ABSTRACT

PURPOSE: This study investigates gender-based disparities in health-related quality of life (HRQOL) outcomes among kidney stone patients and explores potential contributing factors. METHODS: A retrospective review of medical records at the University of Rochester Medical Center was conducted on 2199 new urolithiasis patients who completed the Wisconsin Stone Quality of Life Questionnaire (WISQOL) standardized on a 0-100 scale. Demographic and clinical data were collected. Statistical analyses included univariate tests, chi-squared tests, and multivariate linear regression. RESULTS: Of the 2199 kidney stone patients, 1085 (49.3%) were female. Females reported significantly lower QoL scores compared to males (71.6 vs 80.7; p<0.001), and this persisted across all domains, including social impact (80.2 vs 86.9; p<0.001), emotional impact (67.3 vs 77.1; p<0.001), disease impact (67.3 vs 77.1; p<0.001), and impact vitality (62.6 vs 72.9; p<0.001). Female gender was identified as an independent predictor of diminished QoL scores, along with younger age, symptomatic status, number of surgeries and presence of a psychosocial comorbidity. CONCLUSIONS: Our findings suggest that women with kidney stones experience lower HRQOL compared to men, even accounting for clinical and demographic factors. While this study provides preliminary insights, additional research is needed to validate these findings in broader and more varied populations.

ABSTRACT

INTRODUCTION: With advancements in laser technology, urologists have been able to treat urinary calculi more efficiently by increasing the energy delivered to the stone. With increases in power used, there is an increase in temperatures generated during laser lithotripsy. The aim of this study was to evaluate the thermal dose and temperatures generated with four laser settings at a standardized power in a high-fidelity, anatomic model. METHODS: Using high-fidelity, 3D printed hydrogel models of a pelvicalyceal collecting system with a synthetic BegoStone implanted in the renal pelvis, surgical simulation of ureteroscopic laser lithotripsy was performed with the Moses 2.0 holmium laser. At a standard power (40 W) and irrigation pressure (100 cm H2O), we evaluated operator duty cycle (ODC) variations with different time-on intervals at four different laser settings. Temperature was measured at two separate locations: at the stone and ureteropelvic junction. RESULTS: Greater cumulative thermal doses and maximal temperatures were achieved with greater ODCs and longer laser activation periods. There were statistically significant differences between the thermal doses and temperature profiles of the laser settings evaluated. Temperatures were greater closer to the tip of the laser fiber. CONCLUSIONS: Laser energy and frequency play an important role in the thermal loads delivered during laser lithotripsy. Urologists must perform laser lithotripsy cautiously when aggressively treating large renal pelvis stones, as dangerous temperatures can be reached. To reduce the risk of causing thermal tissue injury, urologists should consider reducing their ODC and laser-on time.

ABSTRACT

Holmium laser enucleation of the prostate (HoLEP) is a size-independent option for benign prostatic hyperplasia surgical management. Since lower urinary tract symptoms (LUTS) are a quality-of-life issue, studies should prioritize patient-reported outcomes (PROs). This HoLEP review assesses PROs inclusion in the top 20 cited HoLEP studies and defines their limitations. PROs were categorized by domain: LUTS, incontinence, sexual function, pain, hematuria, and patient satisfaction. On review, no top-cited study included all PRO domains. The nuanced patient experience after HoLEP could be better defined via standardized utilization of validated PROs, while also improving comparability between HoLEP studies.

ABSTRACT

As laser technology has advanced, high-power lasers have become increasingly common. The Holmium: yttrium-aluminum-garnet (Ho:YAG) laser has long been accepted as the standard for laser lithotripsy. The thulium fiber laser (TFL) has recently been established as a viable option. The aim of this study is to evaluate thermal dose and temperature for the Ho:YAG laser to the TFL at four different laser settings while varying energy, frequency, operator duty cycle (ODC). Utilizing high-fidelity, 3D-printed hydrogel models of a pelvicalyceal collecting system (PCS) with a synthetic BegoStone implanted in the renal pelvis, laser lithotripsy was performed with the Ho:YAG laser or TFL. At a standard power (40W) and irrigation (17.9 ml/min), we evaluated four different laser settings with ODC variations with different time-on intervals. Temperature was measured at two separate locations. In general, the TFL yielded greater cumulative thermal doses than the Ho:YAG laser. Thermal dose and temperature were typically greater at the stone when compared away from the stone. Regarding the TFL, there was no general trend if fragmentation or dusting settings yielded greater thermal doses or temperatures. The TFL generated greater temperatures and thermal doses in general than the Ho:YAG laser with Moses technology. Temperatures and thermal doses were greater closer to the laser fiber tip. It is inconclusive as to whether fragmentation or dusting settings elicit greater thermal loads for the TFL. Energy, frequency, ODC, and laser-on time significantly impact thermal loads during ureteroscopic laser lithotripsy, independent of power.

ABSTRACT

PURPOSE: To evaluate the thermal profiles of the holmium laser at different laser parameters at different locations in an in vitro anatomic pelvicalyceal collecting system (PCS) model. Laser lithotripsy is the cornerstone of treatment for urolithiasis. With the prevalence of high-powered lasers, stone ablation efficiency has become more pronounced. Patient safety remains paramount during surgery. It is well recognized that the heat generated from laser lithotripsy has the potential to cause thermal tissue damage. METHODS: Utilizing high-fidelity, 3D printed hydrogel models of a PCS with a synthetic BegoStone implanted in the renal pelvis, laser lithotripsy was performed with the Moses 2.0 holmium laser. At a standard power (40 W) and irrigation pressure (100 cm H2O), we evaluated operator duty cycle (ODC) variations with different time-on intervals at four different laser settings. Temperature was measured at two separate locations-at the stone and away from the stone. RESULTS: Temperatures were highest closest to the laser tip with a decrease away from the laser. Fluid temperatures increased with longer laser-on times and higher ODCs. Thermal doses were greater with increased ODCs and the threshold for thermal injury was reached for ODCs of 75% and 100%. CONCLUSION: Temperature generation and thermal dose delivered are greatest closer to the tip of the laser fiber and are not dependent on power alone. Significant temperature differences were noted between four laser settings at a standardized power (40 W). Temperatures can be influenced by a variety of factors, such as laser-on time, operator duty cycle, and location in the PCS.

ABSTRACT

Pediatric nephrolithiasis is increasing in incidence and presents differently compared to adults. We report a case of nephrolithiasis in a pediatric patient, presenting with complaints of emesis, anuria, hematuria, and abdominal distension, leading to a diagnosis of bilateral obstructing cystine stones requiring bilateral percutaneous nephrolithotomy. Pediatric patients with anuria should be evaluated for bilateral nephrolithiasis as an etiology. Calculous anuria requires prompt recognition of the pathologic process and relief of the obstruction with close follow-up and supportive care until definitive stone management. Bilateral percutaneous nephrolithotomy can provide definitive surgical intervention without significant morbidity.

ABSTRACT

INTRODUCTION: Urology has seen shifts in the management of many urologic conditions with the advent of noninvasive procedures that rely on multidisciplinary radiological modalities. This study seeks to analyze changes in urologists, radiologists, and advanced practice providers (APPs) performing uroradiology procedures over time. METHODS: The Centers for Medicare & Medicaid Services Physician/Procedure Summary data from 2010 to 2021 were utilized to examine uroradiology Current Procedural Terminology codes billed by urologists, radiologists, and APPs. Percent of total reimbursement and higher volume procedure count (after excluding providers with <11 procedures by per year) by each provider field was calculated and analyzed for changes in distribution from 2010 to 2021. RESULTS: There were significant changes in all procedures when examining procedure reimbursement distribution in 2010 to 2021 (P < .001). During the period, urology saw decreases in reimbursement proportion as large as 28.7% for kidney cryoablation and increases as large as 14.2% for nephrostomy tube removals. Radiology saw the largest decreases in reimbursement proportion with an 18.9% decrease for nephrostograms, while the largest increase was 23.6% for suprapubic tube placements. APPs saw the largest increase in suprapubic tube changes reimbursement proportion, which rose 14.2% from 2010 to 2021. There were significant changes in proportion in all procedures, except for antegrade stent, renal cryoablation, renal biopsy, and renal thermoablation. CONCLUSIONS: Uroradiology procedures have seen shifts in the distribution of which provider type performs each procedure. Most large changes in reimbursement and procedure proportion were shifted between urology and radiology, with APPs seeing smaller changes.

ABSTRACT

INTRODUCTION: This study aimed to investigate the association between social vulnerability, as measured by the Centers for Disease Control and Prevention's Social Vulnerability Index (SVI), and the quality of life (QoL) of kidney stone patients using the validated Wisconsin Stone Quality of Life Questionnaire (WISQOL). METHODS: A retrospective analysis was conducted on medical records of new urolithiasis patients who completed the WISQOL at the University of Rochester Medical Center kidney stone clinic. The primary outcome was WISQOL score, which was measured across multiple domains. SVI was used to assess social vulnerability. Neighborhoods with high SVI were defined by a threshold greater than or equal to the 75th percentile nationally. Demographic and clinical data were collected. Statistical analyses, including univariate tests and multivariate linear regression, were performed to evaluate the relationships between social vulnerability and disease-specific QoL. RESULTS: A total of 1718 patients were included in the study. One hundred five subjects (6.1%) were from neighborhoods of high social vulnerability. Patients residing in neighborhoods with high social vulnerability (SVI quartile) reported significantly lower QoL scores (69.1 vs 77.2; P = .001) and this persisted across all domains, including social impact (32.6 vs 35.1; P = .002), emotional impact (25.2 vs 27.5; P = .006), disease impact (28.5 vs 31.4; P = .001), and vitality (10.3 vs 11.2; P = .015). Younger age, female sex, and higher number of comorbidities were identified as independent predictors of lower QoL scores. However, non-White race and Latinx ethnicity did not exhibit a significant association with QoL scores. CONCLUSIONS: These findings highlight the negative impact of high social vulnerability on QoL, emphasizing the importance of considering socioeconomic factors in patient care. These results emphasize the need for targeted interventions to support vulnerable populations. While this study offers initial insights, further research is essential to corroborate these outcomes across larger and more diverse populations.

ABSTRACT

Introduction and Objective: Holmium laser enucleation of the prostate (HoLEP) is often offered for symptomatic prostatic enlargement at high risk for bleeding. However, prior studies define clinically significant hematuria (CSH) narrowly as the need for blood transfusion or significant decrease in hemoglobin. We sought to evaluate risk factors contributing to a broader definition of CSH, which may contribute to alteration of clinical course. Methods: We analyzed 164 patients in a prospectively maintained database who underwent HoLEP at a single institution across two surgeons from November 2020 to April 2023. HoLEP was performed using Moses 2.0 (Boston Scientific) laser and the Piranha enucleation system (Richard Wolf). We defined CSH broadly as follows: clot retention, return to operating room, perioperative management variation due to hematuria, or continued gross hematuria past 1 month postoperatively. Univariable and multivariable ANOVAs were used. Multivariable analysis of CSH risk based on the use of antiplatelet (AP) agents or anticoagulants included correction for age, enucleation time (surrogate for case difficulty), and prostate volume. Results: 17.7% (29/164) of our patients developed CSH after HoLEP. Longer enucleation time was a mild risk factor for developing CSH (multivariate odds ratio [OR] 1.01, p = 0.02). The strongest predictor of CSH was the use of anticoagulation or AP agents (OR 2.71 p < 0.02 on univariable analysis, OR 2.34 p < 0.02 on multivariable analysis), even when aspirin 81 mg was excluded. Conclusion: With a broadened definition, 18% of patients developed CSH following HoLEP, which impacted the clinical course. Our data suggest that the current definition of significant hematuria is too narrow and does not capture many patients whose clinical course is affected by hematuria. While safe, anticoagulants and APs significantly predicted an increased CSH risk, and patients should be counseled accordingly.

ABSTRACT

INTRODUCTION: The impact of Medicare reimbursement changes on urology office visit reimbursements has not been fully examined. This study aims to analyze the impact of urology office visit Medicare reimbursements from 2010 to 2021, with a focus on 2021 Medicare payment reforms. METHODS: The Centers for Medicare and Medicaid Services Physician/Procedure Summary data from 2010-2021 were utilized to examine office visit CPT (Current Procedural Terminology) new patient visit codes 99201-99205 and established patient visit codes 99211-99215 by urologists. Mean office visit reimbursements (2021 USD), CPT specific reimbursements, and proportion of level of service were compared. RESULTS: The 2021 mean visit reimbursement was $110.95, up from $99.42 in 2020 and $94.44 in 2010 (both P < .001). From 2010 to 2020, all CPT codes, except for 99211, had a decrease in mean reimbursement. From 2020 to 2021, there was an increase in mean reimbursement for CPT codes 99205, 99212-99215 and decreases in 99202, 99204 and 99211 (P < .001). New and established patient urology office visits had significant migration of billing codes from 2010 to 2021 (P < .001). New patient visits were most commonly as 99204, which increased from 47% in 2010 to 65% in 2021 (P < .001). The most commonly billed established patient urology visit was 99213 until 2021 when 99214 became the most common at 46% (P < .001). CONCLUSIONS: Urologists have seen increases in mean reimbursements for office visits both before and after the 2021 Medicare payment reform. Contributing factors consist of increased established patient visit reimbursements despite decreased new patient visit reimbursements, and changes in level of CPT code billings.

ABSTRACT

Testicular compartment syndrome requires timely diagnosis and intervention but may be challenging. We present a case discussing the presentation and management of testicular compartment syndrome following testicular trauma in an 11-year-old male. The patient presented 24 hours after testicular trauma from a kick with testicular enlargement and sharp pain. Ultrasound showed markedly decreased blood flow and a reactive hydrocele. Testis-sparing intervention included emergent tunica albuginea incision, debridement, and tunica vaginalis flap.

ABSTRACT

Fluoroscopy is essential in percutaneous nephrolithotomy (PCNL) but exposes patients and operating room staff to radiation. We investigated whether a low-dose (LD) protocol could reduce radiation exposure during fluoroscopy-guided access without compromising clinical outcomes. Patients undergoing PCNL with fluoroscopy-guided access at a tertiary care stone center between January 2019 and July 2021 were identified. Prior to September 3, 2020, the Philips Veradius C-arm's default settings were used: standard per-frame dose, 15 pulses per second (PPS) frame rate. After this date, a low-dose protocol was used: reduced per-frame dose, reduced frame rate of 8 PPS for needle puncture and 4 PPS for all other steps. Clinical and radiographical data were retrospectively collected. The primary outcome was cumulative radiation dose. Secondary outcomes were stone-free status (SFS; defined as no fragments ≥ 2 mm) and complications. Multivariate regression analysis was performed. 100 patients were identified; 31 were in the LD group. The LD cohort was exposed to a significantly lower mean cumulative radiation dose of 11.68 mGy compared to 48.88 mGy (p < 0.0001). There were no differences in operative time, fluoroscopy time, stone burden, SFS, or complications. In a multivariable regression model adjusting for several variables, LD protocol was associated with lower radiation dose while skin-to-calyx-distance (STCD) was positively associated with cumulative radiation dose. Low-dose fluoroscopy and decreased frame rate during PCNL decreased radiation exposure fourfold without affecting SFS or complication rates.

ABSTRACT

Emphysematous pyelonephritis (EPN) developing in the contralateral kidney after ureteroscopic laser lithotripsy is an unusual clinical presentation and has never been reported in the literature. After ensuring sterile urine culture a 73-year-old female underwent left ureteroscopy, laser lithotripsy and stent placement for 15mm lower calyceal renal calculus. She was discharged same day and stent removed after 4 days. 1 week later she was admitted with sepsis and found to have EPN in the right kidney, with no evidence of stone or infection in the operated kidney. High index of clinical suspicion and prompt management resulted in successful outcome.

ABSTRACT

PURPOSE: IRIS™ provides interactive, 3D anatomical visualizations of renal anatomy for pre-operative planning that can be manipulated by altering transparency, rotating, zooming, panning, and overlaying the CT scan. Our objective was to analyze how eye tracking metrics and utilization patterns differ between preoperative surgical planning of renal masses using IRIS and CT scans. METHODS: Seven surgeons randomly reviewed IRIS and CT images of 9 patients with renal masses [5 high complexity (RENAL score ≥ 8), 4 low complexity (≤ 7)]. Surgeons answered a series of questions regarding patient anatomy, perceived difficulty (/100), confidence (/100), and surgical plan. Eye tracking metrics (mean pupil diameter, number of fixations, and gaze duration) were collected. RESULTS: Surgeons spent significantly less time interpreting data from IRIS than CT scans (- 67.1 s, p < 0.01) and had higher inter-rater agreement of surgical approach after viewing IRIS (α = 0.16-0.34). After viewing IRIS, surgical plans although not statistically significant demonstrated a greater tendency towards a more selective ischemia approaches which positively correlated with improved identification of vascular anatomy. Planned surgical approach changed in 22/59 of the cases. Compared to viewing the CT scan, left and right mean pupil diameter and number/duration of fixations were significantly lower when using IRIS (p < 0.01, p < 0.01, p = 0.42, p < 0.01, respectively), indicating interpreting information from IRIS required less mental effort despite under-utilizing its interactive features. CONCLUSIONS: Surgeons extrapolated more detailed information in less time with less mental effort using IRIS than CT scans and proposed surgical approaches with potential to enhanced surgical outcomes.

ABSTRACT

The objective is to explore the need for future surgery among patients treated for asymptomatic concurrent contralateral stones versus those that were not. Upon IRB approval, we retrospectively reviewed records of patients who underwent stone surgeries (SWL, URS, PCNL) from 2009 to 2018. Patients were included if they were greater than 18 years old, had a minimum follow-up of 2 years, and had pre-operative imaging. Patients were divided into three groups: bilateral surgery, ipsilateral surgery with, and without asymptomatic concurrent contralateral stones. Cox regression was used to analyze patients' need for future surgery while controlling demographic and comorbid characteristics. Of the 1666 patients included, 51.9% were men. They were 59.7 ± 15 years and had a BMI of 31.3 ± 8.2 kg/m2. During the follow-up of 5.2 ± 2.2 years (range 2-11 years), patients who had bilateral surgery and patients who had ipsilateral surgery without treatment of the asymptomatic concurrent contralateral stones had no difference in the need for future surgery (41.7% vs. 43%, p = 0.585). When stratified by stone size, patients with contralateral stones > 6 mm were more likely to require future surgical treatment than those treated bilaterally (p < 0.001). Our study demonstrates that treating asymptomatic concurrent contralateral stones does not lower the need for future surgical interventions. However, asymptomatic concurrent contralateral stones > 6 mm may portend earlier need for treatment. Therefore, bilateral treatment should be considered at presentation.

ABSTRACT

Although rare, sulfamethoxazole-induced urolithiasis has been reported in patients taking trimethoprim-sulfamethoxazole (TMP/SMX). We present the case of a 79-year-old female who formed sulfamethoxazole stones in the setting of chronic indwelling catheterization with recurrent urinary tract infections (UTIs). The patient was a recurrent stone former with five prior stone composition analyses over a 10-year period varying from calcium phosphate to calcium oxalate, to struvite. We highlight the need for further investigation of this phenomenon given the frequent use of TMP/SMX in stone formers with recurrent infections.

ABSTRACT

OBJECTIVE: To determine if socioeconomic status (SES) correlates with severity of kidney stone disease and 24-hour urine parameters. MATERIALS AND METHODS: An IRB approved prospectively maintained database for nephrolithiasis was retrospectively analyzed for both 24-hour urine results and surgical procedures performed from 2009 to 2019. Severely distressed communities (SDC) were categorized as those with a Distressed Communities Index (DCI), a composite measure of SES, score in the top quartile (lowest for SES). Univariate and multivariate analyses were performed to evaluate the strength of the association of DCI on: stone size at presentation, need for and type of surgical procedure, need for staged surgery and specific stone risk factors in 24-hour urine collections. RESULTS: Surgical procedures were performed on 3939 patients (1978 women) who were not from SDC and 200 (97 women) from SDC. Patients from SDC were older (57.1 years vs 54.2 years; P = .009). Patients from SDC were more likely to undergo proportionally more invasive procedures (17.5% vs 11.6%; P = .011) and require staged surgery at a higher rate (13.0% vs 8.5%; P = .028). Men from SDC had larger stones (12.5 mm vs 9.7 mm; P = .001). Among 24-hour urine results from 2454 patients (1187 women), DCI was not correlated with sodium, calcium, magnesium, volume, oxalate, phosphate, and pH levels. Higher DCI (lower SES) correlated with lower urine citrate (P = .001) and lower urine potassium (P = .002). CONCLUSION: SES correlates with larger stone burden at the time of urologic intervention, requires proportionally more invasive procedures and more staged procedures. Lower SES correlated with lower urine citrate and potassium.

ABSTRACT

OBJECTIVES: To assess clinicopathologic factors on MR/US fusion biopsy that might predict failure of theoretical selection criteria for prostatic hemigland ablation (HA). SUBJECTS AND METHODS: A retrospectively maintained single institution multiparametric MRI database (n = 1667) was queried to identify 355 patients who underwent MR/US fusion biopsy, including both targeted biopsy and concurrent systematic biopsy from December 1, 2014 to June 1, 2018. Clinical, pathological, and imaging variables were assessed on fusion biopsy (Table 1) to determine who met theoretical selection criteria for HA, defined as unilateral intermediate-risk prostate cancer per NCCN criteria (Grade Group [GG] 2 or 3 with prostate-specific antigen <20) and no evidence of extraprostatic extension (EPE) on multiparametric MRI. Predictors of selection criteria failure were then assessed in patients who also underwent radical prostatectomy (RP). Failure of the theoretical HA selection criteria was defined as presence of GG ≧ 2 on the contralateral (untreated) side, or the presence of high-risk disease (any GG ≧ 4 or EPE) in the RP specimen. RESULTS: Of the 355 patients who underwent fusion biopsy, 84 patients met the theoretical selection criteria for HA. Of those patients eligible, 54 underwent RP, 37 (68.5%) of which represented unsuccessful HA selection criteria. Patients no longer met HA selection criteria on the basis of upgrading alone in 6/54 (11.1%), EPE alone in 9/54 (16.7%), bilateral GG 2 or 3 in 16/54 (29.6%) or combined EPE and bilateral GG 2 or 3 in 6/54 (11.1%) cases. In the HA selection failures due to upgrading, three also had EPE, one of whom also had missed contralateral GG ≧ 2 disease. The only factor independently associated with HA failure was any presence of cribriform pattern (HR 7.01, P = 0.021). Perineural invasion on systematic biopsyalso appeared to improve the performance of our multivariable model (HR 5.33, P = 0.052), though it was not statistically significant when using a cutoff of <0.05. Accuracy for predicting successful HA was 0.32 and improved to 0.74 if PNI or cribriform were excluded and 0.84 if both were excluded. CONCLUSIONS: In a retrospective analysis of RP patients who underwent preoperative MRI/US fusion biopsy, current selection criteria for prostatic HA based on NCCN intermediate-risk stratification failed to accurately identify appropriate candidates in 68.5% of patients. Cribriform pattern and PNI detected on biopsy reduced the failure of hemigland selection criteria to 43%.
