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.

Introduction:
Prostate cancer is a significant health problem worldwide. Transrectal ultrasound guided biopsy has limitations in the detection of clinically significant disease, hence, new imaging including multiparametric MRI and MRI targeted biopsy is developed. In most centers, reading and contouring of the prostate and identification of significant lesions on MRI are performed by radiologists. In this institution, these steps are performed by a urologist.
Objective:
To determine the clinically significant cancer detection rate in patients undergoing MRI fusion-targeted and random systematic prostate biopsy where MRI PIRADS scoring, identification of lesions and contouring are performed by a trained urologist in a Philippine tertiary hospital.
Methods:
This is a cross-sectional study of patients who underwent MRI fusion prostate biopsy in the Philippine General Hospital (PGH) from June 2021 to June 2023. Clinically significant cancer (csCancer) detection rates were calculated for MRI fusion prostate biopsy, random systematic prostate biopsy, and PIRADS scoring. Concordance was also determined between PIRADS scores and histopathological results.
Results:
Forty six (46) patients who underwent MRI fusion biopsy in PGH were included in the study, representing a total of 90 lesions identified by urologists using mpMRA with PIRADS scores of at least 3. Of the patients, 13 (14.4%) were diagnosed with csCancer, while a large proportion was diagnosed with benign prostatic tissue. The csCancer detection rate of MRI fusion biopsy was 28.3% (13/46) and 8.7% (4/46) for random biopsy. The csCancer detection rate was 11.1%, 14.6%, and 36.4% for PIRADS 3, 4, and 5, respectively.
Conclusion
The detection rate of clinically significant prostate cancer using MRI fusion-targeted prostate biopsy based on urologist-performed MRI reading and contouring was superior to random systematic approach. The positive predictive value of PIRADS scores when interpreted by urologists was lower compared to reported values in the literature and did not show concordance. This may reflect lowered thresholds for labeling prostate lesions as suspicious in urologists.

von Hippel Lindau syndrome is a rare genetic disease which may present with bilateral adrenal masses requiring surgical intervention. Previous practice at UP-PGH was to perform outright total adrenalectomy on pathologic adrenal glands and rely on lifelong steroid replacement for patients who had both adrenals removed. Presented here is a case of a patient diagnosed with von Hippel Lindau syndrome with bilateral adrenal masses, surgically managed initially with open adrenalectomy on the right side, followed by the first ever performed minimally invasive cortical sparing adrenalectomy at UP-PGH on the left side.
