The clinical and radiological features of pyonephrosis are reviewed, based on a consecutive series of 40 cases. There were 32 female and eight male patients, with a peak incidence in the 50-59 year age group. In 63% of cases the right kidney was involved. Almost all patients complained of loin pain and 48% had lower urinary tract symptoms. In 58% of cases a renal mass was palpable. An anaemia, pyuria and elevated blood sedimentation rate were usual. Plain films of the abdomen revealed enlargement of the outline of the involved kidney in 75%, ipsilateral absence of the psoas shadow in 63% and urinary tract calculi in 60%. At high-dose excretion urography a nephrogram was obtained in 58% of cases and a pyelogram produced in 34%. No single clinical or radiological entity emerged, there being an unbroken spectrum of disease ranging from infected hydronephrosis to xanthogranulomatous pyelonephritis. There is an increasing incidence of calculi, loss of the renal and psoas outlines and reduced renal function with increasing chronicity of disease. High-dose excretion urography is the investigation of choice since not only may the diagnosis be established but also there precise pathological state of the involved kidney. Further radiological investigation is infrequently required.

Multifactorial analysis on 395 patients revealed important factors which prolong the pyuria after transurethral prostatectomy. They were the age of the patient, anemia and leukocytosis before surgery. These are factors which relate with the defense mechanism of the patient. Local factors, such as the duration of indwelling urethral catheter, the size of the prostate or prostatic bed and preoperative infection, were not so important for prolonging the pyuria after transurethral prostatectomy. The time of the resection and weight of the prostate had an intimate relation each other, and the former was the more important factor. The use of antimicrobials probably controlled these local risk factors, thus making them unimportant in the prolongation of the pyuria after transurethral prostatectomy.

Diagnostic criteria of analgesic nephropathy with well-defined sensitivity and specificity are not available. During a 2-year period all new patients (n = 273) starting renal replacement therapy in 13 Belgian dialysis units were investigated aiming to select diagnostic criteria of analgesic nephropathy with acceptable performance. Using several interview techniques, a history of analgesic abuse was found in 31% of the patients. Analgesic abusers presenting a clear non-analgesic-related renal diagnosis were excluded from analysis (n = 25). Comparing the remaining abusers (n = 60) and patients without a history of analgesic abuse (n = 188) it was found that renal imaging investigations (sonography plus tomography), showing a decrease in length combined with bumpy contours of both kidneys, presented a sensitivity of 90% and a specificity of 95%. The additional finding of signs of renal papillary necrosis resulted in an overall sensitivity of 72% and a specificity of 97%, giving a positive predictive value of 92%. Other signs frequently mentioned in the literature (hypertension, anaemia, sterile pyuria, bacteriuria, proteinuria) showed insufficient sensitivity and/or specificity to be of help for diagnosing analgesic nephropathy in end-stage renal failure (ESRF) patients starting renal replacement therapy.

A 17-year old-male presented with a 6-week history of weight loss, lassitude and calf pains. On examination he was very pale. Laboratory tests showed a very high erythrocyte sedimentation rate (155 mm in the first hour), anaemia (haemoglobin 10.1 g/dl), and a raised serum creatinine of 1.54 mg/dl. Microhaematuria (5-10 erythrocytes/microliter) and pronounced pyuria (500 leucocytes/microliter) were present, but the urine was sterile and there was no increase in albumin excretion. The serum IgG was raised to 75.7 g/l, suggesting an autoimmune disorder. Anti-nuclear antibodies (titre 1 : 1920) and anti-double-stranded DNA antibodies (31 U/ml) were present, while the serum complement C4 was decreased to 0.11 g/l. Renal histology showed an interstitial nephritis without glomerular involvement, while the bone marrow showed vasculitis accompanied by a prominent plasma-cell infiltrate. A diagnosis of interstitial nephritis associated with systemic lupus erythematosus was made, with asymptomatic cardiac and hepatic involvement. Renal function recovered rapidly with prednisolone therapy (initial dose 2 mg/kg.d). While glomerulonephritis is the most common lupus-associated renal disorder, isolated interstitial nephritis may occur in some cases, often with an absence of proteinuria.

We have reviewed our experience with acute interstitial nephritis (AIN) in pediatric patients over the 3-year period from 1985 to 1988. We encountered 7 new cases of AIN in this interval and it was seen in 7% of kidney biopsies performed during this time of study. The clinical presentation was very nonspecific and included fever (100%), gastrointestinal complaints (57%) and rash (28%). Laboratory findings on admission included elevated erythrocyte sedimentation rate (100%), anemia (70%), pyuria (57%) and abnormal renal ultrasound (86%). Associated systemic diseases were observed in 4 patients. AIN was severe enough to necessitate treatment with hemodialysis in 42% of the cases. Corticosteroid therapy was used in 6 patients with a favorable response in all but 1 case. While 6/7 patients manifested complete recovery, 1 adolescent who may have had pre-existing renal disease had persistent chronic renal failure (estimated GFR, 25 l/min/1.73 m2). We have concluded that: (1) AIN is a relatively common disease in pediatric practice; (2) it can be severe enough to necessitate dialysis therapy, and (3) AIN often occurs in children with systemic disorders that may be associated with immunologic disorders.

Autosomal dominant polycystic kidney disease (ADPKD) is the commonest hereditary nephropathy. We collected 92 cases in VGH. Diagnosis was confirmed by intravenous pyelogram, renal sonogram, or renal CAT scan. The incidence of having positive family history was just only 28.3%. Patients were diagnosed at the mean age of 54 +/- 11 years (26-74 years). The common clinical findings were hypertension (73.9%), abdominal mass, proteinuria, anemia, azotemia, abdominal or back pain and pyuria in orders. Hypertension might present in the early stage with normal renal function (near 40%). Polycystic liver was the major extrarenal lesion (57.6%), but the incidence of abnormal liver function was only 10.1%. Enlarged kidneys were not always palpable, even at end stage of renal function (mean age 56 +/- 9 years, 89.4% kidney palpable). Patient's urine amount was usually nonoliguric, even in uremic stage (82.9%). Sepsis was the first cause of death. Cardiovascular disease and uremia were followed in sequence. Their expired mean age was 61 +/- 7 years (53-74 years).

We describe a patient with hematuria, pyuria, eosinophiluria, decreased renal function, and severe anemia that developed while she was receiving chronic therapy with griseofulvin for onychomycosis. We offer evidence that griseofulvin can cause an isolated erythroid hypoplasia and possibly an allergic interstitial nephritis. This is the first documented case of the above entities induced by the agent. We would recommend, based on our report, that otherwise healthy patients, when maintained on the drug for extended periods of time, have periodic determinations of renal function and hematologic status. As drug-induced erythroid hypoplasia typically occurs after a relatively long period of dosing, it may be prudent in certain individuals to monitor the CBC at approximately bimonthly intervals after initiation of therapy. Recommendations regarding monitoring of renal function are more difficult, as acute allergic interstitial nephritis can occur after either short- or long-term exposure to certain drugs.

The outcome of postsurgical pyuria in benign prostatic hypertrophy was studied in 87 patients, and the factors that might affect the outcome were determined. No significant differences were found between operation method and duration until normalization of pyuria, which was 75.5 +/- 46.0 days for transurethral resection of the prostate, 72.7 +/- 30.6 days for suprapubic prostatectomy and 69.3 +/- 32.7 days for retropubic prostatectomy. Prognostic factors were statistically analyzed preoperatively, at operation, and postoperatively. The definite prognostic factors were preoperative diabetes mellitus, preoperative pyuria, preoperative bacteriuria, and postoperative hypoproteinemia. The probable prognostic factors were old-age, preoperative indwelling catheters, heavy prostate tissue, postoperative bacteriuria, postoperative anemia and postoperative complications.

Last year, we reported that human papilloma virus type 16 genome (HPV 16 genome) was detected in a case (S.Y.) of bladder carcinoma in situ (bladder CIS) (Cancer Res., 1988). Since then, a number of bladder tumors other than CIS were searched for HPV genome. However, no HPV genome was detected in the bladder tumors. From the results, we consider that HPV may not have a relation with all types of bladder tumor but with only a part of it. In the current report, the case (S.Y.) is presented more precisely than before, in particular on the characteristic bladder lesion. The patient was a 40-year-old female with immunodeficiency and anemia who was referred from a hospital with a complaint of asymptomatic pyuria. Cystoscopic examination revealed a bladder tumor, well-demarcated, white and velvety lesion with slight elevation. On November 25, 1987, she underwent total cystectomy, resection of the anterior vaginal wall and of a part of vulval skin, and ileal conduit formation. Postoperative course was stormy because of bleeding from the wounds and thrombophlebitis in the right femoral vein. In spite of the episodes, she eventually recovered and was discharged 2 months later. However she was readmitted 9 months later due to severe anemia which was ascribed to acute myelogenous leukemia. She is now on cancer chemotherapy for leukemia.

50 children with Kawasaki disease were seen between September 1983 to March 1988. Their ages ranged from 3 months to 10 years with a mean age of 25 months. Male to Female ratio was 2.3 to 1. The diagnosis of Kawasaki disease was made between the fourth to fifteenth day of illness. Marked thrombocytosis, raised erythrocyte sedimentation rate, leucocytosis, mild anemia and sterile pyuria were common features. All patients had a normal ECG and chest X-ray. 2D echocardiogram was done in the sub-acute phase of the illness in every patient. Sixteen patients (32%) had coronary artery dilatation. Thirteen of these had serial 2D echocardiograms done over a period of more than one year. Twelve had echocardiographic resolution of the coronary lesion within 18 months of follow up. Patients with coronary artery dilatation were significantly younger. All had full clinical recovery with aspirin therapy. Kawasaki disease afflicts mostly young children and can present as a diagnostic problem. Coronary artery involvement is common, and except for age, it is not predictable by any clinical or laboratory parameter. Serial echocardiographic examinations are necessary in the management of these patients.
