: Multiparametric MRI (mpMRI) of the prostate is recently becoming more and more utilized in the detection of prostate cancer. Studies have shown that a higher PIRADS score correlated to a higher chance of obtaining a clinically significant prostate cancer but few studies have correlated PIRADS score to a specific Gleason score. OBJECTIVE: This study aimed to determine the concordance of PIRADS score to the Gleason score result of MRI ultrasound fusion-guided prostate biopsy. METHODS: All patients who had at least a PIRADS 2 lesion on mpMRI and underwent MRI ultrasound fusion-guided biopsy of the prostate from August 2018 up to November 2019 at St. Luke’s Medical Center, Global City were included in the study. An ambispective collection of data was done until the ideal sample size of greater than 100 positive lesions was obtained, in order to derive concordance rate. RESULTS: One hundred and sixty-two patients were included in the study with a total of 212 lesions analyzed. Forty three percent were benign while 57% were found to be malignant. PIRADS 2 lesions had zero high grade cancers, and the percentage steadily increased with 37.8% of PIRADS lesions considered high grade. Concordance was computed to be 0.38 showing a fair, direct concordance between PIRADS and Gleason score with significant result (p<0.05). CONCLUSION A result of PIRADS 4 or 5 lesion on mpMRI will have a higher urgency of doing a prostate biopsy and subsequent management to prevent unfavorable outcomes as opposed to PIRADS 3 lesions.

INTRODUCTION: Robot-assisted laparoscopic radical prostatectomy is now considered the gold standardtreatment of prostate adenocarcinoma in the modern world. There are two approaches to the precisedissection of seminal vesicles (anterior and posterior) during a laparoscopic radical prostatectomy,each of which with unique advantages and disadvantages. Primarily, the authors compared theintraoperative and oncological outcomes of these two approaches. Secondary objective included theestablishment of the minimum number of cases before a surgeon can enter the competent phase of thelearning curve. MATERIALS AND METHODS: Chart review was performed on 111 patients who underwent RALP from2014-2016 performed by 3 experienced robotic surgeons with interchangeability of role as consoleoperator. Two arms were developed based on the approach of seminal vesicle dissection, that is,anterior and posterior approach. Cumulative summation of the console time was performed to obtaina chart with a) negative slope-learning phase and b) positive slope-competent phase. Patients underthe competent phases were included for analysis. RESULTS: There were no significant differences in age, body mass index, prostate volume, preoperativeprostate specific antigen (PSA), gleason score and oncologic risk. Pathology was almost similar inmajority of cases under the anterior approach arm being gleason 7 (3+4) and posterior approach armbeing gleason 6 (3+3). With a p-value of <0.05, console time was significantly shorter in the posteriorapproach at 121±25.95 when compared to anterior approach at 148±30.25 minutes. The otherperioperative and postoperative outcomes were not significantly different between the groups. CONCLUSION Posterior approach has provided a shorter console time, while the overall oncologic andperioperative outcomes for both approaches were similar. The learning curve for the anterior approachis less steep than that of the posterior approach with only 14 versus 26 consecutive cases, respectively,to be able to competently perform RALP.

Benign mesenchymal tumors of the urinary bladder are extremely rare. This is a case of a 56- year old female presenting with an enlarging abdomen initially managed as a case of an ovarian new growth. Aside from the ruptured ovarian mass, a urinary bladder mass was also noted intraoperatively and a surgical dilemma was resolved by imaging review. The patient underwent exploratory laparotomy, enterolysis, total hysterectomy, bilateral salpingooophorectomy, and partial cystectomy. Final histopathology identified the bladder tumor to be a leiomyoma. The patient had an uneventful postoperative course. Awareness of this clinical entity and presentation will aid in diagnosis and management.

OBJECTIVE: To establish the incidence of postoperative bacteriuria (PBU) in patients after undergoing transurethral resection of the prostate (TURP) using sterile distilled water as irrigating fluid, and determine the possible risk factors for its development. METHODS: A retrospective cohort study of patients who underwent TURP using distilled water as irrigating fluid from 2014-2018 at a tertiary government hospital was performed. Included were patients who had urine culture results upon admission, treated with antibiotics or received antibiotic prophylaxis within 24 hours prior to operation, as appropriate, and had a repeat culture prior to discharge. PBU was defined as the presence of significant (≥ 105 CFU/mL) bacteriuria upon catheter removal in patients with either no growth on preoperative urine culture or growth of a different organism from that of the preoperative culture. Chi-square and Student’s T-test were used to compare those with and without PBU and attributable risk (AR) values were determined for identified risk factors. RESULTS: Eighty-four patients with a mean age of 65 (± 6.32) years were included. Sixteen (19%) patients developed PBU. Preoperative catheterization and resection time of more than 30 minutes were found to be associated with the development of PBU (p=0.020 and 0.047, respectively), with AR of 24.24% (95% CI [13.90,34.58]) and 22.86% (95% CI [13.02,32.69]). Age, resected prostate weight, and diabetes mellitus were not found to be associated with PBU. CONCLUSION Postoperative bacteriuria rate of 19% was noted with the use of distilled water as irrigant during TURP. Significant risk factors for its development included preoperative catheterization and prolonged resection times.

INTRODUCTION AND OBJECTIVES: Percutaneous nephrolithotripsy (PCNL) is the first-line treatment for stone burden >2 cm. The aim of this study was to determine factors that would affect stone free rates after PCNL. Preoperative and intra-operative variables were correlated to the patient’s post-operative outcomes to find a link, or lack thereof, to stone-free outcomes. METHODS: A retrospective study of patients who underwent primary PCNL was done over a 1-year period. The association of the stone characteristics (based on Guy stone score), stone burden, operative time, lithotripsy time, number of access tracts, and location of access tracts to the stone-free status were analyzed. RESULTS: One hundred thirty patients who underwent PCNL were included in this study. Stone free rate was 77.69% (101/130) while 23 of the 29 patients with residual stones (22%) (29/130) required further treatment. The 30-day overall morbidity rate was 8.46% (11/130). Guy stone score (GSS) and stone burden were found to be significantly associated with stone-free status. Patients with GSS grade I had the highest stone-free rate of 95.45% while patients with GSS Grade IV had the lowest stone-free rate at 30.00%. After multivariate analysis, stone burden (OR 1.176; 95% CI 1.084- 1.275; p 0.00) and GSS 4 (OR 15.374; 95% CI 1.164- 202.980; p 0.04) were significant independent risk factors for stone-free status. CONCLUSION Stone clearance and complication rate after PCNL of the present study were 78% and 8.5%, respectively, comparable with published data. A higher Guy’s stone score and a higher stone burden were significantly associated with retained stones post-PCNL.

OBJECTIVE: This study aims to evaluate the effects on biochemical recurrence (BCR) of the followingproposed prognostic factors after radical prostatectomy (RP): patients' clinical T stage, Gleason gradegroup (GG) of RP specimen, technique of operation used (open RP vs. robot-assisted laparoscopicRP), presence of positive surgical margin (PSM), length of PSM, GG at PSM, extraprostatic extension(EPE) at PSM, and presence of detectable PSA at 4-6 weeks after RP. It also aims to identify whichamong the aforementioned variables are independent predictors of risk for BCR. PATIENTS AND METHODS: This is a retrospective study. Included in the study were patients who underwentRP (Open and Robot-assisted Laparoscopic technique) at two tertiary hospital branches of an academicmedical center from April 2009 to December 2015 with histopathology reports read by a singleurologic pathologist and with complete follow- up for at least one year. Excluded were those whounderwent RP but without complete follow- up. Using Pearson chi-square and z-test with level ofsignificance set at 0.05, the clinicopathologic variables including: patients clinical stage, GG of RPspecimen, length of PSM, GG at positive margins, presence of EPE at positive margins, and presenceof detectable PSA after the surgery were assessed in order to know which among these factors werepredictive of BCR. Multinomial regression analysis was also used to identify which among the variableswere independent predictors of risk for BCR. RESULTS: A total of 165 patients underwent RP from April 2009 to December 2015, among which 72patients were eligible for inclusion in the final analysis. Clinical T2 stage was found to be a predictorof BCR with odds ratio of 13.000 (95%CI: 3.705 - 45.620; p < 0.001) as compared to stage T1. GGof final histopathology report of prostatectomy specimen was found to be a predictor of BCR, asthose with grade groups 4 and 5 had significantly increased risk of BCR with odds ratio of 70.778(95%CI: 8.207 - 610.426; p < 0.001) as compared to those with grade groups 1 to 3. Patients withpositive margins had increased risk of BCR, with odds ratio of 13.458 (95%CI: 13.472 - 52.171; p <0.001) compared to those with negative margins. GG at the PSM was found to be a predictor of BCR,with a grade grouping of 4 or 5 at the positive margin predicting BCR with odds ratio of 20.625(95%CI: 2.241 - 189.847; p = 0.008) as compared to grade grouping of 1 or 2 at the margin. DetectablePSA after RP was found to be a predictor of BCR, with odds ratio of 115.000 (95%CI: 19.457 -679.712; p < 0.001) as compared to undetectable PSA after RP. Technique of RP (p = 0.177), measuredlength of PSM (p = 0.713), and EPE at PSM (p = 0.146) were not found to predict BCR. Furthermore,clinical T stage (p = 0.007) and detectable PSA after RP (p < 0.001) were found to be independentpredictors of BCR among the risk factors examined. CONCLUSION Of the independent variables examined, clinical T stage, GG of RP specimen, presenceof PSM, GG at positive margins, and detectable PSA were found to be significant predictors of BCR. Technique of RP, measured length of PSM, and EPE at PSM were not found to predict BCR.Furthermore, multivariate analysis showed that only clinical T stage and detectable PSA after RPwere independent predictors of BCR. Attentive assessment of these predictors in the preoperativeperiod should aid the urologist in clinical decision-making and in advising patients regarding theirprognosis.
