Factors Associated With the Differences Between Self-Report Smoking and Urinary Cotinine Criteria.

During self-reporting, respondents underreport their smoking status for various reasons. We aimed to evaluate the difference between smoking status self-reporting and urinary cotinine tests in Korea respondents. Logistic regression analyses were performed to identify factors associated with the differences between self-reporting and urinary cotinine criteria.

Laparoscopic -2port Varicocelectomy with Scarless Periumblical Mini-Incision: Initial Experience in Approach and Outcomes.

Purpose: As with other areas, there have been many efforts for minimally invasive surgery in varicocelectomy. We present our initial experience with laparoscopic varicocelectomy with a two-port scarless periumbilical mini-incision.

Materials And Methods: The study enrolled 18 patients who underwent laparoscopic varicocelectomy with a twoportscarless periumbilical mini-incision from February 2012 to April 2013.

Longitudinal changes in erectile function after thulium:YAG prostatectomy for the treatment of benign prostatic obstruction: a 1-year follow-up study.

This study aimed to evaluate the impact of thulium:yttrium-aluminum-garnet (Tm:YAG) (RevoLix®) laser prostatectomy for the treatment of benign prostatic obstructions on erectile function (EF). A total of 208 patients who underwent Tm:YAG laser prostatectomies participated in this study. All cases were evaluated preoperatively and at 3, 6, and 12 months postoperatively using the International Prostate Symptom Score (IPSS), quality of life (QoL) score, and the International Index of Erectile Function (IIEF-5) questionnaires.

Correlation between postoperative prostate-specific antigen and biochemical recurrence in positive surgical margin patients: Single surgeon series.

Background: To evaluate the relationship between postoperative prostate-specific antigen (PSA) levels and biochemical recurrence (BCR) after radical prostatectomy, especially in patients with positive surgical margins (PSMs).

Materials And Methods: A total of 144 patients who underwent radical prostatectomies performed by a single surgeon without any neoadjuvant or adjuvant treatment were analyzed. Differences in clinicopathological factors were compared by surgical margin status, and the relationship between postoperative PSA level and BCR in patients with PSMs was evaluated.

Transutricular seminal vesiculoscopy in the management of symptomatic midline cyst of the prostate.

Purpose: To evaluate the utility of transutricular seminal vesiculoscopy as a diagnostic and therapeutic option for symptomatic midline cyst of the prostate in patients with hematospermia and symptoms associated with prostatitis.

Materials And Methods: From January 2005 to July 2013, 61 patients with symptomatic (hematospermia, pain on ejaculation, scrotal discomfort) midline cyst of the prostate, who did not improve with medication within a 4-week period, were included. Diagnosis of a midline cyst of the prostate was based on an anechoic round or spheroid-shaped lesion in the median, above the level of the verumontanum, extending into the prostatic base on transrectal ultrasonography (TRUS).

Thulium laser (RevoLix) vaporesection versus vapoenucleation with morcellator (Piranha) for the treatment of benign prostatic obstruction: a propensity-matched multicenter analysis.

Objectives: To compare the efficacy and safety of vaporesection without a morcellator, and vapoenucleation with a morcellator in thulium laser prostatectomy for the treatment of benign prostatic obstruction.

Methods: Between March 2010 and January 2013, 405 patients underwent thulium:yttrium-aluminium-garnet laser prostatectomy. Among these patients, 150 patients who underwent thulium:yttrium-aluminium-garnet laser prostatectomy without a morcellator (n = 75) or with a morcellator (n = 75) were analyzed in a propensity matching study.

Urothelial carcinoma arising from a large ureteral polyp.

We report an unusual case of a urothelial tumor on a ureteral polyp without hydronephrosis. The patient was a 50-year-old male. He had experienced several episodes of gross hematuria.

The washout rate on the delayed CT image as a diagnostic tool for adrenal adenoma verified by pathology: a multicenter study.

Objectives: To establish the undisputed the value of washout rate for adrenal adenoma using delayed enhanced CT, we evaluated diagnostic performance of cut-off value and delayed time of washout rate by final pathologic diagnosis in a multicenter study.

Methods: We reviewed the pathologic and clinical records of 244 patients underwent adrenalectomies at 5 university hospitals between 2005 and 2009. We calculated the mean Housfield units (HU) of adrenal lesion at non-enhancing CT, and early and delayed enhanced CT using the region of interest.

Correlation between lower urinary tract symptoms and premature ejaculation in Korean men older than 40 years old [corrected].

Purpose: To evaluate the correlation between lower urinary tract symptoms (LUTS) and premature ejaculation (PE) in Korean men older than 40 years.

Materials And Methods: In total, 258 men older than 40 years completed the International Prostate Symptom Score (IPSS; total score, storage symptoms [ST], and voiding symptoms [VD]), a 5-item version of the International Index of Erectile Function (IIEF-5), and the Premature Ejaculation Diagnostic Tool (PEDT). The study examined the relationship between LUTS and PE.

Short term effect and safety of antidiuretic hormone in the patients with nocturia.

Purpose: To investigate the short-term safety of antidiuretic hormone in elderly patients with nocturnal polyuria, focus on hyponatremia and others electrolytes disturbances and to assess short-term effects on nocturnal urine output and number of nocturnal voids.

Methods: Between June 2005 and August 2006, a total of 34 patients with nocturnal polyuria were orally administered 0.2 mg desmopressin tablet at bedtime for two weeks.

Growth inhibition of Escherichia coli during heterologous expression of Bacillus subtilis glutamyl-tRNA synthetase that catalyzes the formation of mischarged glutamyl-tRNA1 Gln.

It is known that Bacillus subtilis glutamyl-tRNA synthetase (GluRS) mischarges E. coli tRNA1 Gln with glutamate in vitro. It has also been established that the expression of B.
