Complete stone clearance using a modified supine position: initial experience and comparison with prone percutaneous nephrolithotomy.

Background And Purpose: The recently described Galdakao-modified supine Valdivia position for percutaneous nephrolithotomy (PCNL) has become increasingly popular. We have made further modifications to this and describe our recent experience compared with our previous prone cases.

Patients And Methods: From April 2011, all patients undergoing PCNL have been placed in the modified supine position.

Prostate weight is the preferred measure of prostate size in radical prostatectomy cohorts.

Objective: To evaluate the accuracy of calculated prostate volume variables in a radical prostatectomy (RP) cohort, as many recent studies use these measures of prostate size instead of prostate weight. To determine whether this accuracy could be improved by modifying the mathematical model used in the volume estimation.

Patients And Methods: Patients who underwent RP for prostate cancer at our associated institutions had calculated specimen volumes and weights from RP specimens determined at one pathology institution and transrectal ultrasonography (TRUS) volumes were recorded preoperatively (n= 236).

Acute management of priapism in men.

Unlabelled: What's known on the subject? and What does the study add? Priapism is a rare event. However, various medications and medical conditions may increase the risk. Priapism can be ischaemic, non-ischaemic or stuttering.

Prostate tumour volume is an independent predictor of early biochemical recurrence in a high risk radical prostatectomy subgroup.

Aims: To assess if accurately determined tumour volume variables could serve as independent predictors of early biochemical recurrence in high risk prostate cancer patients who underwent radical prostatectomy.

Methods: Tumour volume variables were calculated by digital planimetry in 269 prostatectomy specimens of patients with high risk prostate cancer. The associations to biochemical progression of tumour volume and clinicopathological variables, including age, pre-operative prostate specific antigen (PSA) levels, final Gleason score, pathological T stage, and surgical margins, were examined using univariate and multivariate Cox proportional hazards analyses.
