Evaluation of vascular changes in cavernous arteries by penile doppler ultrasound in patients undergoing laparoscopic radical prostatectomy.

Patients undergoing radical prostatectomy for prostate cancer may experience erectile dysfunction (ED). Age of patients, experience of the surgeons and existence of ED before surgery are factors related to its appearance. The objective of the study was to assess the hemodynamic changes produced in the cavernous arteries in patients undergoing laparoscopic radical prostatectomy (LRP) measured with penile Doppler ultrasound (PDUS).

[Posterior Retroperitoneoscopic adrenalectomy in the prone position. Initial experience.].

Objective: Transperitoneal laparoscopic adrenalectomy (TLA) is considered the treatment of choice for small and benign adrenal tumors. In the recent years, posterior retroperitoneoscopic adrenalectomy (PRA) has gained popularity due to its advantages over TLA, presenting a shorter surgical time and a faster recovery without increasing complications. Conversely, a greater learning curve is considered because the use of a different and unusual surgical field.

Effect of muscle density in patients with metastatic prostate cancer administered androgen deprivation therapy.

Introduction: Sarcopenia is a syndrome characterized by the loss of muscle mass and strength. The study objective was to determine the association between muscle density and overall survival (OS) in patients with metastatic onset prostate cancer (MPCa).

Materials And Methods: This was a retrospective study of patients diagnosed with MPCa between 2009 and 2015 who received androgen deprivation therapy alone as initial treatment.

Laparoscopic partial nephrectomy: Comparative study of the transperitoneal pathway and the retroperitoneal pathway.

Introduction: Laparoscopic partial nephrectomy is the recommended treatment for tumours smaller than 4cm in cases where it is feasible. Depending on the location of the tumour, the transabdominal or direct retroperitoneal pathway may be considered.

Objective: To compare the transperitoneal (TPPN) and direct retroperitoneal (RPPN) partial nephrectomies performed between 2007 and 2016.
