Interexaminer reliability of transrectal ultrasound for estimating prostate volume.

Purpose: We investigated the interexaminer reliability of transrectal ultrasound measurement of total prostate and transition zone volume among 3 examiners with various levels of experience.

Materials And Methods: A total of 121 patients 39 to 82 years old (average plus or minus standard deviation 60.7 +/- 10.

Interexaminer reliability and validity of a three-dimensional model to assess prostate volume by digital rectal examination.

Objectives: To evaluate the interexaminer reliability and accuracy compared with transrectal ultrasound (TRUS) of a three-dimensional (3D) model and other scales to improve the estimation of prostate volume by digital rectal examination (DRE).

Methods: Volunteers from a urology clinic (n = 121) were examined independently by three examiners with different levels of experience in randomized order. During DRE, the examiners estimated the prostate size in increments of 5 g, using various rating scales and a 3D sizing model, without access to the findings of the other investigators.

The so-called "placebo effect" in benign prostatic hyperplasia treatment trials represents partially a conditional regression to the mean induced by censoring.

Objectives: To study the variability of assessment instruments (symptom questionnaires and flow rate recordings) in healthy volunteers during repeat administration in short intervals. To study the effect of inclusion criteria-based censoring of patients during screening for benign prostatic hyperplasia (BPH) treatment trials on the outcome of subsequent tests.

Methods: One hundred forty-five male volunteers without known prostatic diseases with a mean age of 52 years (range 23 to 83) were given the American Urological Association (AUA) Symptom Index (SI), BPH Impact Index (II).

Safety and efficacy of the Alexandrite laser for the treatment of renal and ureteral calculi.

Objectives: To assess the safety and efficacy of the Alexandrite laser for intracorporeal lithotripsy of renal and ureteral stones in conjunction with ureterorenoscopy or percutaneous nephrostolithotomy.

Methods: We retrospectively analyzed the records of 137 patients with 169 calculi in 143 renoureteral units who were treated with the Alexandrite laser via a retrograde (91.5%) or antegrade (8.

Microwave thermotherapy for benign prostatic hyperplasia with the Dornier Urowave: results of a randomized, double-blind, multicenter, sham-controlled trial.

Objectives: To study the efficacy and safety of a new transurethral microwave thermotherapy device (the Urowave) in the treatment of men with clinical benign prostatic hyperplasia (BPH) in a randomized, double-blind, sham-controlled trial.

Methods: A total of 220 patients (mean age 66.2 years) with clinical BPH, an American Urological Association symptom index (AUA SI) of 13 points or more, and a peak flow rate of 12 mL/s or less were enrolled and randomized 2:1 for active versus sham treatment.

Correlation between prostate size estimated by digital rectal examination and measured by transrectal ultrasound.

Objectives: To correlate prostate size estimates performed by single or multiple examiners through digital rectal examination (DRE) with volume measured by transrectal ultrasound (TRUS) and to propose measures for predicting prostate volume using DRE estimates in clinical settings.

Methods: Data from four sources were analyzed: (1) the Olmsted County community study of 397 patients examined by a single urology nurse, with TRUS measurements done by multiple examiners; (2) a community study in Stirling, Scotland, involving 480 patients with DRE and TRUS performed by one urologist; (3) baseline data from the Veterans Affairs Cooperative Study No. 359 in 1222 patients with DRE and TRUS measurements by multiple personnel at 31 centers; and (4) a clinical series of 100 men with DRE and TRUS by a single urologist.
