RESUMO
PURPOSE: Transurethral resection of the prostate (TURP) is still the gold standard method to treat benign prostatic hyperplasia (BPH). Transurethral vaporization of the prostate (TUVP) is compared with the transurethral resection of benign prostatic hyperplasia. PATIENTS AND METHODS: Over a 10-month period, 78 patients presenting with moderate and severe symptomatic BPH were randomized into two groups. A total of 38 patients underwent TURP, and 40 men underwent TUVP. The protocol included urinary flow rate (Qmax), symptomatology evaluated by the International Prostatic Symptom Score (I-PSS), and an ultrasonographic estimate of the postvoiding residual volume (PVR). The TUVP was carried out using a regular loop with the electrical source set at 250 to 300 W in the pure cutting mode. The same technique was used in the TURP, but the electrosurgical unit was set at 50 to 80 W for cutting and 50 W for hemostasis. The mean follow-up was 17 months (range 11-23 months). RESULTS: The data showed significant improvement in the symptom score, maximum flow rate, and postvoiding residual urine volume after treatment (P<0.01) in both groups. Comparing the symptom score, there was no difference between the two techniques (P = 0.88), the same occurring with the PVR (P = 0.78). However, the Qmax was higher after TURP (P = 0.02). The amount of tissue resected showed no statistical difference between the two techniques (P>0.05). Operative time, postoperative irrigation, catheter removal, and hospital stay were better with TUVP (P = 0.001). There was a statistically significant difference (P = 0.003) when we compared the occurrence of retrograde ejaculation with TURP (32%) and TUVP (65%) The TUVP using a regular loop, in addition to the advantage of the equipment and technique already being familiar to urologists, is efficient and reduces capital expenditure. CONCLUSION: The TUVP is a remake of TURP, with higher energy offering better results.

OBJECTIVES: To investigate the impact of partial penectomy on the quality of life of patients with carcinoma of the penis. METHODS: Fourteen patients who had undergone partial penectomy for penile cancer were studied. Their median age was 50.5 years and the median time of follow-up was 11.5 months. The quality of life was evaluated in three dimensions: social adjustment, sexuality, and emotional state. The patients underwent a semistructured interview and were asked to complete the Overall Sexual Functioning Questionnaire, the Social Problem Questionnaire, the General Health Questionnaire, and the Hospital Anxiety and Depression Scale. RESULTS: In 9 (64%) patients, the overall sexual function was normal or slightly decreased. Only 2 (14%) men had precarious or absent sexual function. The masculine self-image and the relationship with their partners remained practically unchanged in all the patients. Sexual interest and satisfaction remained normal or slightly reduced in 9 and 12 patients, respectively. The frequency of sexual intercourse was unchanged or slightly decreased in 9 patients. Three patients had no sexual intercourse after surgery. No significant levels of anxiety and depression were found. Within the areas of living conditions, family life, and interactions with other people, all the patients remained as they were before the surgery. CONCLUSIONS: Patients who undergo partial penectomy for penile cancer can maintain the quality of life (in social, psychological, and sexual terms) at levels similar to those that existed in the period before surgery.
