A Clinical Observation on Retrograde Pyelography / 대한비뇨기과학회지

Authors reviewed 110 cases of retrograde pyelography which performed in the Dept. of Urology, Kyung Hee University Hospital during the period from January 1977 to December 1980. And the results were as follows. 1. Indication was 34 cases (31%) of nonvisualizing kidney, 31 cases (28%) of obstructive lesion, 21 cases (19%), of inadequate filling in pelviocalyceal system, 7 cases (6.5%) of impaired renal function. 6 cases (5.5%) of upper tract abnormality, l cases (0.9%) of allergy to contrast media and other 10 cases. 2. On the nonvisualizing kidney, hydronephrosis (23.5%) was most common and normal (20.5%), ureter stone (20.5%) in order. 3. For assessment of obstructive lesion, UPJ stricture (39%) was most common and ureter stone (32%), normal (16%), ureter tumor, UVJ stricture in order. 4. Inadequate filling on excretory urogram revealed normal (24%), renal tumor (19%), renal tuberculosis (9.5%) and chronic pyelonephritis scar (9.5%) etc. 5. The patients who had poor renal function or poor general condition and upper tract abnormality were well defined with retrograde pyelography and available for diagnosis and treatment. 6. Complication were seen in 2 cases (1.8%). One was acute pyelonephritis and the other was pyonephrosis.

Clinical Observation on Renal Angiography / 대한비뇨기과학회지

Renal angiography is now one of invaluable adjuncts to urologic disease with computed tomography and ultrasonography. Authors observed in 50 cases of renal angiography which performed in the Department of Urology, Kyung Hee University Hospital during the period from September. 1977 to August 1980. In detecting and defining both the presence and extent of renal diseases such as tumor, cyst, injury and vascular disorder, renal angiography is highly reliable and accurate.

Computed Tomography in Urology / 대한비뇨기과학회지

Recently, the new modality of computed tomography has been demonstrated to define with remarkable clarity not only the normal anatomy of the urologic organs but also disease processes in the retroperitoneum and pelvic cavity We have performed 36 cases of C-T scan in urologic field. The results are as following. 1. C-T scan is an easily accomplished diagnostic method which provides highly accurate and clinically useful information about retroperitoneal tumor 2. C-T scan is useful diagnostic method for change of bladder wall or intravesical status on bladder tumor. 3. C-T scan is less helpful in detecting lymph node metastases of bladder tumor 4. C-T scan is valuable in evaluating the response of therapy and recurrence of the tumor.
