal abscess. Although retrograde pyelography is performed less frequently in recent years, it remains extremely useful in confirming and relieving obstructive uropathy and in delineating tumors of the collecting system. Computed tomography effectively demonstrates hydronephrosis, renal abscess, tumors, and cysts and retroperitoneal involvement. More experience is needed to judge the efficiency of "dynamic" CT for the quantification of renal function. Renal angiography remains invaluable as a secondary procedure (as opposed to initial screening) in renal trauma, vascular anomalies, and in renal tumors to delineate the anatomy of the arterial supply and possible renal vein involvement.

The "Septic Kidney" usually originates from infected hydronephrosis. The clinical appearance is characterized by poor general condition, in particular shock, severe flank pain, high fever with chills, leucocytosis and often azotemia. The pathogenesis and definition are discussed on the basis of 110 cases. The various therapeutic modalities such as primary nephrectomy, conservative surgery or endoscopic instrumentation are compared and the indications defined. Conservative procedures are preferred over primary nephrectomy.

Repeated episodes of acute renal flank pain were observed in a uremic patient on maintenance hemodialysis. Computer tomography during the acute attack repeatedly showed unilateral hydronephrosis which always subsided after passage of stones. X-ray failed to visualize the non-radioopaque stones and sonography was non-contributory. The stones consisted of organic matrix and contained protein material. The present observation documents that computer tomography is valuable in establishing the diagnosis of acute ureteral obstruction resulting from non-radioopaque renal stones in dialysed patients with contracted kidneys.

A 46-year-old man who had a history of hypogonadism, bilateral hydronephrosis and huge residual urine volume during the past ten years was admitted complaining of fever and flank pain. Polyuria which was more than 4 liters per day and inability of urine concentration suggested diabetes insipidus. Magnetic resonance imaging (MRI) demonstrated a tumor which was compatible with craniopharyngioma. Tumor resection and administration of desmopressin improved polyuria and urinary tract dilatation with marked reduction of residual urine volume from 400 ml to 20 ml.

A 55-year-old woman suffered from right flank pain and had a right giant ureteral stone with hydronephrosis. Ureterolithotomy was performed. The ureteral stone was 11cm long and weighed 45gm.

A case of spontaneous rupture of the right kidney caused by a primary renal pelvic tumor is reported. A 57-year-old man complaining of right flank pain and gross hematuria was referred to our hospital in November 1992. In 1982, transurethral resection of the bladder tumor (TUR-Bt) and vesical instillation with mitomycin-C (MMC) had been performed at another hospital for recurrent bladder tumor. In 1988, the excretory urogram showed right hydronephrosis in the absence of a bladder tumor. In 1992, the excretory urogram revealed nonvisualization of the right kidney and obscurity of the right psoas muscle shadow. On the retrograde pyelogram, the upper calyx was irregular and the middle and lower calices were not clearly visualized. Selective renal arteriography demonstrated loss of continuity between the middle portion and lower poles. Right nephroureterectomy with bladder cuff was performed. The severely dilated pelvis contained a large amount of coagula and a papillary tumor. The thin renal parenchyme was lacerated at the lower pole. Histopathological findings revealed noninvasive transitional cell carcinoma. The present case represents the 6th spontaneous renal rupture caused by a renal pelvic tumor reported in Japan.

The case of a 5-year-old girl, complaining of left abdominal and flank pain, is reported. The excretory urogram and retrograde pyelography showed an obstruction located at the left upper ureter with hydronephrosis. Exploration revealed a small ureteral polyp obstructing the lumen. The polyp along with the short segment of the ureter was resected. Diagnostic and therapeutic considerations are discussed.

The presence of stones during an otherwise uneventful pregnancy is a dramatic and potentially serious issue for the mother, the fetus, and the treating physicians alike. The incidence and predisposing factors are generally the same as in nonpregnant, sexually active, childbearing women. Unique metabolic effects in pregnancy such as hyperuricuria and hypercalciuria, changes in inhibitors of lithiasis formation, stasis, relative dehydration, and the presence of infection all have an impact on stone formation. The anatomic changes and physiologic hydronephrosis of pregnancy make the diagnosis and treatment more challenging. Presenting signs and symptoms include colic, flank pain, hematuria, urinary tract infection, irritative voiding, fever, premature onset or cessation of labor, and pre-eclampsia. The initial evaluation and treatment are again similar to those used for the nonpregnant population. The most appropriate first-line test is renal ultrasonography, which may, by itself, allow the diagnosis to be made and provide enough information for treatment. Radiographic studies, including an appropriately performed excretory urogram, give specific information as to size and location of the stones, location of the kidneys, and differential renal function and can be used safely, but the ionizing radiation risks should be considered. All forms of treatment with the exception of extracorporeal shock wave lithotripsy and some medical procedures are appropriate in the pregnant patient. Close coordination by the urologist, the obstetrician, the pediatrician, the anesthesiologist, and the radiologist is required for the appropriate care of these patients.
