Prostatitis and benign prostatic hyperplasia (BPH) are common prostatic diseases. Furthermore, the incidence of prostate cancer has recently shown a rapid increase, even in Korea. Pain caused by prostatitis may induce sexual dysfunction, including erectile dysfunction and ejaculatory disturbance. And BPH itself, or treatments for BPH, may affect sexual function. In addition, with increased detection of localized prostate cancer, surgical treatments and radiation therapy have also increased, and the treatments may cause sexual dysfunction. Aging is also an important factor in the deterioration of the quality of life of men. Deterioration of quality of life caused by prostate diseases may be affected not only by the prostate diseases themselves but also by the sexual dysfunction caused by the prostate diseases secondarily. Thus, consideration of these points at the time of treatment of prostate disease is required. Therapies suitable to each condition should be selected with an understanding of the close association of prostate diseases and associated sexual dysfunction with the quality of life of males.

Screening and detecting sexually transmitted diseases (STDs) is a form of secondary prevention, which interrupts further transmission as well as progression of the infection and its sequelae. Unfortunately, primary prevention, by means of education and taking safe sex partners, has not been enough to significantly curb the prevalence and high cost of STDs. Bacterial STDs are decreasing in their prevalence whereas the prevalence of viral STDs has increased significantly in recent years. The differential diagnosis for genital ulcers, urethritis, and genital warts is very important. For example, syphilis, chancroid, lymphogranuloma venereum, and herpes simplex for genital ulcer are mistaken for other causes such as Behcet's syndrome, drug eruption, erythema multiforme, amebiasis, trauma, and carcinoma. Confirmatory testings made by cultures, PCR, or serologic studies are important for appropriate treatment and eradication of the disease in both patients and their partners. The physicians treating STDs should make special efforts to be sure that his or her methods of diagnosis and treatment reflect the latest knowledge, since the epidemiologic characteristics and treatment trends are rapidly changing based on newly appearing resistant strains.

From January 1970 to December 1988, 114 patients underwent urethroplasty for traumatic complete disruption of posterior urethra in the Department of Urology, Catholic University Medical College and were followed for 2 to 17 years. The results were as follows : 1. In age distribution age of 73 patients (62%) ranged from 10 to 39 years. 23 patients ( 20.2%) were children and 91 (79.8%) were adults. The most common cause of posterior urethral stricture was traffic accident ( 56.1%) and the most common associated injury was pelvic bone fracture (75.4%). 2. Initial success rate in voiding after primary operation was 78.9 % (90/114 patients) and there was no significant difference of initial success rate in voiding between primary realignment group (81.6%. 31/38 patients) and delayed end-to-end anastomosis group (79.4%. 50/63 patients). 3. In cases of long stricture and multiple failure of urethroplasty, extensive urethroplasties such as skin inlay urethroplasty (17 cases), transpubic urethroplasty (9 cases) and pedicled scrotal skin substitution (3 cases) were required. 4. 111 patients were finally achieved success in voiding postoperatively ( 97.4%, 111/114 patients). 5. According to the 72 patients who have been followed up by interview and questionnaire, late complication rate ( stricture, impotence and incontinence) of the delayed end-to-end anastomosis group (20.0%, 11.1%, 15.6% ) was lower than that of the primary realignment group (27.3 %, 31.8%, 22.7%).

BACKGROUND: We studied the antibiotic sensitivities to the causative microorganisms of acute simple urinary tract infection for recent 3 years. METHODS: We analyzed 112 microorganisms and their antibiotic sensitivities of the 104 patients who were admitted to or visited the Department of Urology, Catholic University St. Marys Hospital and had more than 10cfu/mL on urine culture from June 1996 to January 1999 retrospectively. RESULTS: The chance of gram negative and positive as causative microorganisms was 72.3% and 27.7% respectively. The most common pathogenic microorganisms were Escherichia coli (67.0%) followed by a-hemolytic streptococci, Entercoccus. In gram negative acute UTI, imipenem, sulperanzone showed relatively higher sensitivity, while cotrimoxazole, ampicillin showed relatively lower sensitivity. In gram positive, vancomycin, penicillin showed relatively higher sensitivity, while ampicillin, imipenem showed relatively lower sensitivity. CONCLUSIONS: We consider that gram negative microorganisms, especially E. coli, is the main cause of acute simple UTI. But, we should be concerned about the increase of gram positive organisms and other gram negative organisms besides E. coli. Regarding to the choice of adequate drug in the treatment of UTI, it is necessary to consider the change of pathologic microorganisms.

Purpose: Paclitaxel, on systemic administration, is widely known to be effective in the treatment of bladder cancer. However, the intravesical use of paclitaxel has not been attempted because of its liposolubility and direct toxicity to the bladder mucosa. The purpose of this study was to evaluate the efficacy and toxicity of paclitaxel-loaded glyceryl monooleate (GMO) in the intravesical treatment of superficial bladder cancer, by enhancing its bioadhesiveness and bioavailability. Materials and Methods: 12 mice were divided into two groups, and bladder carcinomas induced by the addition of 0.05% BBN to their drinking water for 12 weeks. Group 1 received an intravesical instillation of 0.1ml GMO-paclitaxel-free buffer and Group 2 an intravesical instillation of 0.1ml GMO-paclitaxel. On day 21, the tumor incidence, bladder weight and toxicity were evaluated. Results: The incidence of cancer in groups 1 and 2 were 83 and 17%, respectively. The incidence of cancer was significantly reduced in group 2 compared to group 1 (p<0.05). There was a tendency for the average bladder weight in group 1 to be heavier than that in group 2, but there was no significant difference (p=0.375). There were no liver, kidney or bone marrow toxicities in either group. Conclusions: Intravesical GMO-paclitaxel therapy may have an inhibitory effect on the growth of superficial bladder cancer in a BBN-induced bladder cancer model; therefore, it could potentially be used in those patients showing little to no response to intravesical Bacillus Calmette- Guerin (BCG) or other anticancer drug therapies.

PURPOSE: Most men with benign prostatic hyperplasia (BPH) have bothersome lower urinary tract symptoms (LUTS). This study aimed to investigate the safety and efficacy of high-performance system (HPS) laser photoselective vaporization of the prostate (PVP) for the treatment of BPH in men with detrusor underactivity (DU). MATERIALS AND METHODS: From March 2009, 371 patients with BPH were divided into 2 groups according to the findings of preoperative urodynamic study: 239 (64.4%) patients with bladder outlet obstruction (BOO) and 132 (35.6%) patients with bladder outlet obstruction with detrusor underactivity (BOO+DU). 120 W HPS laser PVP was performed to resolve the BOO. The perioperative data and postoperative results at 1 month and 12 months, including the International Prostate Symptom Score (IPSS), maximum urinary flow (Qmax), and postvoid residual urine (PVR) values, were evaluated. RESULTS: Compared with the preoperative parameters, significant improvements in IPSS, Qmax, and PVR were observed in each group at 1 and 12 months after the operation. In addition, IPSS, Qmax, and PVR were not significantly different between the BOO and BOO+DU groups at 1 and 12 months after the operation. CONCLUSIONS: Surgery to relieve BOO in the patients with BPH seems to be an appropriate treatment modality regardless of the existence of DU.
