The Effect of Age, Prostate volume and Total PSA on Percent free PSA in Men with Benign Prostatic Disease / 대한비뇨기과학회지

PURPOSE: We assessed the influence of age and prostate volume on the serum total PSA and percent free PSA level, and total PSA on the percent free PSA level in men with benign prostatic disease except clinically detectable prostatic cancer. MATERIALS AND METHODS: Sera were obtained from 250 men with total PSA level of 0 to 20 ng/ml who were clinically negative for cancer. Total and free PSA levels were measured using ELSA-PSA2 and FPSA-RIACT immunoradiometry assay. Prostate volume was determined by transrectal ultrasound. RESULTS: Age and prostate volume correlated significantly with Total PSA levels (r=0.204 and 0.482, p<0.05) and free PSA levels (r=0.246 and 0.539, p<0.05) but not with percent free PSA(r=0.057 and -0.039, p=0.188 and 0.541). Total PSA levels correlated significantly with free PSA(r=0.853, p<0.05) and percent free PSA(r=-0.398, p<0.05). CONCLUSIONS: Among men with total PSA levels of 0 to 20 ng/ml and do not have clinically detectable prostatic cancer, total PSA and free PSA increases with increasing age and prostate volume. And percent free PSA decreases with increasing total PSA but it was not influenced by age and prostate volume.

Clinical Observations in Penlie or Urethral Injuries during Penile Eection / 대한남성과학회지

PURPOSE: Penile or urethral fractures are a rare urologic emergency that occur only during erection as a result of direct blunt trauma that vends the organ in an unphysiologic manner. We present our experiences in the management of 18 patients with penile or urethral injury sustained juring erection. PATIENTS AND METHODS: Between January 1991 and June 1998, 18 patients were hospitalized for penile or urethral injury, rupture often as a result of sexual intercourse. They were managed by early surgical repair (N=10) or conservatively (N=8). Cavernosography was performed in 10 patients and urethrography in 2 patients. The patients ages at presentation ranged from 24 years to 54 years, with a mean of 35.9 years. The mean follow-up was 40.9 months (range 4 to 80). RESULTS: Cavernosography showed extravasation of contrast medium in 4 patients. Surgical exploration in 10 patients revealed rupture of the tunica albuginea. Postoperative wound infection was observed in two patients but healed without late complication. All patients regained erectile potency, although penile curvature during erection that did not affect sexual activity was observed particularly in one patient who had received conservative treatment. CONCLUSIONS: Surgical exploration is advocated particularly in the case of severe or expanding penile hematoma, severe penile deformity and rupture of turnica albuginea. Conservative treatment can be chosen only when the corporeal bodies are intact and there is neither signs of bleeding nor severe hematoma in the penis.

The Role of Computerized Tomography in the Diagnosis of Bladder Rapture

BACKGROUND: Computerized topography(CT) is the method of choice for establishing patients with abdominal and/or pelvic trauma. However, the sensitivity of CT far detecting bladder rupture has been questioned. We investigated the roles of CT as the initial evaluation of abdominal and pelvic trauma in diagnosis of bladder rupture. METHODS: We reviewed the medical records and radiographs of 53 patients with bladder rupture for last 5 year. And among them, all radiographs of 30 patients who underwent both CT and retrograde cystography were evaluated independently by two urologists who had no knowledge of the patients' final diagnosis. RESULTS: Among 30 patients, all of patients were correctly diagnosed by retrograde cystography, but the CT diagnosis was correct in only 23 patients(76.7%), who were 17 patients(85.0%) with intraperitoneal rupture and 6 patients(60%) with extraperitoneal rupture. And of the 7 patients who were negative by the CT, all showed the sign of inadequate bladder distension. CONCLUSION: We suggest that CT, if properly performed with adequate bladder filling, is as sensitive for detection of bladder injuries as conventional cystography. Especially, in trauma patients with hematuria and suspected other organ injury, CT-cystography with retrograde filing may be as accurate as conventional cystography and obviate the need for an additional plain film cystography,

A Case of Ganglioneuroma in the Pelvic Cavity / 대한비뇨기과학회지

We present a case of ganglioneuroma arsing from the sympathetic ganglia in the pelvic cavity.

A Case of Renal revascularization using Aortorenal Saphenous Vein Bypass Grafting in Renovascular Hypertension / 대한비뇨기과학회지

Renovascular hypertension is the leading cause of surgically curable arterial hypertension. With the marked advancement in the technique of vascular surgery, renal revascularization is preferred to nephrectomy. It is used for the recovery of impaired function or the prevention of renal failure and the control of hypertension. We report a case of renovascular hypertension with the nonfunction of the left kidney due to complete renal artery obstruction, treated successfully with an aortorenal bypass graft.
