Effects of resection volume on postoperative micturition symptoms and retreatment after transurethral resection of the prostate.

Purpose: Despite advances in technology, such as advent of laser enucleation and minimally invasive surgical therapies, transurethral resection of the prostate (TURP) remains the most widely performed surgical technique for benign prostatic hyperplasia (BPH). We evaluated resection volume (RV)-derived parameters and analyzed the effect of RV on post-TURP outcomes.

Methods: This observational study used data from patients who underwent TURP at two institutions between January 2011 and December 2021 Data from patients with previous BPH surgical treatment, incomplete data, and underlying disease affecting voiding function were excluded.

Does the Time Interval from Biopsy to Radical Prostatectomy Affect the Postoperative Oncologic Outcomes in Korean Men?

Background: Prostate cancer (PC) is the second most common type of cancer in men worldwide and the fifth most common cancer among Korean men. Although most PCs grow slowly, it is unclear whether a longer time interval from diagnosis to treatment causes worse outcomes. This study aimed to investigate whether the time interval from diagnosis to radical prostatectomy (RP) in men with clinically localized PC affects postoperative oncologic outcomes.

Do positive surgical margins predict biochemical recurrence in all patients without adjuvant therapy after radical prostatectomy?

Purpose: The objective was to study whether positive surgical margins (PSMs) predict biochemical recurrence (BCR) in all patients without adjuvant therapy after radical prostatectomy (RP).

Materials And Methods: We retrospectively reviewed the medical records of patients who underwent RP for prostate cancer at Veterans Health Service Medical Center from 2005 to 2011. BCR was defined by a prostate-specific antigen (PSA) value ≥0.

Efficacy of alternative antiandrogen therapy for prostate cancer that relapsed after initial maximum androgen blockade.

Purpose: We evaluated the effectiveness of second-line maximum androgen blockade (MAB) with an alternative antiandrogen in patients who relapsed after initial MAB.

Materials And Methods: We retrospectively analyzed 47 patients with prostate cancer who relapsed after initial MAB, including surgical or medical castration combined with antiandrogens, from January 1998 to December 2009. When the serum prostate-specific antigen (PSA) level was increased on three consecutive occasions, we discontinued the antiandrogen and then administered an alternative antiandrogen.

Results of urine culture and antimicrobial sensitivity tests according to the voiding method over 10 years in patients with spinal cord injury.

Purpose: We studied the results of urine cultures and antimicrobial sensitivity tests according to the voiding method used by spinal cord injury (SCI) patients over a recent 10-year period.

Materials And Methods: We retrospectively analyzed 1,236 urine samples and their antimicrobial sensitivity tests for 112 patients who had used only one voiding method between January 2000 and December 2009. The voiding methods were classified into four groups: clean intermittent catheterization (CIC), suprapubic catheterization, urethral Foley catheter, and spontaneous voiding.

Pathologic results of radical prostatectomies in patients with simultaneous atypical small acinar proliferation and prostate cancer.

Purpose: The incidence of adenocarcinoma on a subsequent biopsy following a diagnosis of atypical small acinar proliferation (ASAP) ranges from 34% to 60%. We reexamined radical prostatectomy (RP) specimens of patients diagnosed as having synchronous ASAP with prostate cancer (PCa) to evaluate pathological entities and the clinical significance of ASAP.

Materials And Methods: From January 2007 to December 2008, a total of 118 patients who had been diagnosed with adenocarcinoma on prostate needle biopsy underwent RP.
