“…It has previously been shown that there is a significant correlation between renal parenchymal area determined from urography and GFR in the same renal disorder (1,7,16). The results were confirmed in the present investigation.…”

A comparison of the relationship that might exist between ultrasonographically calculated renal parenchymal volume and renal parenchymal area assessed from urography and also between renal parenchymal volume and kidney function was conducted in a series of 26 children with recurrent urinary tract infection or asymptomatic bacteriuria. Glomerular filtration rate (GFR) was determined by the clearance of inulin, renal parenchymal area was measured from urography and renal parenchymal volume was calculated from sequential longitudinal scans of the kidney using an automated water-delay ultrasonographic equipment (Octoson). High correlation was found between 1) renal parenchymal volume and GFR, 2) renal parenchymal volume and renal parenchymal area and 3) renal parenchymal area and GFR. Octoson ultrasonographic determination of renal parenchymal volume is a reliable method to evaluate glomerular filtration rate and renal parenchymal area in children with recurrent urinary tract infections and asymptomatic bacteriuria.

“…During the last few years length (12,14) and renal volume (2,6,14) have been determined by ultrasonography. Renal parenchymal area measured on the urogram has been shown to be directly related to glomerular filtration rate (1,7,16) in some childhood renal disorders.…”

“…They studied the inulin clearanee of each kidney by catheterizing the bladder and obtaining urine separately from each kidney by external compression of the contralateral ureter. Tamminen et al (17) also found a correlation bctween kidney parenchymal area and renal function in patients with recurrent urinary tract infection with reflux, using 99mTc-DTPA-clearanee as a crite-Vihma etat non of renal function. A good correlation between kidney parenchymal area and kidney function was demonstrated in patients with hydronephrosis, recurrent pyelonephritis or sin-,le kidney by Haugstvedt et al (5), who used a combination of 25I-Hippuran renography and 51 Cr-EDTA-clearance for calculation ofindividual kidney function.…”

In 33 patients with pelviureteric obstruction the renal parenchymal area was measured from excretory urography films and split renal function determined with computerized 99mTc-DTPA-renography. All patients had pelviureteroplasty performed during childhood. For this study, excretory urographs and DTPA-renographs performed in 7 patients preoperatively and in all the 33 patients 10 months to 15 years postoperatively, were analyzed. The parenchymal area of both hydronephrotic and healthy contralateral kidneys showed good correlation with split DTPA clearance. The percentile parenchymal area of the hydronephrotic kidneys also had good correlation to their percentile split DTPA-clearance. The planimetric measurement of kidney parenchymal area and DTPA renography are useful alternative methods when evaluating split renal function, severity of hydronephrosis and the result of pelviureteroplasty.

“…The split isotope uptake was estimated from the ratio of the slopes of the linear uptake phase of the renogram. The washout pattern was given routinely but not the half time [10,11]. Mercaptoacetyl triglycine (MAG-3) was used as an alternative in the initial examinations in 3 patients.…”

Outcome of patients with antenatally detected pelviureteric junction obstruction

We investigated the outcome of patients with antenatally detected pelviureteric junction (PUJ) obstruction treated either conservatively or surgically. The series comprised 68 such patients, 54 with unilateral obstruction. Of the unilateral cases, 22 units were treated conservatively, 21 underwent early and 11 late surgery. Of the bilateral cases, 18 units were treated conservatively, 9 underwent early pyeloplasty, whereas 1 underwent later surgery. Among the conservatively treated unilateral cases, none of the patients' good renal function deteriorated during follow-up. In the group with early surgery, the primary good function remained unchanged in all. In some patients, moderate function improved after early pyeloplasty, but in patients with poor function no improvement occurred. Of patients who underwent late pyeloplasty, primary good renal function remained unchanged in all except 1, although it had deteriorated to moderate function in some before surgery. In all except 1 patient with bilateral obstruction treated conservatively, both the grade of hydronephrosis and split function remained unchanged. In most patients the outcome of antenatally detected unilateral PUJ obstruction with initially good renal function, whether treated conservatively or surgically, seems favorable. Some patients with moderate function might benefit from pyeloplasty. In kidneys with poor function, recovery may be minimal despite pyeloplasty.
