Fibrous Pseudotumor in the Testicular Tunica / 대한비뇨기과학회지

Fibrous pseudotumor of the testicular tunics is uncommon lesion. They typically arise as painless scrotal masses that may be associated with a hydrocele or history of trauma or infection. Two-thirds involve the tunica vaginalis testis, with infrequent involvement of other scrotal structures. Once excised, these lesions behave in a benign fashion. Typically, these masses are multinodular, but in rare cases they are diffuse, band-like myofibroblastic proliferations that encase the testis. We report here on a case of fibrous pseudotumor of the tunica vaginalis in 76 year-old patient. (Korean J Urol 2006;47:1130-1132)

Photoselective Vaporization of the Prostate(PVP) using KTP Laser for Treatment of Benign Prostatic Hyperplasia(BPH) / 대한남성과학회지

PURPOSE: PVP using a high-power potassium-titanly-phosphate(KTP) laser offers safe and efficacious surgical therapy for men with symptomatic BPH. To demonstrate its efficacy, safety and durability, we present the results of PVP for treatment of BPH with 12 month follow-up. MATERIALS AND METHODS: 104 consecutive men with symptomatic BPH underwent PVP with an 80 W KTP laser (Laserscope) between July 2003 and August 2004. All underwent preoperative and postoperative evaluation, including assessments of international prostate symptom score(IPSS), quality of life(QOL), peak urinary flow rate(Qmax), post-void residual volume(PVR), prostate specific antigen(PSA), and ultrasound prostate volume(PV). Secondary outcome parameters included surgical time, anesthesia, and length of catheterization. Follow-up assessment occurred at 1, 3, 6, and 12 months. Data were analyzed using the Wilcoxon signed rank test. RESULTS: Preoperative mean PV was 57.2+/-4.2 ml. PV decreased to 38.9, 35.4, 32.8 and 35.8 at 1, 3, 6 and 12 months (p <0.01 versus preoperative value). Mean improvements in IPSS, QOL, Qmax, and PVR at 12 months were 67%, 81%, 138% and 94%, respectively(p <0.001). Mean operative time was 26.3+/-15.0 minutes. Anesthesia included pudendal and prostatic block(n=102) and spinal anesthesia(n=2). Ninety-nine(95%) patients were treated as outpatients( <12 hrs) and the remaining 5 patients were admitted for 1 or 2 hospital days. Mean catheterization times were 9.8+/-3.1 hours(range 0~72), with 28(27%) patients not requiring a catheter post-operatively. Minor complications included mild hematuria lasting 3 weeks(3.8%), transient post-operative retention(2.9%), urge incontinence(1.9%), transient dysuria(25%), frequency(21.2%), urgency(17.3%) and retrograde ejaculation(41%). CONCLUSIONS: These results demonstrate that PVP is safe and efficacious for the treatment of symptomatic BPH. Long follow-up will further validate this new modality as the standard for surgical treatment of BPH.

Percutaneous Sclerotherapy of Simple Renal Cyst Using Minocycline HCl / 대한비뇨기과학회지

PURPOSE: Sclerotherapy is performed additionally to improve the outcome of aspiration in simple renal cyst. Ethanol has been used most commonly as a sclerosing agent, however, drainage is necessary which complicates the procedure. For this reason, we used minocycline HCl as a sclerosing agent without need to be drained and evaluated the results. MATERIALS AND METHODS: From June 1990 to May 1999, 140 patients who underwent percutaneous minocycline HCl sclerotherapy for simple renal cyst were evaluated. Among them, 10 patients were missed during follow-up and 7 patients had bilateral simple renal cysts. The simple renal cysts were aspirated under ultrasonography, and then minocycline HCl 100mg mixed with 5ml normal saline was injected into the cyst per 50ml of aspirated cyst fluid. The follow-up ultrasonography was performed at posttreatment 3, 6 and 12 months. The recurred cases were retreated with same procedure. RESULTS: Among 137 renal cysts of 130 patients who could be followed up, 70 renal cysts (51.1%) were totally collapsed and 53 renal cysts (38.7%) showed a 50% or more decrease in cyst volume after first treatment. All 14 persistent renal cysts (10.2%) showed a 50% or more decrease in cyst volume after second or third treatment. Catheterization for drainage of the sclerosing agent was not needed. There were only some minor complications such as nausea, vomitting and local pain that subsided within one day with only symptomatic treatment. CONCLUSIONS: These results shows that percutaneous minocycline HCl sclerotherapy is simple, safe and effective and can be a alternative first line therapy of simple renal cyst.

Anatomic and Histologic Changes of the Testis after Long-Term Estrogen Exposure in Transsexuals / 대한남성과학회지

PURPOSE: To investigate the anatomic and histologic changes of testis as a result of long-term estrogen exposure on male MATERIALS AND METHODS: Fourteen testes were harvested from 14 consecutive male-to-female transsexuals who had sex reassignment operation in Dong-A University Hospital from March 1991 to March 1997. Age at inception of estrogen therapy was 16 years to 24 years. The duration of estrogen therapy was 2-12 years (mean 7.4 years). The dose and method of estrogen treatment regimen was variable, but about 20 mg (intravenous) monthly during first year. Sperm analysis, volume of testis and histologic change of testis were compared to the duration of estrogen therapy. RESULTS: The mean volume of semen was 1.8 ml(0.5~3 ml), and oligozoospermia, azoospermia or asthenospermia were observed in 12 cases (85.7%) by means of sperm analysis. The mean volume of testis was 17.3 ml(15~23ml). In light microscopic examination of the testis, near-normal histologic finding was noted in 3 cases(21.4%), spermatocytic arrest in 8 cases(57.2%) and geminal cell aplasia in 3 cases (21.4%). CONCLUSION: As the duration of estrogen therapy was longer, there was a tendency that volume of semen, sperm count and motility were reduced and the histologic change of seminiferous tubules was severe. It was considered that the negative feedback of estrogen on hypothalamic-pituitary-gonadal axis, the down regulation of estrogen receptors and the direct effect of estrogen might produce the adverse effect on male reproductive system by testicular change with maturation arrest, germ cell aplasia, end-stage testis and peritubular fibrosis and reduced fertility after long-term estrogen exposure.

The Effect of Treatment of Erectile Dysfunction with Electrical Stimulation / 대한남성과학회지

PURPOSE: In recent year, erectile dysfunction patients are increasing, and some of them want to increase their erectile function without using medication or surgical methods, In this study we attempted to find the value of electrical stimulation with electrical stimulation machine Hi-DREAM 328(TM) made in Korea as a treatment method of no definite underling disease caused erectile dysfunction patients. MATERIALS AND METHODS: In 22 cases erectile dysfunction patients we treated them two times per week for 4 weeks totally 8 times above mentioned machine, each session was spent for 1 hour 48 minutes. We checked IIEF-5 (International Index of Erectile Function-5) score repeatedly for comparing the change of IIEF-5 score pretreatment, 1 month after treatment and 3 month after treatment. And we compared the effect of treatment as comparing the IIEF-5 score changing each time. RESULTS: Total IIEF-5 score of pretreatment was 9.6+/-5.5, 1 month and 3 month after electrical stimulation were 17.9+/-2.9, 16.2+/-2.9, respectively. In the patients with venous leakage, IIEF-5 score was no increase definitely following electrical stimulation. But in the case of abnormal SPACE, pretreatment of IIEF-5 score was 12.1+/-5.2, 1 month and 3 month after electrical stimulation were 18.1+/-7.6, 16.5+/-7.4, respectively. We found that IIEF-5 score were increased in no definite organic caused erectile dysfunction patients, and there was significant correlation statistically (p<0.05) in erectile function, maintenance of erection, intercourse satisfaction, overall satisfaction. The remaining effect after treatment was decreased in time follow up. But the erectile function was preserved at comparing before treatment. CONCLUSIONS: We suggest that electrical stimulation is one of the treatment modalities in the treatment of no definite underling disease caused erectile dysfunction patients rather than vascular abnormalities as like venous leakage.

A Case of Bilateral Cerebellar Tuberculomas

Hematogenous spread from tuberculous lesions of other parts of the body represent the origin of intracranial tuberculomas. In most series of the literature, the cerebellum has about two thirds and the cerebral hemispheres about one third of the intracranial tuberculomas. It may occurs as a single lesion, but multiple intracranial tuberculomas varies from 10% to 33% of the cases due to the hematogenous spread. Calcium deposits are rare, occurring in about 6% of cases. Ramamurthi and Varadarajan described the two types of the intracranial tuberculoma; 1. Superficial and vascular type, produces early focal signs of increased intracranial pressure. 2. deep and avascular type, accompanied by signs of increased intracranial pressure. We have been experienced in one case of symmetrical and bilateral cerebellar tuberculomas probably originated from the pulmonary lesion.
