Effects of digital rectal examination and transurethral resection of the prostate on serum prostate Specific antigen and acid phosphatase levels / 대한비뇨기과학회지

To identify the effect of digital rectal examination (DRE) and transurethral resection of the prostate (TURP) on the serum prostate specific antigen (PSA), serum acid phosphatase and prostatic acid phosphatase (SAP/PAP) concentration a clinical trial involving 73 patients was conducted. Of the patients 65 (89 %) had benign prostatic hyperplasia (BPH) and 8(11 %) had prostate cancer (stage A1, A2). We detected no clinically significant difference between serum PSA and prostate acid phosphatase (PAP) levels obtained immediately before, at 5 to 30 minutes after rectal examination and post-TURP in 73 men. Patients were divided into four groups based on their initial serum PSA levels. The three groups with the initial PSA values (0.1 through 4 ng/ml and greater than 10 ng/ml) were found to have statistically insignificant changes in the serum PSA levels after DRE and post-TURP. The group with initial PSA levels of 4.1 through 10 ng/ml had statistically increases in serum PSA values after TURP, but the alterations in serum PSA levels in the group with the inter- mediated PSA value was not clinically important. We conclude that digital rectal examination (DRE) and transurethral resection of the prostate (TURP) have no clinically important effects on serum PSA in BPH and occult prostatic cancer (stage A1, A2) patients.

Comparison of extracorporeal shock wave lithotripsy and ureteroscopy for management of lower ureteral stones / 대한비뇨기과학회지

115 patients with lower ureteral stone for which intervention was considered have been treated by ureteroscopy (URS) or in situ extracorporeal shock wave lithotripsy (ESWL). Of 57 patients treated by URS, successful evacuation of major part of the stone was achieved in 73.7% but 1 patient was required surgery for serious complications. In the ESWL group of 58 patients. stone free rate was recorded in 98.3% and there were no significant complications. We conclude that ESWL should be the primary method of intervention in patients with lower ureteral stone, in view of therapeutic effectiveness such as hospital stay, anesthetic risk, stone free rate and complications.

Obstruction of the lower ureter by obliterated umbilical artyery: report of a case / 대한비뇨기과학회지

The congenital hydronephrosis due to lower ureteral obstruction is not common. In case of congenital obstruction of the lower ureter. the aberrant blood vessels. obliterated vessels or fibrous tissue bands can be the cause of it infrequently. We observed a case of lower ureteral congenital obstruction by obliterated umbilical artery in a 12-yr-old boy. A retrograde pyelogram showed left hydroureteronephrosis with evidence of partial obstruction near the ureterovesical junction. At operation a obliterated left umbilical artery was found compressing the ureter 2 cm. proximal to the ureterovesical junction.
