1) This rare case of unilateral bifid ureter can not be found in the literature. 2) It has been located in the left mid ureter and O shaped in its form nominated O shaped bifid ureter by author 3) It is diagnosed on the basis of the IVP and R.G.P..

Pyelocaliceal diverticulum is a well recognized uncommon entity, usually noted incidentally on excretory urography by lack of clinical symptoms, About 500 cases had been reported with similar entity till 1975. We report 6 cases of stone-containing pyelocaliceal diverticula and additional one case and the literature has been reviewed briefly.

Drip infusion pyelography by Schencker technique was carried out on total of 20 cases, 7 normal and 13 abnormal. Of 13 abnormal cases, definite diagnosis could be obtained in 1 cases in which conventional urography had not been helpful in establishment of diagnosis, and significant information could be obtained in 6 cases. This is the first report on drip infusion pyelography in this country and no complication was observed during the examination. Drip infusion pyelography was found valuable in cases with the following problems; 1) When valuable information can not be obtained through the conventional urography. 2) When renal function is poor. 3) When delineation of anatomical details is desirable. 4) When retrograde pyelography is contraindicated. Drip infusion pyelography is a safe, new and widely accepted diagnostic procedure in urographic study.

We report one case in which delayed enhanced computerized tomography (1.5 hr. later) contributed in detecting a dysplastic kidney with a single vaginal ectopic ureter that had been nonfunctioning on excretory urography and had not been detected by other diagnostic methods.

To elucidate whether dismembered pyeloplasty improves renal function, the authors studied 37 patients with ureteropelvic junction obstruction. Changes in various renal parameters pre-and postoperatively by 99mTc-DTPA diuretic renal scintigraphy(DTPA scan) and intravenous urography were evaluated. Subjects included 24 pediatric(mean age 9.7 years) and 13 adult(mean age 33 years) patients. Postoperative split renal function was improved in 79 % (l9/24) of pediatric patients and in 69%(9/13) of adult ones. While, the excretory slope was improved in 71%(17/24) of pediatric patients and in 77%( 10/13) of adult ones. Hydronephrosis on intravenous urogram was improved in 58% (14/24) and 54% (7/13), respectively between pediatric and adult patients. There was no statistically significant differences of improvement in split renal function and renographic washout curve between pediatric and adult patients. In summary, renal function was improved by dismembered pyeloplasty in both pediatric and adult patients.

Developing the instruments in urological field, the urinary tract stones may be manipulated more easily and lesser invasively recently. The percutaneous nephrolithotripsy is one of the most widely using technique for the renal stone. But, the major portion of the failure through the manipulation of percutaneous nephrolithotripsy is the access to the correct, wanted calyx by puncture. So, we observed the 27 normal right kidneys and 26 left kidneys by abdominal computer tomogram scanning and excretory urography for the Korean caliceal anatomy. The following results were obtained 1. The average values of posterior renal rotation from the coronal plane of body were 31.0 degrees +/- 4.4 degrees in the right kidneys 32.4 degrees +/- 3.2 degrees in the left kidneys. 2. The average values of anterior and posterior caliceal angle were 58.8 degrees +/- 7.6 degrees and 20.7 degrees +/- 5.8 degrees in the right kidneys; 38.3 degrees +/- 6.2 degrees and 43.0 degrees +/- 5.2 degrees in the left kidneys. 3. The major type of classical system was Brodel type (74.l%) in the right kidney; Hodson type (53.8%) in the left kidney. 4. The anterior calyx is more laterally placed about 8l.8% in the excretory urography.

During the period from January 1978 to December 1980, 46 patients who were taken RGP were analyzed and observed as follows. 1) RGP was performed 46 patients who were not defined exactly on IVP. 2) Undefined findings on IVP that was performed RGP classified into four group as follows. Group I : Abnormal changes or poor visualization of calyx, pelvis and ureter; 17 (32.7%) Group II : Hydronephrosis; 12 cases (23.1%) Group III : Delayed visualization; 9 cases (17.3%) Group IV : Non-visualization; 14 cases (26.9%) 3) Of the 46 patients (52 kidneys), 35 patients (41 kidneys) were defined with RGP and remained 11 patients (11 kidneys) had been required other special urologic studies for further evaluation.
