BACKGROUND: Aim of this study was a retrospective analysis of the renal biopsies performed in our Division. METHODS: Since January 1, 1996 to September 30, 1999 289 biopsies were performed on native kidneys, 90 patients were older than 65. RESULTS: The most frequent nephropathy was IgA glomerulonephritis (IgAGN) (28%), followed by membranous glomerulonephritis (MGN) (11%). In patients older than 65, the most frequent was MGN (20%), followed by IgAGN (12.2%). The total complications were 84 (29.1%) (hematomas >3 cm 1%; blood transfusion: 1.4%). Complications were not related to age, blood pressure, renal function, clinical presentation, number of shots. In 217 patients, the results obtained with two different modalities were compared: manual system (needle size=15 gauge) and automatic system (18 gauge). No statistically significant differences were found as regards the number of shots for single biopsy, number of glomeruli and major complications (1.6% vs 1.3%), while minor complications were more frequent in the second group. CONCLUSIONS: In conclusion, the number of renal biopsies performed in our Division has been increasing year after year. This trend can be partially explained by our wider indications to renal biopsy in elderly population (the data related to resident population showed the greatest prevalence of biopsies in patients 70 to 79 years old). Renal biopsy actually represents a safe examination even in elderly patients. From a technical point of view, on the basis of personal experience, 18 gauge acecut automatic needles seem to be preferred to other kind of devices.

Two hundred and one patients had biopsies of their native kidneys with ultrasound-guided needle technique. They were evaluated on the second post-biopsy day with colour-coded Doppler sonography. Ten patients out of these 201 were found to have an arteriovenous fistula, which remained asymptomatic for the whole follow-up period (follow-ups ranged from 2 to 31 months). Four of these 10 patients developed a perirenal haematoma as well and five macroscopic haematuria. Our study shows that the systematic use of colour-coded Doppler sonography after renal biopsy facilitates diagnosis of arteriovenous renal fistula.

A case of lipoma of the colon with a clinical picture of intestinal occlusion due to colo-colic invagination is reported. The invagination diagnosis was arrived at preoperatively by opaque clysis and echography. Surgical treatment consisted of segmentary resection owing to trouble in the affected ansa.

Chronic constipation and defecation disorders are a very common disease, but the diagnosis is often unsatisfactory and therefore therapy is mostly inadequate. The purpose of this paper is to demonstrate the contribution of radiological procedures and mainly of the defecography, in improving and determining the diagnosis itself. Many normal and pathological cases are reviewed, described and demonstrated by radiological patterns. Finally, a correct protocol of different procedures, radiological and not, for morphological and functional study of large bowel and pelvis floor is stressed.

Renal artery stenosis is a frequent complication of kidney transplantation (10%). Percutaneous transluminal angioplasty (PTA) has recently been proposed as a potential therapeutic procedure. Twelve transplant patients with arterial stenosis underwent PTA. The procedure was successful in 10 cases (83.3%). Restenosis occurred in 2 patients (16.7%); both of them underwent PTA successfully. No complications occurred. A considerable improvement in glomerular filtration rate and a reduction in high blood pressure were observed in all patients after successful PTA. The authors believe PTA to be the therapy of choice in the treatment of arterial stenoses in kidney transplant patients.
