PURPOSE: Accurately measuring urinary urgency is important for diagnosing overactive bladder (OAB) and quantifying improvements in treatment outcome. Various methods have been recommended for evaluating urinary urgency, but these methods assess individual perceptions and preferences. To overcome the subjectivity in measuring urinary urgency, we evaluated the relationship between uroflowmetric parameters and urinary urgency in women with OAB. METHODS: Consecutive female patients with lower urinary tract symptoms (n=110) were prospectively enrolled in this study between April 2011 and September 2012. Individuals with a history of using medications that are known to affect bladder function were excluded. All enrolled patients completed uroflowmetry with a delayed time to voiding (T2V). After urination was completed, patients were asked whether they experienced any urinary hesitancy or urgency at that time. RESULTS: The mean patient age was 56.1 years; 70 out of 110 patients reported some degree of urinary urgency. T2V decreased with increased urgency. Several uroflowmetric parameters were observed to have a significant correlation with urinary urgency. T2V had a meaningful correlation coefficient for individuals with urgency, regardless of the voided volume. There was no significant correlation between the presence of urinary hesitancy and T2V. CONCLUSIONS: We believe that T2V would be a complementary tool for diagnosing and determining the degree of urinary urgency in women with OAB.

PURPOSE: Compared with radical retropubic prostatectomy (RRP), laparoscopic surgery significantly reduces postoperative discomfort, the length of the hospital stay and the length of the convalescent period. However, the procedure of laparoscopic radical prostatectomy (LRP) is difficult to master. Therefore, we considered the surgical technique that is minimally invasive like LRP and it does not require a considerable learning curve and brings good results, like conventional RRP. MATERIALS AND METHODS: From January to May 2006 at our institution, we performed LaMRRP on 7 patients who were diagnosed with clinically localized prostate cancer. Under general anesthesia, a 5cm midline incision was made suprapubically and a 10mm trocar is introduced extraperitoneally at the umbilicus for the camera. The assistant port consisted of a 5mm trocar that was placed for blood suction and for vesicourethral anastomosis. We performed the operation under direct vision through the small window and using a video monitor. The surgical procedures followed the steps employed in conventional RRP. RESULTS: We successfully performed the operation in all cases without any extension of the incision. The mean patient age is 68.4 years old (range: 59-75). The mean operating time was 320 min (range: 290-360). The mean blood loss was 1,380ml (range: 1,150-1,800). There were no major complications. The postoperative pain was noticeably reduced compared with conventional RRP. The urethral catheter was left in place for 18 days (range: 14-25) in all the patients and postoperative cystography showed no leakage. CONCLUSIONS: We could perform LaMRRP with using enhanced surgical views, and there was no long learning curve and no additional expense. The results of LaMRRP were not significantly different from that of conventional RRP. Therefore, LaMRRP could be a useful method for the treatment of localized prostate cancer.

PURPOSE: To explore the effect of bi-parametric MRI-ultrasound (MR/US) fusion prostate biopsy on the detection of overall cancer and significant prostate cancer (sPCa). MATERIALS AND METHODS: We examined 140 patients with suspected prostate cancer lesions on MRI from August 2016 to March 2018. All patients had undergone 3T pre-biopsy bi-parametric (T2 weighted and diffusion-weighted) prostate MRI (bpMRI), and their MRI images were evaluated with Prostate Imaging Reporting and Data System (PI-RADS) version 2.0. MR/US fusion targeted prostate biopsy was performed for lesions with a PI-RADS score ≥3 before systemic biopsy. The results of targeted and systemic biopsy were evaluated in regards to detection rate according to PI-RADS score. RESULTS: Of the patients (mean age=67.2 years, mean prostate-specific antigen level=8.1 ng/mL), 66 (47.1%) and 37 (26.4%) patients were diagnosed with cancer and significant prostate cancer, respectively. The rate of positive targeted biopsy increased with higher PI-RADS score (3: 40.4%, 4: 56.7%, 5: 90.0%). The proportion of significant prostate cancer among positive target lesions was 65.3% (32/49). CONCLUSION: bpMRI is a feasible tool with which to identify sPCa. MR/US fusion biopsy, rather than systemic biopsy, can help identify sPCa. We recommend using supplemental tools to increase prostate cancer detection in patients with PI-RADS 3 lesions.

PURPOSE: We aimed to determine whether 12 core-extended biopsies of the prostate could predict insignificant prostate cancer (IPCa) in Koreans reliably enough to recommend active surveillance. MATERIALS AND METHODS: Two hundred and ninety-seven patients who underwent radical prostatectomy after 12 core-extended prostate biopsies were retrospectively reviewed. 38 cases (12.8%) were shown to be IPCa. RESULTS: The average age was 65.2 years, serum PSA was 5.49 ng/dL, and the PSA density was 0.11. The Gleason scores (GS) were 6 (3+3) in 31, 5 (3+2) in 4, and 4 (2+2) in 3. After radical prostatectomy, higher GS was given in 16 (42.1%), whereas lower GS was given in 1 case (2.6%), as compared with the GS obtained from biopsy. 11 (28.9%) had GS of 7 (3+4) and 5 (13.2%) had GS of 7 (4+3). 6 in GS 7 (4+3) and 1 in GS 7 (3+4) showed prostate capsule invasion and 1 in GS 7 (4+3) had seminal vesicle invasion. Prostate capsule invasion was observed in 1 with GS 6 (3+3). The rate of inaccuracy of the contemporary Epstein criteria was 42.1%. Only PSA density was a reliable indicator of clinically IPCa (odds ratio=1.384, 95% CI, 1.103 to 2.091). CONCLUSION: Diagnosis of IPCa from a prostate biopsy underestimated the true nature of prostate cancer in as many as 42.1% of Koreans.

Epidermal cysts are commonly encountered, slow-growing superficial cysts in the hair-bearing areas of the body, and are usually discovered in the second and fourth decades of life. These cysts tend to be superficial, meaning that they can be easily found by ultrasound and digital palpation at a moderate degree of growth. However, we found a huge testicular cyst that went undetected until old age. In this report, we describe the interesting case of a patient in whom the right testis was totally replaced with an epidermal cyst. The cyst was found by ultrasonography and further evaluated with magnetic resonance imaging. We performed orchiectomy under the impression of an epidermal cyst. The pathologic report confirmed this clinical impression. Over 24 months of follow-up, we did not find any recurrence of a growing mass on the testis.

PURPOSE: Incidence of cancer has been increasing each years. The incidence of genitourinary cancer are also being increased. We aim to describe the time trends in genitourinary cancer incidence in Jeju province. MATERIALS AND METHODS: Age-standardized rates for incidence of genitourinary tract cancer in Korea and world standard population were calculated using the databases from the Jeju Cancer Rigistry from 1999 to 2012. RESULTS: Cancer incidence in Jeju was increased approximately 2-fold from 1217 cases 1999 to 2376 cases in 1999. Prostate cancer occurred most frequently followed by bladder tumor, and kidney cancer in 2012. In the prostate cancer, incidence was increasing every year from 18 cases in 1999 to 110 cases in 2012. Age-standardized incidence rate (ASR) was approximately four time increased, from 3.0 cases in 1999 and 11.2 cases in 2012. Incidence of bladder cancer were 43 cases in 1999 and 27 cases in 2012, ASR of bladder cancer was increased from 5.0 cases in 1999 to 7.5 cases in 2012. Kidney cancer showed constantly reducing the incidence. Peak is 60 cases in 2009 and recent incidence was 37 cases in 2012. There was no significant change in the incidence of testicular cancer, ureter cancer, renal pelvis cancer from 1999 to 2012. CONCLUSIONS: Incidence of cancer has been increasing in Jeju, similar to other area In Korea. Prostate cancer is the most common urological cancer in Jeju province, and kidney cancer incidence is recently decreasing. We should try to prevent genitourinary tract cancer caused obesity and smoking.

PURPOSE: There are few data regarding the epidemiology of hereditary or familial prostate cancer (PCa) in East Asians, especially in Korean men. Therefore, we evaluated the incidence of familial and hereditary PCa and the relation between socioeconomic status and the incidence of nonsporadic prostate cancer (NSPC). MATERIALS AND METHODS: We collected data from all patients who were treated for PCa at our center between November 2009 and January 2010. All patients were either newly diagnosed or had been diagnosed with PCa and seen as outpatients during the study period. RESULTS: In a sample of 218 patients with PCa; 25 (11.5%) were NSPC patients, and 193 (88.6%) were sporadic PCa sporadic prostate cancer (SPC) patients. Overall, 11.5% of the patients had a positive family history. There was one hereditary PCa family (three patients, 1.4%) and 11 familial PCa families (22 patients, 10.1%). Patients were divided into three different age groups. Of these, 18 (9.3%) SPC patients and 6 (24%) NSPC patients were diagnosed with the disease at the age of 55 years or younger (p=0.02). Prostate-specific antigen (PSA) levels in the NSPC group were significantly higher than in the SPC group (7.2+/-3.2 versus 6.3+/-4.9 ng/ml, p=0.042). SPC patients had larger waist circumferences than did NSPC patients (p=0.041). There were no significant differences between the SPC and NSPC groups in terms of socioeconomic status, Gleason score, pathological stage, or pathologic Gleason grade. CONCLUSIONS: East Asian NSPC patients are diagnosed at earlier ages than are SPC patients, even though the incidence of NSPC in the East Asian population is lower than in Western men.

PURPOSE: Recently, intrinsic sphincter deficiency (ISD) has been identified as one important factor in the outcome of stress urinary incontinence (SUI) related surgery. Clinical factors that can predict ISD are uncommon. The aim of this study was to determine predictive clinical factors for ISD in female patients with SUI. METHODS: The patients were classified into 3 groups according to the value of Valsalva leak point pressure (VLPP)>90 cm H₂O (anatomical incontinence, AI), between 61 and 90 cm H₂O (equivocal, EV), and <60 cm H₂O (ISD). All groups underwent a full examination, history evaluation, physical examination, uroflowmetry, and complete urodynamic study. Univariate analysis was performed by chi-square or t-test for categorical variables, respectively. A multivariate study was performed by Pearson correlation analysis in order to get clinical predictors of VLPP<60 cm H₂O. Statistical significance was set at P<0.05. RESULTS: There were 3 groups with a total of 189 patients: 56 patients (AI, 29.7%), 64 patients (EV, 33.8%), and 69 patients (ISD, 36.5%). The univariate analysis revealed a significant difference associated with maximal urethral closing pressure (P=0.03) and Stamey classification (P=0.006) between ISD and AI. The more severe the urinary symptom grade, the higher the frequency of ISD. However, the multivariate analysis showed the independent predictor of ISD is only present in grades II and III symptoms in the Stamey classification (P=0.001). CONCLUSIONS: It was found that the more severe the symptoms of urinary incontinence, the higher the possibility of ISD. In other words, the degree of urinary incontinence was found to be one relevant clinical factor in predicting ISD. This finding may help in evaluating and identifying the appropriate surgical technique for EV. Currently, absolute cutoff value to diagnose ISD has not yet been determined. More research is needed to identify clinical factors that can predict ISD.
