Pathophysiological characteristics and long-term prognosis were studied retrospectively in 69 malignant hypertensives associated with grade III or IV retinopathy and the diastolic blood pressure greater than 120 mmHg. Thirty three (48%) cases had essential hypertension (EHT) as the underlying disease, 26 (38%) as chronic glomerulonephritis (CGN), and the remaining 10 (14%) as others including chronic pyelonephritis, renovascular hypertension, hydronephrosis, multiple calyceal diverticula, and unknown original disease. The role of the renin-angiotensin system in malignant hypertension was investigated by measuring plasma renin activity (PRA) and determining the blood pressure response to angiotensin (ANG)II antagonist, (Sar1, Ile8) ANG II. Basal PRA was significantly higher in the EHT group than the CGN group, and the ANG II antagonist-induced reduction of blood pressure was only evident in the former group. The regression analysis revealed that PRA was linearly correlated with both mean blood pressure (MBP) and serum creatinine prior to antihypertensive treatment in the EHT group but not in CGN patients, although there was inverse correlation between PRA and serum sodium in both groups. Therefore, the renin-angiotensin system seems to play a significant role in elevating blood pressure and deteriorating renal function in malignant hypertension developed from EHT, while it is less important in that from CGN. The 5-year survival rate was 90% in total 69 patients with malignant hypertension, while the 5-year renal survival rate defined as the probability of surviving without maintenance hemodialysis was 37%, indicating that the treatment with hemodialysis as well as antihypertensive drug therapy contributed to an improvement of prognosis of malignant hypertension. The EHT group showed a poor prognosis for life compared with the CGN group, while in the latter group most patients rapidly developed endstage renal failure. Although the pretreatment serum creatinine levels were matched, the renal function more rapidly deteriorated after development of malignant hypertension in the CGN group than did in the EHT group, indicating renal survival rate to be shorter in the former group. Hence, underlying diseases may affect the long-term prognosis of malignant hypertension. The results obtained from this study suggest that the pathophysiological characteristics of malignant hypertension are different and its long-term prognosis is varied by underlying diseases such as EHT and CGN.

We report the results of clinicopathological and histochemical studies on 64 renal adenomas found in 22 patients. We selected typical renal adenomas for these studies, discarding borderline lesions. The ages of the patients ranged from 42 to 84 years, with an average of 61 years. Male to female sex ratio was 6.3:1. The background conditions included renal cell carcinoma, long-term dialysis, chronic glomerulonephritis, pyelonephritis, hydronephrosis and polycystic kidney. The sizes of the tumors ranged from 0.1 to 2.3 mm in maximum diameter, with an average of 0.9 mm. All the tumors were located in the cortex, especially in the superficial one-third. The cytoplasm of the tumor cells was predominantly eosinophilic, and the tumor structure was predominantly papillary. Histochemical study of 19 adenomas from 13 patients demonstrated that all of the adenomas from 13 patients demonstrated that all of the adenomas were positive for EMA, and for at least one marker of the distal tubulus, i.e., DBA, PNA, SBA and PKK1, and that 9 adenomas were positive for at least one marker of the proximal tubulus, i.e., LM1 and LTA. Renal adenomas had predominant histochemical features of the distal tubulus, suggesting differentiation to a distal tubulus-like histology.

After initial scepticism about its reality and despite a few disagreements, many authors now recognize the ovarian vein syndrome as a separate clinical entity, secondary to ureteral obstruction caused by dilation of the ovarian veins, which may cause lumbar pain, recurring pyelonephritis and/or lithiasic complications. The right side most frequently is affected because anatomical configuration of the right ureter is more susceptible to compression, and in fact, pregnancy appears to be an essential initiating or exacerbating factor. Thus, this anomaly might explain why painful and infectious manifestations and hydronephrosis so often develop on the right side (in over 95 p. cent of cases) during pregnancy. Its diagnosis thus must be known to be able to envisage its possible onset, by taking a careful history, and may be confirmed by certain radiological examinations. The latter, as well as treatment, depend on whether or not the patient is pregnant, its term, as well as severity of symptoms. Hence, erroneous diagnoses and incorrectly oriented surgical procedures may be avoided, while appropriate therapy is effective.

A case of right pyelonephritis with hydronephrosis complicating relapsing acute pancreatitis and right pararenal phlegmon formation is presented. Hydronephrosis is a reportedly rare complication of extrapancreatic inflammation; the only 6 previous cases involving the right side are reviewed. The present case report, to our knowledge, is the first to describe clinical and laboratory evidence of pyelonephritis secondary to partial obstruction of the right upper renal tract by an extrapancreatic phlegmon. The clinician caring for patients with acute pancreatitis should be aware of this important complication, since the presentation of pyelonephritis-flank pain and fever--could erroneously be attributable solely to the pancreatitis.

8 patients, 2 men and 6 women, 42 to 67 years of age, with bilateral multiple cysts of the renal sinus are described. 3/6 patients had macroscopic hematuria, pyelonephritis, 5/8 patients were with arterial hypertension and 4/8 patients were with renal failure. All patients were examine by ultrasound once more after a greater diuresis was achieved in order to differentiate from hydronephrosis. The isotopic nephrographic curves were normal in 2/8 patients and were disturbed in the remaining 6 patients. Hydronephrotic type curves were not found. Urography was performed to 4 of the patients and in 2 of them the diagnosis was polycystosis and in the other 2 patients it was bilateral parapelvic cysts. Possible mistakes in the diagnosis of bilateral parapelvic cysts are discussed. The reported cases with superimposed pyelonephritis and renal failure point to the need of prophylactic medical examinations of such patients.

From 1980 to 1988 235 koalas were necropsied and 67 were found to have urinary tract disease. Six affected koalas out of 48 were derived from wildlife parks around Sydney while 61 of 187 were derived from free living populations on the central and north coasts of New South Wales. Sixteen had cystitis alone, 5 had cystitis and associated renal disease only, 16 females had cystitis with genital disease, 23 had urinary disease in combination with other systemic disease and 7 had renal disease only. Overall 49 animals had cystitis (30 females and 19 males; 47 being free living) with 12 of these having renal extension (all free living). Cystitis tended to be active but chronic while associated renal disease was mainly designated as hydronephrosis and pyelonephritis. Other forms of renal disease included lymphosarcoma, oxalate nephrosis, acute and chronic nephritis, and microabscessation related to septicaemia. Female genital disease associated with cystitis was commonly vaginitis and metritis. Paraovarian cysts were detected with and without metritis. Other diseases occurring with urinary tract disease included conjunctivitis, dermatitis/stomatitis, pneumonia and hepatic disease. The higher prevalence of urinary tract disease in free living koalas, especially cystitis, is in contrast to captive koalas and may reflect the interaction between disease cause and habitat.

Ninety-six children, aged 4 to 14, with congenital obstructive uropathies were subjected to 131I-hippuran renography, followed by mathematical processing of renographic curves, the measurement of blood mean molecular levels, and blood and urinary immunochemical tests before, and 1 month as well as 1 year after surgery. Intraoperative renal biopsy was taken from 20 patients with unilateral hydronephrosis. Latent chronic renal failure (CRF) was identified where a deficiency of total renal clearance of 131I-hippuran (20 to 56%) was combined with a rise in blood mean molecules from 0.3 to 0.41 conventional units at 254 nm. Latent CRF was detected in 40 of 64 children with unilateral uropathy and in all 32 patients with bilateral uropathy. In patients with unilateral hydronephrosis, the presence of CRF was unrelated to the morphological pattern of pyelonephritis in the affected kidney. Children with latent CRF showed high levels of urinary IgG and albumin and blood mean molecules. One year after the operation, renal function improved in patients whose contralateral kidney had no secretory deficiency. One year after surgery, renal reabsorption mechanisms tended to recover in CRF-free patients only. The clinical pattern of latent CRF and its elimination following surgery were unrelated to roentgenologic markedness of hydronephrosis and VUR, but were dependent on the recovery of compensatory mechanisms in the contralateral kidney. By the end of the first postoperative year, latent CRF was diagnosed in 31% of children with unilateral hydronephrosis (as compared to the preoperative 68%), 43% (vs. the preoperative 60%) of children with unilateral VUR, and in 44% (vs. the preoperative 50%) of patients with unilateral neuromuscular ureteral dysplasia.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a rare case of anomalous inferior vena cava (IVC) in a 46-year-old woman hospitalized for the examination of right hypofunctional kidney. She had no history of trauma or pyelonephritis and there were no abnormalities in laboratory findings except serum creatinine value. Excretory urography showed no excretion of contrast medium from right kidney and retrograde pyelography revealed moderate hydronephrosis of right kidney but the obstruction of the ureter was not recognized. Abdominal computed tomographic scan showed a total trace of IVC and inferior venacavography demonstrated complete obstruction of the IVC from its origin with collateralization of upper lumber veins and vertebral veins. Surgical exploration was performed and demonstrated that IVC was a trace from the postrenal segment to hepatic segment. Two right renal veins were draining into the upper lumber vein and the right ureter was compressed slightly by lower renal vein, dilated ovarian vein and fibrotic connective tissue.

From 1973 through 1986, 166 consecutive renal transplants were performed in 143 patients. Urological complications included ureteral leakage/obstruction/necrosis, urinary tract infection, pyelonephritis, pelvic lymphocele, pelvic abscess, pelvic hematoma, infected hydrocele, bladder calculus, labial edema, renal artery/segmental stenosis, hydronephrosis, urinary incontinence, renal allograft malrotation and kidney rupture. Management options and preventive measures to avoid some of these dilemmas are highlighted.
