The developmental anatomy of the human superior hypogastric plexus: A morphometrical investigation with clinical and surgical correlations.

The superior hypogastric plexus (SHP) is the part of the autonomic nervous system, which is responsible for the sympathetic innervation of pelvic organs and extrapelvic genitals in humans of both sexes. The SHP also functions as the anatomic pathway for the major part of visceral sensitive fibers originating from pelvic viscera. In this study, the morphology of the SHP was analyzed through anatomical dissections performed both in human adult and fetal cadavers. A computerized morphometrical investigation of the SHP was also performed and the resulting quantitative data statistically assessed. The comparison between fetal and adult SHP revealed that in the male group there was a developmental increase of six times (in height) and of about five times (in width); while in the female group, there was a developmental increase of 3.5 times both in height and width values. In addition, the distance from the superior border of the SHP to the bifurcation of the common iliac arteries presented a developmental increase of about six times in the male group, and about four times in the female group. We propose an original morphological classification with six types, based upon the anatomical arrangement of the nervous fibers in this autonomic plexus.

[Retrospective evaluation of urinary continence in patients submitted to brachytherapy after transurethral resection of the prostate gland]. / Análisis retrospectivo de la continencia urinaria en pacientes sometidos a braquiterapia post-resección transuretral prostática.

INTRODUCTION AND OBJECTIVE: Some candidates for brachytherapy present with a previous history of prostate transurethral resection (TURP). Nonetheless, TURP generates a cavity that may lead to technical difficulties in performing brachytherapy. Such condition make a history of previous TURP a relative contra-indication for brachytherapy. The aim of this study is to evaluate the role of brachytherapy in urinary continence, in a group of patients with previous history of TURP. MATERIALS AND METHODS: In our study, we analysed a group of 16 patients submitted to TURP pre-brachytherapy. The mean quality of life score from ICSmaleSF questionnaire ranged from 0 to 1 before and after brachytheraphy (average: 0,18 -- before; average: 0,20 -- after). There was no estatistically significant difference between the former values (p<0,001). After brachytherapy patients were evaluated for lower urinary tract symptoms. The time interval between TURP and brachytherapy ranged from 30 to 90 days (average: 60 days). Post-brachytherapy follow-up varied between 3 and 60 months (average: 30 months). RESULTS: None of the 16 patients evaluated presented lower urinary tract symptoms nor urinary incontinence. Medical complications observed in patients were: dysuria, erectile dysfunction, scrotal ecchymosis and urinary retention. The cases of dysuria, scrotal ecchymosis and urinary retention observed were of short-duration, the last one with spontaneous resolution after 7 days of vesical catheterism. The patient presenting erectile dysfunction had a good response to oral type 5 fosfodiesterase inhibitor three times a week, after a six month period. CONCLUSION: In accordance with other studies, we believe that with some strategy TURP should not be considered a relative contra-indication for brachytherapy.
