Clinical Observation of Antegrade Pyelography / 대한비뇨기과학회지

Clinical observation was made on 30 patients of obstructive uropathy who were performed antegrade pyelography in Department of Urology, Catholic Medical College, during the period from 1971 to 1976. It revealed antegrade pyelography is the most useful diagnostic procedure and accurate to demonstrate the morphology, site and cause of the obstructive lesion, and it leads to adequate procedure of operation. The results were as follows: 1. Non-visualized kidney (10 cases) and hydronephrotic kidney (23 cases) on intravenous pyelography were definitely diagnosed by antegrade pyelography. Non-visualized kidney (10 cases) on intravenous pyelography was distinctly diagnosed as hydronephrosis (7 cases) and hydronephrosis combined with caliceal destruction (3 cases) , and hydronephrotic kidney (23 cases) on intravenous pyelography was diagnosed as hydronephrosis (16 cases) and hydronephrosis associated with caliceal destruction (7 cases) 2. The main cause of obstructive uropathy revealed renal tuberculosis (15 cases), congenital ureteropelvic junction stricture (3 cases) and ureteral stone (3 cases) etc. 3. 32 cases of all 33 cases were noted ureteral obstruction. In these 32 cases, the sites of ureteral obstruction were lower 1/3 of the ureter (20 cases), upper 1/3 of the ureter (8 cases) and multiple ureteral obstruction (4 cases). 4. With definite diagnosis by antegrade pyelography, adequate operation could be performed; nephrectomy (11 cases), ureteral re-implantation (7 cases), nephrostomy (6 cases), cutaneous ureterostomy (5 cases) and pyeloplasty (2 cases).

Clinical Observation on Surgical Ureteral Injuries / 대한비뇨기과학회지

The author experienced 30 cases(22 patiente) of surgical ureteral injuries during the 9 years period from August 1968 to July 1977 at the Department of Urology, St. Mary's Hospital. Catholic Medical College. The results were as follows : 1. The main etiology of surgical ureteral injury were gynecologic pelvic surgery(10 patients). ureteral tailoring and re-implantation(3 patients), ureterolithotomy(2 patients) and Ureteroileocystoplasty(2 patients). 2. The main symptoms of ureteral injuries revealed urine leakage(13 patients), flank pain(6 patients), fever(3 patients), nausea & vomiting(3 patients) and abdominal pain(3 patients). 3. Ureteral injury was diagnosed by intravenous pyelography, retrograde ureteral catheterization and indigocarmine test. 4. Reconstruction of the ureteral injury were performed by the method of ureteroneocystostomy (7 cases), Boari operation(4 cases), ureteroureterostomy(2 cases), ureterolysis and ureteral catheter drainage(2 cases) and simple suture(3 cases). The results, were best in ureteroneocystostomy and Boari operation. 5. Ureteral stent catheter were placed in 12 patients and the average duration of catheterization was 11 days.
