Clinical features have been correlated with renal function, histology and selective renal angiography in 19 patients with recurrent painless haematuria, recurrent loin pain, or both haematuria and loin pain in whom urinary infection, calculi and anatomical abnormalities of the urinary tract had been excluded. No deterioration in renal function was observed in any patient over periods of up to nine years. Although all patients showed similar glomerular changes histologically, consisting of focal and segmental mesangial thickening and proliferation and periglomerular fibrosis, mild tubular damage was more common in those with loin pain. All patients with loin pain whether or not they had haematuria, had abnormal renal angiograms consisting of focal or generalized vascular lesions sometimes associated with cortical infarcts. The possible aetiological factors are discussed with particular reference to oestrogen-containing compounds.

The usefulness of renal biopsy in investigating unexplained haematuria was assessed by a study of 33 adults referred consecutively with this syndrome. Unequivocal abnormalities were seen on light microscopy or immunofluorescence in 31 of the 33 specimens of renal tissue examined. In 18 patients deposits of IgA were present in the mesangium. Loin pain occurred in only two of the 18 patients with mesangial IgA deposits, compared with 11 of the 15 patients without these deposits. Seven of the nine women in this series had had loin pain compared with only six of the 24 men. Thus a woman with loin pain and haematuria was not likely to have mesangial IgA nephropathy but this was found in 14 of the 18 men with unexplained painless haematuria. Failure to appreciate the role of renal biopsy in the investigation of unexplained haematuria may result in unnecessary radiology, considerable morbidity, and even in unjustified nephrectomy.

Renal cell carcinoma is extremely rare in children. A case is reported here of renal cell carcinoma in a seven-year-old boy whose clinical manifestations were fever and right loin pain. Imaging studies revealed a solid mass in the right kidney and a metastatic nodule over the middle lobe of the right lung. Right nephrectomy and middle lobectomy of the right lung were performed. Pathologic examination revealed a renal cell carcinoma with predominance of clear cells. Despite Stage IV, the patient is still alive without chemotherapy and radiotherapy. It should be emphasized that renal cell carcinoma should be included in the differential diagnosis of pediatric renal solid masses, particularly in older children and adolescents.

Over a 16-year period (1973-1989), 63 renal autotransplants were performed in 59 patients for fibro-muscular dysplasia (FMD) with renal artery stenoses (42 kidneys) or aneurysms (21 kidneys). About two-thirds of the autotransplants were performed before percutaneous transluminal angioplasty (PTA) was established for clinical use. However, vascular disease at a site or type not suitable for PTA was present in 57 (90%) of the kidneys. Hypertension was the leading symptom in 56 patients, including four in whom renal autotransplantation was performed as an emergency for acute renal artery occlusion or malignant hypertension. Blood pressure returned to normal or improved in 51 (91%) and remained unchanged in five patients (9%) following autotransplantation. Three patients with renal artery aneurysm in whom haematuria and loin pain were the indications for treatment, became asymptomatic following surgical intervention. Bilateral renal autotransplantation was performed synchronously in one and sequentially in three patients. There were no operative deaths, but two kidneys were lost postoperatively in two 2-year-old children owing to renal vascular thrombosis. In the follow-up period (mean 4.3 years), one additional kidney was lost at 3 months owing to progressive FMD. Blood pressure and renal function remained stable in all other patients. Based on the excellent results achieved in this series, it is concluded that extracorporeal vascular repair and renal autotransplantation is a safe procedure for the patient as well as the kidney affected by FMD. The procedure is advocated as an alternative to in situ reconstruction in patients with renal artery disease not accessible to PTA, such as aneurysms and complex branch renal artery stenoses.

Rheumatic manifestations are common and varied in infective endocarditis. We performed a retrospective case analysis on 87 patients with 93 episodes of infective endocarditis admitted to Flinders Medical Centre over an 11 year period (1980-1990). Disabling musculoskeletal symptoms and signs were documented in 22 (25%) of the patients. Thirteen patients developed severe or moderately severe low back pain during their illness, two with radiological evidence of a septic discitis or vertebral osteomyelitis. Two patients developed polyarthralgia/arthritis, four had septic arthritis (all with acute Staphylococcus aureus endocarditis), three developed severe loin pain, two acute gout, two had severe buttock pain and sacroiliac joint tenderness and two each developed disabling jaw/facial pain, neck/scapular pain and flank pain respectively. Five patients presented initially to the orthopaedic or rheumatological unit for management of their musculoskeletal symptoms. Four of seven patients with Streptococcus bovis endocarditis demonstrated prominent low back pain supporting a previously noted association between this organism and back symptoms. Furthermore, in one patient who had three separate episodes of endocarditis involving three different organisms, florid back symptoms were only seen in the infective episode involving Streptococcus bovis.

Eleven patients with hydatid disease of the urinary tract have been seen in the last 5 years. Seven patients had cysts of the kidneys and 4 had large retrovesical hydatids. Seven of the 8 patients with renal hydatids presented with loin pain and mass. Three patients with renal communicating hydatids also presented with haematuria which was due to passing "grape skin" (hydatid membrane) in the urine. Two patients with retrovesical hydatids had bladder outflow obstruction and 2 had bilateral ureteric obstruction leading to uraemia. Eight of 11 patients had associated hydatids of other organs such as the liver (4 patients), peritoneal cavity (2) and lungs (1). Computed tomography was the most useful and specific investigation. In both renal and pelvic (retrovesical) hydatid cysts, endocystectomy with either partial excision or plication of the ectocyst is the standard treatment. In renal communicating hydatids the options are either nephrectomy (partial or total) or endocystectomy with closure of the communication. The use of cryocone and scolicidal agents is mandatory during surgery.

In a 6-year period, 9 patients were referred by their General Practitioners to the urology unit with a clinical diagnosis of renal colic but were subsequently found to have leaking abdominal aortic aneurysms (AAA). In all cases of loin pain, especially in the elderly patient, the possibility of a leaking abdominal aneurysm must be considered. If no intrinsic urological cause for the pain is found or patterns suggestive of ureteric obstruction are seen on urography, ultrasound examination of the aorta-iliac vessels should be performed. Magnetic resonance imaging (MRI) and computed tomography (CT) scans may be useful adjuncts to this investigation.

This report is a 17-year-old man with an acute renal failure who complained of nausea, vomiting, bilateral loin pain and abdominal pain after scuffle. Renal biopsy specimen obtained from the left kidney revealed acute tubular necrosis. After recovering renal function he showed extreme hypouricemia (serum uric acid, 0.6 mg/dl) and elevated uric acid clearance (62-78 ml/min). The fractional excretion of uric acid (CUA/Ccr) could not be influenced by either oral pyrazinamide or probenecid. As no other renal tubular or metabolic abnormalities were detected, it is suggested that presecretory reabsorption defect or subtotal defect in uric acid transportation was responsible for the hypouricemia in this patient.

A case of contralateral ureteral metastasis from renal cell carcinoma is reported. A 52-year-old man underwent left nephrectomy for renal cell carcinoma of November 20, 1986. He was clinically asymptomatic for 4 years 8 months after the operation. He was admitted on August 14, 1991, because of right loin pain. Right retrograde pyelography and percutaneous pyelography showed a filling defect in the right ureter at the level of L3. After the right ureter was explored, the tumor lesion of ureter was resected and end to end anastomosis of the ureter was performed. Histopathologic examination showed a metastatic clear cell carcinoma consistent with a renal primary. The contralateral ureteral metastasis from renal cell carcinoma is very rare and only 15 cases have been reported previously.

The current literature suggests that renal autotransplantation is nearly uniformly effective in controlling the severe and debilitating pain of the loin pain-hematuria syndrome (LPHS). However, we report two patients thought to have this syndrome in whom renal autotransplantation did not result in long-term control of pain. In case 1, autotransplantation resulted in immediate cessation of pain; however, the flank pain recurred 7 1/2 months later. The recurrent pain was also severe and debilitating, requiring narcotic medications for control. In case 2, autotransplantation of the left kidney resulted in chronic pain in the left pelvic area, the site of the autotransplanted kidney. In addition, the patient continued to experience chronic discomfort in the left flank and along the flank incision. One year after autotransplantation, the patient still requires multiple daily doses of narcotic medications for pain control. Our two patients represent the 13th and 14th reported patients subjected to renal autotransplantation for management of LPHS. They represent only the third and fourth reported patients with recurrence of pain after renal autotransplantation. Because studies with negative results are less likely to be reported in the literature than studies with positive results, it is possible that the literature overestimates the effectiveness of renal autotransplantation in the LPHS. To assess the true effectiveness of renal autotransplantation in LPHS, a survey of patients with LPHS who have undergone renal autotransplantation needs to be performed.
