“…Postoperatively, 14 of 28 patients in our study exhibited improved drainage function. This is a rather low figure but corresponds well with the data presented by Davies, Jones and Croft (1969) who demonstrated an improvement in pelvic emptying in 10 out of 20 operated kidneys. The improvement rate varies considerably in different studies however.…”

The glomerular filtration rate and pelvic drainage function were reinvestigated after 3-5 years in 50 patients with hydronephrosis secondary to functional obstruction in the pelvic-ureteric junction. Pyeloplasty by the Anderson-Hynes' technique had been performed in 28 kidneys, while 12 patients were not operated upon and 10 had had a nephrectomy. The glomerular filtration rate was determined with the clearance technique and isotope renography. 16 out of 28 kidneys subjected to pyeloplasty and 11/12 non-operated kidneys had a normal renal parenchymal function at the first investigation in spite of severely disturbed drainage function. In the non-operated series the renal parenchymal function was unchanged in 11 patients. Deterioration was observed in 1 kidney, probably because of chronic pyelonephritis. Uncomplicated cases of pelvic-ureteric junction obstruction should not be operated upon unless necessitated by symptoms. A yearly control programme including a renal function test and plain films of the upper urinary tract is recommended for these patients.

“…In fact, when isotope renography was introduced in clinical medicine in 1956 it was the possibility the technique provided of evaluating the urinary excretion from the pelvis which was especially appreciated. This function has been especially studied by Bergstrom (1971) in obstetric patients.…”
