Abstract
Objective

To assess erectile dysfunction in patients with prostate cancer undergoing surgery by radical prostatectomy, laparoscopic prostatectomy or robotic prostatectomy.

Material and methods

Systematic review of literature based on a search strategy (2000-10) in MedLine, Embase, Cochrane Library, CRD, ECRI, and Hayes. Mesh terms used were “Prostatectomy”, “Prostatic Neoplasm”, “Transuretral Resection Prostate”, “Impotence” and as free terms “erectile dysfunction” and “prostatectomy”. Studies included patients with prostate cancer who underwent radical prostatectomy with open surgery (retropubic), laparoscopic or robotic surgery.

Results

Ten observational studies with moderate quality and 29 case series with low quality were selected. Observational studies showed lower percentages of erectile dysfunction after intervention in the patients who underwent robotic surgery (3–51%). Radical surgery (36–91%) and laparoscopic surgery showed higher values of impotence. In the studies that compared surgery versus radiotherapy, the results were better for radiotherapy (3–72% erectile dysfunction). In the case series, lower percentages of erectile dysfunction were shown in patients who underwent robotic surgery (22%), the following was for laparoscopic surgery (40%) and open radical prostatectomy (41.4%).

Conclusions

This result should be considered with caution because of the low methodological quality of the studies included. However, the different surgical techniques assessed showed similar effects in the two types of studies included and we found that robotic surgery presented lower percentages of sexual impotence.

Resumen
Objetivo

Evaluar la aparición de la disfunción eréctil en pacientes con cáncer de próstata sometidos a prostatectomía radical (PR) retropúbica, prostatectomía laparoscópica y/o prostatectomía robótica.

Material y métodos

Revisión sistemática de la literatura médica mediante búsqueda bibliográfica (2000–2010) en MedLine, Embase, Cochrane Library, Center for Review Dissemination, ECRI y Hayes. Los términos Mesh fueron «Prostatectomy», «Prostatic neoplasm», «Transuretral resection prostate», «Impotence» y los términos libres fueron «erectile dysfunction» y «prostatectomy». Los estudios incluían pacientes con cáncer de próstata intervenidos para la extirpación de la glándula mediante cirugía abierta (retropúbica), laparoscópica o robótica.

Resultados

Se seleccionaron diez estudios observacionales de calidad moderada y 29 series de casos de baja calidad. Los estudios observacionales presentaban los menores porcentajes de disfunción eréctil en pacientes intervenidos mediante cirugía robótica (3–51%). La PR retropúbica (36–91%) y la laparoscópica registraban cifras superiores de aparición de impotencia. Los estudios que comparaban intervenciones, cirugía y radioterapia obtenían con las radiaciones menores índices de disfunción sexual (3–72%). En las series de casos, los menores porcentajes de disfunción eréctil acontecieron en pacientes con cirugía robótica (22%), seguido de cirugía laparoscópica (40%) y de PR retropúbica (41,4%).

Conclusiones

Los resultados, aunque deben interpretarse con cautela dada la limitada calidad de los estudios, presentan efectos similares en la evaluación de las diferentes técnicas quirúrgicas, observándose que la cirugía robótica registra los menores porcentajes en relación con la aparición de impotencia sexual.
