The Effect of Transurethral Resection of the Prostate on Erectile Function in Patients with Benign Prostatic Hyperplasia

PURPOSE: The aim of this study was to investigate the effect of transurethral resection of the prostate (TURP) on erectile function. MATERIALS AND METHODS: A total of 108 patients treated with TURP were retrospectively evaluated. All patients were evaluated 1, 3, and 6 months after TURP by use of the International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), peak urinary flow rate (Qmax), and post-void residual urine (PVR). RESULTS: One and 3 months after TURP, the erectile function domain score of the IIEF was significantly decreased. However, after 6 months, there was no longer a significant decrease in the erectile function domain score. The change in erectile function was compared with the IPSS score. There was no statistically significant correlation, but patients who had better voiding symptoms after TURP had improved erectile function. CONCLUSIONS: Our study showed that there was a significant decrease in erectile function for 3 months after TURP. However, no significant change in erectile function was observed 6 months after TURP.

Newly Discovered Pseudoaneurysm after Embolization of a Renal Arteriovenous Fistula with a Pseudoaneurysm following a Renal Stab Wound

Post-traumatic arteriovenous fistula (AVF) and pseudoaneurysm are rare, and mostly occur in stab wound patients. Suspected AVF and pseudoaneurysm requires angiography, with planned simultaneous embolization. Superselective embolization is generally a safe and effective treatment modality for AVF and pseudoaneurysm with minimal associated morbidity. Rare complications of the embolization do occur, including renal abscess, postembolization syndrome, impaired renal function, pulmonary embolism caused by migration of coils, and allergic reaction. We present here the case of a man who presented with a newly discovered pseudoaneurysm after embolization of a renal AVF with pseudoaneurysm after a renal stab wound.

The Changes of Serum Prostate-specific Antigen after Ejaculation / 대한비뇨기과학회지

PURPOSE: Prostatic manipulation and surgery have been shown to increase serum prostate-specific antigen (PSA). We studied the effect of ejaculation on the serum PSA levels. MATERIALS AND METHODS: We evaluated 131 men(16 to 64 years old) who had no history of surgery or inflammatory disease of the urogenital tract. The total serum PSA, free PSA, serum total testosterone, free testosterone, luteinizing hormone(LH), and follicular stimulating hormone(FSH) were evaluated 1 hour after ejaculation. RESULTS: A PSA level was detected in all the men. There were statistically significant changes of the serum PSA level before and after ejaculation. We compared the parameters between increased PSA group and the decreased PSA group. There were significant differences between the two groups on comparison of the total prostate volume(25.4+/-3.6g vs 15.1+/-4.2g, respectively) and the transition zone volume(7.1+/-2.7g vs 5.3+/-1.1g, respectively). CONCLUSIONS: Based on our data, ejaculation affects the serum PSA concentration in young men, and there seems to be a physiological relationship between ejaculation and the PSA level. The larger the prostate volume, the more ejaculation has an effect on the serum PSA level.
