[Long term results of congenital penile curvature treated with cavernosa corpora rotation.]

INTRODUCTION

Congenital penile curvature (PCC) is a disorder caused by an alteration in the embryonic development of the urethra and the corporacavernosa, which causes difficulty in penetration, requiring surgical correction when inter course is impossible.

OBJECTIVE

To analyze the results of the surgical treatment of the IPC by means of rotation of the corpora cavernosa (RCC) described and modified by Shaeer. PATIENTS AND METHODS: Ten patients diagnosed with PCC with impossibility to inter course, were operated in a period of 36 months. Prior to the intervention,we applied the IIEF-5 questionnaire, measured the length of the penis and the angle of curvature throughself-photographs in three projections. By subcoronal approach,we perform denudation of the penis. On both sides of the urethra we incised Buck's fascia and released the neurovascular bundle from the ventral to the dorsal side. We generate an artificial erection evidencing the curvature. On the dorsal aspect of both corpora cavernosa, we made two incisions in the external longitudinal layer of the tunica albuginea. We sutured the internal and external edges of both incisions together with a 4/0 non-reabsorbable monofilament continuous suture, checking the correction of the curvature by means of an artificial erection. The patients were discharged the day after the intervention. The penile length and curvature were determined in the sixth month, and the IIEF-5 questionnaire. For the comparison of means we used the Mann-Whitney U test.  RESULTS: The mean age was 26.8 years. The average follow-up was 20.7 months (12-31) and the median was 24. Before the intervention, the average curvature was 68.5° (50-90°); the average length 14.2 cm (10-18) and the IIEF-5 of 21. After surgery, the average length was 13.7 cm, the residual curvature the IIEF-5 of 25. There were no statistically significant differences between pre and postoperative penile length,(p=0.08). Nine patients assured that they would under go the same intervention again. CONCLUSIONS: RCC is an effective therapeutic alternative to the techniques of plication or lengthening of the tunica albuginea for the treatment of PCC, main tainingits long-term results.

[Comparison of monopolar versus bipolar transurethral resection of the prostate: Evaluation of the impact on sexual function]

OBJECTIVES

To assess the effects of monopolar transurethral resection of the prostate (M-TURP) and bipolar TURP (B-TURP) on overall sexual function.

METHODS

From December 2014 to September 2016, 100 eligible candidates with benign prostatic hyperplasia were prospectively recruited and randomized 1:1 into M-TURP/B-TURP arms (58 and 42 patients, respectively) and followed up at 1, 3 and 6 months. A univariate and multivariate analyses using the chi-squared test and a logistic regression model were performed. We recorded the age, medical conditions such as hypertension and diabetes, history of smoking, preoperative prostatic volume, prostatic symptoms scale, sexual function assessment, surgeon experience, resected grams, percentage of resected tissue and presence of retrograde ejaculation. Prostatic symptoms and erectile function (EF) assessment were quantified using self-administered IPSS scores and IIEF-5, respectively, at baseline and in each subsequent visit.

RESULTS

Mean age was 66 years (50-82). No statistical differences were found between both groups regarding medical comorbidities, preoperative IPSS and IIEF-5. Mean prostatic volume was 37.2 cm³ (10-68) and mean amount of resected tissue was 11.75g (6-58). At baseline 77,6% of patients has severe LUTS, and 50% has moderate-severe erectile dysfunction. Univariate analyses show that in both groups, history of diabetes mellitus, age and preoperative IIEF-5 were associated with poor EF. However, multivariate analyses revealed that age was the only factor associated with a poor EF. These results were similar at 3 and 6 postoperative months. We did not find an association between surgeon experience, source of energy employed or percentage of resected tissue with the development of postoperative retrograde ejaculation (52%). At first postoperative month, 44% of patients were still referring moderate prostatic symptoms and 50% had severe erectile dysfunction maintained at 6 months in both groups.

CONCLUSIONS

There were no differences between the source of energy employed and changes on overall sexual function. Age is the only factor associated with a poor EF status.
