A group of 21 patients with hydronephrosis but normal bladders had their upper urinary tract pressures monitored while perfusing the affected kidneys through a fine bore nephrostomy tube, initially with the bladder on free drainage and subsequently during bladder filling. In 7 patients the renal pelvic pressures were altered by bladder filling and loin pain was reproduced in 4. It was concluded that with high upper tract flow rates, vesical filling can affect upper tract dynamics and this should be considered when evaluating patients with loin pain or potential obstructive uropathy.

In acute "primary" pyelonephritis (APP), kidney infection occurs despite normal urinary tract morphology. Typical features of APP are spiking fever and chills, loin pain, pyuria, bacteriuria, isolation of uropathogenic strains of E. coli, and specific renal CT scan images. APP may be atypical when lacking pain, or fever, or when urine cultures are negative, or when urinary bacteria do not exhibit characters of uropathogenicity, or when CT scan examination is negative. Such atypical features entail loss of time in diagnosis, and thereby delayed treatment and increased risk of cortical scar formation. However, they are virtually never observed simultaneously in a given patient.

Methotrexate (MTX) is a drug widely used in the treatment of patients with malignant disease. Its well-known side effects include myelosuppression, mucositis and renal damage. These problems are primarily dose-related, tending to occur more frequently when high doses (greater than 1 g/m2) are given. We present four cases in whom severe renal and mucosal toxicity occurred with intermediate doses (200 mg/m2) of MTX despite folinic acid rescue. Possible reasons for this occurrence are discussed and means of avoiding such toxicity are suggested. Three of four patients developed severe loin pain within a few hours of injection; the significance of this symptom in relation to subsequent renal toxicity has implications for early recognition of the problem.

Between 1985 and 1987 102 children, age 0-14 years, presented with a first acute symptomatic E. coli urinary tract infection. Investigations included early 99mtechnetium dimercaptosuccinic acid (DMSA) scan (which was performed at a median of 27 days), ultrasonography, micturating cysto-urethrography and indirect voiding radionuclide cystography using 99mTc DTPA. Follow-up DMSA scan was carried out after 6 months. Twenty-one of 102 of initial DMSA studies showed diminished uptake of radionuclide and 12 showed cortical scarring. Twenty-nine patients had significant vesicoureteral reflux (VUR). The finding of diminished uptake on the initial scan was significantly associated with fever, systemic upset, length of symptoms and a peripheral blood leucocytosis, (p less than 0.05). In addition the finding was associated with fever and loin pain in the older child. Both diminished uptake and scarring were more common in refluxing kidney units. We propose that, in children with UTI, diminished uptake on early DMSA scan localises infection in the renal parenchyma.

A 32-yr-old man presented with acute renal failure preceded by a viral-like disease with high fever, bilateral loin pain, nausea, headache and slight thrombocytopenia. Renal biopsy revealed only minor tubulointerstitial abnormalities. Renal function completely normalised within 10 days after hospitalisation. The diagnosis of acute Hantavirus nephropathy was proved by serological examinations.

Thin-membrane nephropathy recently has been described as a cause of glomerular haematuria. The prognosis of the condition is unclear but it generally is considered to be benign. In a series of 92 patients with glomerular haematuria, thin-membrane nephropathy was found to be a common cause, occurring in 26 (28%) patients. Sixteen patients were women. The mean age was 42 years. Four patients had a family history of renal disease or haematuria and no patient was deaf. Haematuria had been present from six days to 30 years. Loin pain occurred in 31% of patients. Hypertension was not a feature and mild renal impairment was present in one case only, while a further three cases showed proteinuria at a level of greater than 500 mg of protein per day. Glomerular basement membranes in patients with thin-membrane nephropathy gave a mean (+/- standard deviation) width of 319 + 37 nm which was significantly (P less than 0.002) less than the control value of 394 +/- 61 nm. On the basis of clinical features and serological parameters, thin-membrane nephropathy could not be separated from other renal causes of haematuria but required careful electronmicroscopic examination of renal biopsy material to establish the diagnosis. Limited follow-up has confirmed the good prognosis of the condition.

Two cases of renal segmental infarction and 1 case of renal patchy ischemia demonstrated by magnetic resonance imaging (MRI) are reported. MRI of renal infarction in two renal grafts following surgical ligation revealed an area of noncorticomedullary differentiation and an area with a low signal intensity. Renal ischemia in 1 patient with acute renal dysfunction with severe loin pain and patchy renal vasoconstriction was visualized as an ill-defined focus of low signal intensity in the renal cortex, indicating a long T1 relaxation time. Delayed wedge-shaped contrast enhancement was demonstrated on CT scan in the same area. The common finding in renal infarction and ischemia in our cases was the area of low signal intensity on MRI.

Afferent arteriolar C3 deposition was the sole histological abnormality in 79 and the major histological abnormality in an additional 39 of 959 renal biopsies performed over a 10-year period. Of these 79 patients, hematuria was the presenting symptom in 90%, with coincident loin pain in 49%. Urine microscopy of asymptomatic first-degree relatives revealed hematuria in 44% of children and siblings and 54% of parents, suggesting autosomal dominant inheritance. Arteriolar C3 deposition was confirmed by biopsy in four asymptomatic relatives with hematuria. Generalized thinning of glomerular basement membrane (less than 200 nm) was observed in five patients and focal thinning was observed in six patients with coincident afferent arteriolar C3 deposition. Seven other patients were identified as having generalized thinning of glomerular basement membrane in the absence of afferent arteriolar C3 deposition. Renal function was stable and similar in all groups studied over 37.9 +/- 23.7 months. No difference in clinical presentation or urinary abnormalities was evident between the groups. No arteriolar C3 deposition was evident in eight autopsy specimens with no known renal disease. It was concluded that afferent arteriolar C3 deposition is a marker of a distinct hereditary pathological entity, with differentiation from thin basement membrane disease not possible on clinical grounds. The medium- and long-term prognoses with respect to renal function are excellent.

Recent advance of radiographic technique makes antemortem diagnosis of renal vein thrombosis (RVT) possible. However the incidence of RVT in patients with nephrotic syndrome(NS) is still not known. This study was designed to investigate the incidence, clinical presentation and radiological features of RVT in NS patients in China. A prospective study including clinical, and pathological examination as well as renal venogram was carried out in all our hospitalized NS patients except those having contradiction for renal venogram. RVT was found in 23 of the 54 cases (42%) and there was obstruction in 34 renal vein branches. RVT was more common in left (19) than right side (15), in upper (19) than middle and lower branches (10). It is interesting that in our group not only membranous but also minimal change as well as mesangium proliferative glomerulonephritis had high incidence of RVT (47%, 45% and 36% respectively) Only 6 cases (26%) had a typical acute presentation with severe loin pain, significant increase of urinary protein, enlargement of involved kidney. Occasionally fever, deterioration of renal function and sterile urinary white cells were also present. The remaining patients (74%) had latent onset of RVT which could hardly be identified in the clinical course of the underlying NS. For the high incidence and atypical clinical course of RVT shown in our study, it is recommended that due attention should be paid of this complication during management of NS and interpretation of therapeutic response.

Most forms of therapy for the loin-pain/haematuria syndrome are unsuccessful, though nerve-block procedures and renal denervation sometimes provide temporary relief. Three young patients, with pain so severe that they were dependent on narcotics, were treated for this syndrome. All three had been repeatedly admitted to hospital. Loin pain was unilateral in two patients and predominantly so in the third. Renal function, excretion urography, and angiography were normal, but renal biopsy specimens showed deposition of the third component of complement in the renal arterioles. All were treated with renal autotransplantation; the kidney causing pain (or the one causing the most pain) was completely excised and reimplanted in the iliac fossa. Two patients had complete relief of pain and the third almost complete relief, despite recurrence of haematuria in all three. It is too early to determine whether this major procedure is justified in the treatment of the loin-pain/haematuria syndrome, but the early results are encouraging.
