Purpose@#This study aimed to evaluate the relationship between prostate volume and lower urinary symptom (LUTS) in subjects undergoing health checkup and to know the usefulness of TRUS in health screening. @*Materials and Methods@#The study was conducted in 883 men aged ≥20 years who underwent TRUS for health screening. All participants had filled in the international prostate symptom score (IPSS) and were tested for prostate-specific antigen; prostate volume, central gland volume, and transitional zone index were measured using TRUS. We analyzed the differences in the IPSS by prostate volume and differences in prostate volume by severity of LUTS and correlation between prostate volume and each component of IPSS. @*Results@#There were differences in the total IPSS, storage score, and voiding score between the subjects with prostate volumes of ≥30 mL or not (p=0.027, p=0.037, and p=0.029, respectively). However, the differences were found only for urgency and weak stream. The volume of the severe symptom group was bigger than those of the mild and moderate symptom groups (p=0.002 and p=0.014). The correlation between prostate volume and IPSS was significant only for the between the central volume and nocturia (r=0.112, p<0.01). @*Conclusions@#The relationship between prostate volume and urinary symptoms showed significant but low correlation and found only in some components. For the accurate diagnosis, it would be more useful to accompany various voiding-related surveys in addition to TRUS during health screening. (Korean J Urol Oncol 2020;18:53-60)
Résumé
PURPOSE: To analyze the clinical parameters correlated with early recovery of urinary continence after radical prostatectomy, with a focus on urethral mobility during pelvic contraction at catheter removal. METHODS: We prospectively analyzed 67 patients who underwent prostatectomy for prostate cancer at Jeju National University Hospital from January 2015 to June 2018. At the time of catheter removal, a cystography was performed in 67 men (median age, 65 years; range, 55–76 years) who had undergone robot-assisted laparoscopic prostatectomy. The vertical length of bladder neck movement between relaxing and contracting the pelvic muscles was measured. The correlation between the rate of continence recovery and the length of urethral movement was also assessed. All participants were divided into 2 groups according to the length of bladder neck elevation. Group 1 had ≥0.6 cm of elevation, while group 2 demonstrated <0.6 cm of elevation. RESULTS: A reverse correlation existed between the length of urethral movement and the recovery rate of urinary continence (r=–0.488, P<0.001). The optimal cutoff value for length of urethral movement was found to be 0.6 cm among patients (area under the curve, 0.703). A statistically significant difference was observed between group 1 (length≥0.6 cm) and group 2 (<0.6 cm) (P<0.05). Multivariate regression analysis showed that urethral movement predicted the postoperative urinary incontinence. CONCLUSIONS: The extent of bladder neck elevation after robot-assisted laparoscopic prostatectomy, which can be easily evaluated using cystography, may be a good predictor of the recovery of urinary continence.

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: 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.

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.

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: To examine the possibility of reducing the number of cores per prostate biopsy in elderly patients with high levels of prostate-specific antigen (PSA) without significantly lowering the detection rate of prostate cancer. MATERIALS AND METHODS: Two hundreds sixteen men with PSA levels >20 ng/mL who underwent prostate biopsies from May 2009 to April 2013 were retrospectively reviewed. With the help of magnetic resonance imaging (MRI), the laterality of the dominant tumor burden in patients was determined. The results of targeted biopsies were compared with those of conventional biopsy procedures. RESULTS: The mean age and PSA level were 79.5 years and 81.3 ng/mL, respectively, and the overall diagnostic rate of sextant biopsies was 81.9% (177/216). MRI was able to show the tumor burden in 189 of the 216 patients. The detection rate of transrectal ultrasonography (TRUS)-guided targeted biopsies was 87.3% (165/189). Detection rates were comparable with conventional biopsies (81.9% [177/216]) (p=0.23). Of the 177 men in whom the results of the sextant biopsy were positive, 12 men (6.8%) with PSA levels <29 ng/mL did not have any cancer cells according to targeted biopsies. However, all other patients were diagnosed with prostate cancer using the abovementioned techniques. CONCLUSIONS: We believe that TRUS-guided targeted biopsies of the prostate in elderly men with high PSA levels could reduce the number of unnecessary cores per biopsy. However, a risk of detection loss remains. Therefore, we recommend that at least a sextant biopsy should be performed, even in elderly patients, in order to detect prostate cancer.

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.

Gastrointestinal stromal tumors (GISTs) are an unusual and heterogeneous group of spindle cell tumors that can also appear on the exterior of the gastrointestinal tract (extra-GISTs). Despite the fact that extra-GISTs or large rectal GISTs can lead to the clinical impression of a prostatic mass, these tumors are, in general, excluded in the differential diagnosis of spindle cell tumors observed on prostate needle biopsy. Here, we present, in detail, a case of an extra-GIST identified on prostatic biopsy; the tumor was previously believed to be a primary prostatic stromal sarcoma in the differential diagnosis. Every investigator should check for KIT (CD117) in immunohistochemical staining to rule out an extra-GIST prior to diagnosing a solitary prostatic tumor, specialized prostatic stromal tumor, or leiomyosarcoma on prostate needle biopsy.

PURPOSE: Intravesical protrusion of the prostate (IPP) can affect voiding. We evaluated the improvement in lower urinary tract symptoms and patient satisfaction after laser prostate photovaporization in benign prostatic hyperplasia (BPH) patients with or without IPP. MATERIALS AND METHODS: This prospective study included 134 patients who underwent GreenLight HPS laser photoselective vaporization prostatectomy (PVP) between January 2010 and July 2011 patient. Preoperative IPP was evaluated by using the retroflexed view from flexible cystoscopy. evaluation included complete medical history, International Prostate Symptom Scores (IPSS), maximum flow rate (Qmax), postvoid residual (PVR), serum prostate-specific antigen (PSA), and transrectal ultrasonogram. Changes from baseline in Qmax, PVR, total IPSS, and IPSS subscores (voiding and storage) were analyzed at postoperative months 1, 3, and 6. RESULTS: The patients' mean age was 66.6+/-7.8 years. Mean serum PSA and prostate volume were 1.7+/-1.5 ng/mL and 42.9+/-16.7 g, respectively. No significant differences existed between the IPP and no IPP groups in preoperative prostate volume, total IPSS, PSA, or lasing time and energy. The mean follow-up duration was 6.2+/-1.9 months. IPP patients showed significant improvements in total IPSS and voiding subscores at months 1 and 3. Improvements in the quality of life score and storage subscore were not significantly different between the groups. Qmax was significantly improved at 6 months postoperatively in the IPP group versus the no IPP group. CONCLUSIONS: Among patients who underwent PVP for BPH, the IPP group showed more symptom improvement, especially in voiding symptoms, than did the no IPP group. Preoperative cystoscopy is helpful for evaluating IPP and for anticipating postoperative outcome.

PURPOSE: To evaluate the effectiveness of digital rectal-compression immediately after transrectal prostate biopsy (P-bx) for improving the accuracy of prostate cancer (PCa) staging. MATERIALS AND METHODS: Between July 2008 and June 2010, 94 consecutive patients who had a radical prostatectomy were included in our retrospective analysis. The exclusion criteria included a history of previous P-bx and surgery, a biopsy performed in another hospital, a number of biopsy cores different from 12, or a condition interfering with bleeding assessment. The subjects were divided into two groups, compression and non-compression. All enrolled patients took magnetic resonance imaging (MRI) for PCa staging. RESULTS: The compression and non-compression groups were comparable with respect to several baseline characteristics. However, the total hemorrhage score of intraprostatic bleeding was significantly different between the groups, even with adjustment for the time from biopsy to MRI (compression:15.4+/-2.32, non-compression: 24.9+/-2.43, p<0.001). The intra-prostatic cancer location matching rate was higher in the compression group (78.0%) than in the non-compression group (70.2%) (p=0.011). Overall accuracy of staging in compression and non-compression groups was 84.7% and 77.3%, respectively. CONCLUSION: Our results demonstrate that digital rectal compression performed immediately after prostate biopsy to reduce intraprostatic hemorrhage improves the accuracy for detection of PCa using MRI.

PURPOSE: We review our experience using a new and easily removable ureteral catheter in patients who underwent complicated ureteral reimplantation. Our goal was to shorten hospital stay and lower anxiety during catheter removal without fear of postoperative ureteral obstruction. MATERIALS AND METHODS: Between April 2009 and September 2010, nine patients who underwent our new method of catheter removal after ureteral reimplantation were enrolled. Patients who underwent simple ureteral reimplantation were excluded from the study. Following ureteral reimplantation, a combined drainage system consisting of a suprapubic cystostomy catheter and a ureteral catheter was installed. Proximal external tubing was clamped with a Hem-o-lok clamp and the rest of the external tubing was eliminated. Data concerning the age and sex of each patient, reason for operation, method of ureteral reimplantation, and postoperative parameters such as length of hospital stay and complications were recorded. RESULTS: Of the nine patients, four had refluxing megaureter, four had a solitary or non-functional contralateral kidney and one had ureteral stricture due to a previous anti-reflux operation. The catheter was removed at postoperative week one. The mean postoperative hospital stay was 2.4 days (range 1-4 days), and the mean follow-up was 9.8 months. None of the patients had postoperative ureteral obstructions, and there were no cases of migration or dislodgement of the catheter. CONCLUSION: Our new method for removing the ureteral catheter would shorten hospital stays and lower levels of anxiety when removing ureteral catheters in patients with a high risk of postoperative ureteral obstruction.

Résumé
The present study evaluated optimal baseline prostate-specific antigen (PSA) level at different ages in order to determine the risk of developing prostate cancer (CaP). We analyzed 6,651 Korean men, aged 40-69 yr. The serum PSA levels for these men were measured at one institute from 2000 to 2004 and were determined to be between 0-4 ng/mL. Patients were divided into 4 groups of 25th-percentile intervals, based on initial PSA level. Of these, the group with an increased risk was selected, and the optimal value was determined by the maximal area under a receiver-operating characteristic curve within the selected group. The risk of CaP diagnosis was evaluated by Cox regression. The mean follow-up period was 8.3 yr. CaP was detected in 27 of the 6,651 subjects. CaP detection rate was increased according to age. The optimal PSA value to distinguish the risk of CaP was 2.0 ng/mL for 50- to 69-yr-olds. Patients with a baseline PSA level greater than the optimal value had a 27.78 fold increase in the prostate cancer risk. Baseline PSA values are useful for determining the risk of developing CaP in Korean men for 50- and 69-yr-old. We suggest that PSA testing intervals be modified based on their baseline PSA levels.

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.

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.

The bladder is involved in less than 4% of inguinal hernias. Inguinoscrotal bladder hernias are difficult to diagnose, and less than 7% are diagnosed preoperatively. Inguinoscrotal bladder hernias are usually asymptomatic. However, they can result in significant complications, such as bladder necrosis or acute renal failure. Accurate diagnosis is crucial to avoid bladder injury during surgery and other complications. Here we report the case of a 64-year-old man who presented with a scrotal mass. Ultrasonography of the scrotal mass showed a nonspecific cystic mass. During surgery, the mass was revealed to be a herniated bladder.

PURPOSE: We aimed to evaluate the efficacy of warm water sitz baths in patients who have undergone transurethral resection of the prostate (TURP) owing to lower urinary tract symptoms secondary to benign prostatic hyperplasia. MATERIALS AND METHODS: We reviewed the records of 1,783 patients who had undergone TURP between 2001 and 2009. In the warm water sitz bath group, patients were instructed to sit in a tub containing lukewarm water at 40-45degrees C for 10 minutes each time. Patients were advised to perform the procedure for at least 5 days immediately after the removal of a Foley urethral catheter. The differences in post-TURP complications between the warm water sitz bath group and the no sitz bath group were compared. RESULTS: After TURP, 359 of the 1,561 patients performed a warm water sitz bath. Complications after TURP, such as hemorrhage, urinary tract infection, urethral stricture, and acute urinary retention were found in 19 (5.3%) and 75 (6.2%) patients in the sitz bath and no sitz bath groups, respectively (p=0.09). There was a significant difference in postoperative complications such as urethral stricture between the warm sitz bath group and the no sitz bath group (p=0.04). The group that did not undergo warm water sitz bath treatment showed a 1.13-fold increased risk of rehospitalization within 1 month after TURP due to postoperative complications compared with the warm water sitz bath group (odds ratio [OR]=1.134; 95% confidence interval [CI], 1.022 to 1.193; p=0.06). CONCLUSIONS: Warm water sitz bath treatment reduced postoperative complications such as urethral stricture. These results suggest that large-scale prospective studies are needed to establish an ideal method and optimal duration of sitz baths.

PURPOSE: In this study, we detail our initial experience with robot-assisted laparoscopic radical cystectomy(RLRC) with ileal conduit urinary diversion(ICUD) and describe the stepwise surgical procedure. MATERIALS AND METHODS: Four men underwent RLRC with extracorporeal ICUD for muscle invasive bladder cancer. RLRC was performed by a single surgeon using the da Vinci(TM) robot system(Intuitive Surgical, Sunnyvale, USA) with four robot arms. The surgical specimen was extracted through the sub-umbilical incision, and ICUD was also achieved through the sub-umbilical incision by extracorporeal technique. RESULTS: The mean operative time was 355+/-49.8 minutes, and the mean estimated blood loss was 550+/-57.7ml. The mean hospital stay was 12+/-2.9 days. There were no major complications. On surgical pathology, one patient had pTis, one patient had pT1, and two patients had pT3 transitional cell carcinoma of the bladder. There were no positive surgical margins or lymph nodes. The mean number of dissected lymph nodes was 17+/-4.6(range: 12-23). CONCLUSIONS: Despite limited experience, RLRC is a feasible procedure with minimal blood loss, shorter hospital stay, and may be an alternative to the open technique.
