[Chronic renal failure secondary to vesicoureteral reflux: is the prevention possible?].

Vesicoureteral reflux (VUR) is the commonest cause of end-stage renal failure reported by the ITALKID (Italian Register of Chronic Renal Failure) (CRF) in children (0-15 years). Herein we report 131 children (53 M and 78 F) with a diagnosis of VUR made in our Centre between 1987 and 1994. Diagnosis was made in 69% of cases (85/131) during the 1st year of life and in 31% of cases (47/131) afterwards. VUR was demonstrated following a prenatal ultrasonography suspicion in 24/131 and after symptoms such as urinary tract infection (94/131) and poor growth (6/131). 75/131 of patients were treated conservatively (continuous chemoprophylaxis) while 56/131 underwent an antireflux surgery. CRF was found in 14% (19/131) of cases even though the diagnosis of VUR was performed in most of the cases (79%) during the 1st year of life. In conclusion prenatal ultrasonography has a low sensibility in the diagnosis of VUR. In addition, an early diagnosis made during the 1st year of life do not prevent CRF. The study was carried out in a Centre where patients with urological problems are referred from a large part of Northern East of Italy and this may explain the high prevalence of CRF and of children receiving a surgical treatment.

The Italian Registry of Pediatric Chronic Peritoneal Dialysis: a ten-year experience with chronic peritoneal dialysis catheters.

OBJECTIVE: To analyze the data from 347 peritoneal catheters implanted in 249 pediatric patients aged < or = 15 years at start of chronic peritoneal dialysis (CPD). DESIGN: Restrospective study of the data collected between 1986 and 1995, in 20 dialysis centers, from the Italian Registry of Pediatric Chronic Peritoneal Dialysis. Data collection for each pediatric catheter included: catheter type, site and technique of insertion, complications, duration, and reason for removal or replacement. RESULTS: Fifty catheters were inserted in patients under 2 years of age, 50 in patients aged 2 - 5 years and 247 in patients over 5 years of age. Catheter types included 307 (88.5%) Tenckhoff (286 double cuff, 21 single cuff) and 40 (11.5%), double-cuff, Valli-type catheters. All catheters were surgically implanted and omentectomy was performed in 83.5% of cases; the entry-site was in the midline in 136 cases (39.2%) and paramedian in 211 (60.8%). During 6076 CPD months we observed 274 catheter-related complications: 182 catheter infections (exit-site and/or tunnel infection), 23 leakages, 19 obstructions, 19 cuff-extrusions, 14 dislocations, 6 hemoperitoneum, 10 other (incidence of one complication every 21.8 dialysis-months). A significant reduction of catheter-related complications occurred in the last five years, compared with the first 5 years. One hundred and six catheters were removed due to catheter-related causes: infection (83 cases), obstruction (11), dislocation (4), outer-cuff extrusion (3), leakage (2), bowel incarceration (2), and bowel infarction (1). Catheter survival was 72.2% at 12 months, 52.3% at 24 months, 32.8% at 36 months, and 25.7% at 48 months. Significantly lower catheter survival was found in younger children (0 - 2 years) compared with two other age groups (2 - 5 years, and > 5 years). No significant correlation was found between catheter survival and catheter entry-site (midline vs paramedian). CONCLUSIONS: Catheter-related infections were confirmed to be the most common complication and most frequent cause of peritoneal catheter removal. In addition, catheter survival rate was worse in younger children, indicating that more effort should be made to improve peritoneal catheter survival particularly in this age group.
