Background: Antenatal hydronephrosis(ANH) has now become a frequent diagnosis with the increasing use of antenatal ultrasonography. Objective of present study was to evaluate and follow up infants with antenatally detected hydronephrosis and to determine whether there is significant correlation between anteroposterior renal pelvic diameter detected in antenatal USG and urinary tract anomalies detected postnatally.Methods: After obtaining an informed consent, all neonates with antenatal ultrasound showing hydronephrosis (n=80) were enrolled in the study. Postnatal ultrasound was done at 3 days ,1 month and 6 months of postnatal life. Atleast 6 months followup was done to look for spontaneous resolution or other significant pathology. Micturating cystourethrography/radionuclide scan done in selected cases.Results: Out of 80 cases ,43 had mild,24 had moderate and 13 had severe degrees of hydronephrosis.31 of them (9 mild,10 moderate and 12 with severe hydronephrosis) had postnatal anomaly detected.14 of them (1 mild, 4 moderate and 9 with severe hydronephrosis) underwent surgery. As the grade of antenatal hydronephrosis increases from mild, moderate to severe, the relative risk of postnatal anomaly and requirement of surgical intervention also increased (p value<0.0001).Conclusions: Antenatal hydronephrosis may be associated with significant postnatal urinary tract anomaly with risk quantified by the measurement of anteroposterior renal pelvic diameter(APPD).

When used as a screening procedure, ultrasound examination of the fetal urinary tract seldom leads to beneficial interventions. There is also a cost in terms of parental anxiety and unnecessary investigation and treatment. A formal screening programme would therefore be unjustified. However, screening of women for obstetric purposes will continue to reveal fetal abnormalities, and a strategy for dealing with these is needed. Antenatal treatments remain experimental; for most of the common conditions postnatal treatment has no urgency; and, in cases of minor abnormality detected by ultrasound, the best course may be to do nothing.

Reliable Indication

INFECTIONS of the urinary tract are second only to infections of the respiratory tract in frequency and, therefore, represent a very common pediatric problem. In most instances the infection involves the kidney substance (pyelonephritis). In recurrent or chronic infections, usually superimposed on a congenital anatomic defect, functional damage often results. Because of the serious consequences of untreated urinary infection, early diagnosis is imperative, particularly so where there is an associated urinary tract anomaly and where infection tends to persist. Localizing clinical signs of infection in the urinary tract are too commonly absent to be relied on for a diagnosis, and pyuria, the usual indication of infection in the urinary tract, may be absent in the presence of infection. To date, the most reliable indication of infection in the urinary tract is obtained by finding bacteria in the urine in significant numbers.

The aim of this study is to investigate the incidence of urolithiasis in kidney transplant recipients and evaluate the potential of using minimally invasive treatment techniques for these patients. Patients underwent ultrasound examination of the transplanted kidney and urinary tract during regular screening. When a concretion was found, multispiral computed tomography was additionally performed to clarify the size, location, and X-ray density of the concretion. We did not perform contrast enhancement to avoid acute kidney damage to the graft. Additionally, all patients underwent a comprehensive examination with the evaluation of clinical tests of blood, urine, biochemical blood analysis (including creatinine, urea, phosphorus, magnesium, calcium, parathyroid hormone). The patients with a stone of up to 5 mm in diameter and X-ray density below 1000 HU were prescribed dynamic follow-up and litholytic therapy. Contact ureterolithotripsy was performed in the patients with stones of more than 6 mm in diameter. We studied the mineral composition of stones after lithotripsy using infrared spectroscopy. According to the results obtained, the detection rate of urolithiasis in kidney transplant recipients was 7.8%. The patients with graft and urinary tract stones showed a significant increase in the level of parathyroid hormone and blood calcium, leukocyturia of varying severity compared to the patients without urolithiasis. After performing contact ureterolithotripsy, the "stone free" state was achieved in all patients and confirmed by a control ultrasound examination on the fifth day after lithotripsy. Infrared spectroscopy of the removed stone fragments demonstrated their mixed mineral composition, the dominant component of which was calcium phosphate. The data obtained point out the possible pathogenetic factors of the formation of urinary stones in kidney transplant recipients are hyperparathyroidism and the resulting hypocalcaemia, as well as urinary tract infection. Contact lithotripsy should be considered as the method of first choice in this group of patients.
