Abstract
INTRODUCTION We aimed to assess the impact of discharge instruction (DCI) readability on 30-day postoperative contact with the healthcare system. MATERIALS AND METHODS Utilizing a multidisciplinary team, DCI were modified for patients undergoing cystoscopy, retrograde pyelogram, ureteroscopy, laser lithotripsy, and stent placement (CRULLS) from a 13th grade to a 7th grade reading level. We retrospectively reviewed 100 patients including 50 consecutive patients with original DCI (oDCI) and 50 consecutive patients with improved readability DCI (irDCI). Clinical and demographic data collected including healthcare system contact (communications [phone or electronic message], emergency department [ED], and unplanned clinic visits) within 30 days of surgery. Uni/multivariate logistic regression analyses used to identify factors, including DCI-type, associated with increased healthcare system contact. Findings reported as odds ratios with 95% confidence intervals and p values (< 0.05 significant). RESULTS There were 105 contacts to the healthcare system within 30 days of surgery: 78 communications, 14 ED visits and 13 clinic visits. There were no significant differences between cohorts in the proportion of patients with communications (p = 0.16), ED visits (p =1.0) or clinic visits (p = 0.37). On multivariable analysis, older age and psychiatric diagnosis were associated with significantly increased odds of overall healthcare contact (p = 0.03 and p = 0.04) and communications (p = 0.02 and p = 0.03). Prior psychiatric diagnosis was also associated with significantly increased odds of unplanned clinic visits (p = 0.003). Overall, irDCI were not significantly associated with the endpoints of interest. CONCLUSIONS Increasing age and prior psychiatric diagnosis, but not irDCI, were significantly associated with an increased rate of healthcare system contact following CRULLS.

Does Moses technology improve the efficiency and outcomes of standard holmium laser lithotripsy? A systematic review and meta-analysis. Cent European J Urol 2022; 75:409-417. [PMID: 36794033 PMCID: PMC9903166 DOI: 10.5173/ceju.2022.156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 10/09/2022] [Accepted: 10/10/2022] [Indexed: 02/17/2023] Open
Abstract
Introduction Retrograde ureteroscopy with holmium laser lithotripsy (HLL) is a standard treatment for urolithiasis. Moses technology has been shown to improve fragmentation efficiency in vitro; however, it is still unclear how it performs clinically compared to standard HLL. We performed a systematic review and meta-analysis evaluating the differences in efficiency and outcomes between Moses mode and standard HLL. Material and methods We searched the MEDLINE, EMBASE, and CENTRAL databases for randomized clinical trials and cohort studies comparing Moses mode and standard HLL in adults with urolithiasis. Outcomes of interest included operative (operation, fragmentation, and lasing times; total energy used; and ablation speed) and perioperative parameters (stone-free rate and overall complication rate). Results The search identified six studies eligible for analysis. Compared to standard HLL, Moses was associated with significantly shorter average lasing time (mean difference [MD] -0.95, 95% confidence interval [CI] -1.22 to -0.69 minutes), faster stone ablation speed (MD 30.45, 95% CI 11.56-49.33 mm3/min), and higher energy used (MD 1.04, 95% CI 0.33-1.76 kJ). Moses and standard HLL were not significantly different in terms of operation (MD -9.89, 95% CI -25.14 to 5.37 minutes) and fragmentation times (MD -1.71, 95% CI -11.81 to 8.38 minutes), as well as stone-free (odds ratio [OR] 1.04, 95% CI 0.73-1.49) and overall complication rates (OR 0.68, 95% CI 0.39-1.17). Conclusions While perioperative outcomes were equivalent between Moses and standard HLL, Moses was associated with faster lasing time and stone ablation speeds at the expense of higher energy usage.

A novel upper tract ureteroscopic biopsy technique: the "form tackle". Int Braz J Urol 2021; 48:367-368. [PMID: 34907769 PMCID: PMC8932032 DOI: 10.1590/s1677-5538.ibju.2021.0499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 07/14/2021] [Indexed: 11/26/2022] Open
Abstract
Introduction and Objective: Upper tract urothelial carcinoma (UTUC) represents 5% of all urothelial malignancies (

). Accurate pathologic diagnosis is key and may direct treatment decisions. Current ureteroscopic biopsy techniques include cold-cup, backloaded cold-cup and stone basket (
4
–
6
). The study objective was to compare a standard cold-cup biopsy technique to a novel cold-cup biopsy technique and evaluate histopathologic results. Materials and Methods: We developed a novel UTUC biopsy technique termed the “form tackle” biopsy. Ureteroscope is passed into ureter/renal collecting system. Cold-cup forceps are opened and pressed into the lesion base (to engage the urothelial wall/submucosal tissue) then closed. Ureteroscope/forceps are advanced forward 3-10mm and then extracted from the patient. We compared standard versus novel upper tract biopsy techniques in a series of patients with lesions ≥1cm. In each procedure, two standard and two novel biopsies were obtained from the same lesion. The primary study aim was diagnosis of malignancy. IRB approved: 21-006907. Results: Fourteen procedures performed on 12 patients between June 2020 and March 2021. Twenty-eight specimens sent (14 standard, 14 novel) (Two biopsies per specimen). Ten procedures with concordant pathology. In 4 procedures the novel biopsy technique resulted in a diagnosis of UTUC (2 high-grade, 2 low-grade) in the setting of a benign standard biopsy. Significant difference in pathologic diagnoses was detected between standard and novel upper tract biopsy techniques (p=0.008). Conclusions: The “form tackle” upper tract ureteroscopic biopsy technique provides higher tissue yield which may increase diagnostic accuracy. Further study on additional patients required. Early results are encouraging.

Does MOSES pulse modulation reduce short-term catheter reinsertion following holmium laser enucleation of the prostate? Investig Clin Urol 2021; 62:666-671. [PMID: 34729966 PMCID: PMC8566787 DOI: 10.4111/icu.20210182] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/27/2021] [Accepted: 07/13/2021] [Indexed: 11/21/2022] Open
Abstract
Purpose Previously published studies have shown small prostate size, capsular perforation and intraoperative bladder distension are associated with failed trial without a catheter (TWOC) after HoLEP. The study objective was to determine the relationship between MOSES pulse modulation versus standard laser technology and short-term catheter reinsertion following failed TWOC. Materials and Methods The study included 487 patients who underwent HoLEP, using standard holmium laser settings (180 patients) or MOSES pulse modulation (255 patients), between August 2018 and February 2021. Catheter reinsertion defined as reinsertion following failed TWOC within 30 days of surgery. Association of pulse modulation with catheter reinsertion was examined using single and multivariable logistic regression models. Comparisons of pre and intraoperative characteristics between patients treated without and with pulse modulation were made using a Wilcoxon rank sum test for numeric characteristics or Fisher’s exact test for categorical characteristics. Results Short-term catheter reinsertion occurred in 14% (26/180) of the standard laser setting group as compared with 10% (24/252) of the pulse modulation group. There was no statistically significant association with short-term catheter reinsertion in single (unadjusted OR [standard settings vs. pulse modulation], 1.60; 95% CI, 0.80–2.91; p=0.12) or multivariable analysis adjusting for specimen weight and operative time (adjusted OR [standard settings vs. pulse modulation], 1.44; 95% CI, 0.77–2.68; p=0.25). Conclusions In this study, we found no association between post-HoLEP short-term catheter reinsertion following failed TWOC and MOSES pulse modulation. Although MOSES pulse modulation offers several well-documented advantages, catheter reinsertion events appear to be attributable to other factors.

Partial versus radical nephrectomy in clinical T2 renal masses. Int J Urol 2021; 28:1149-1154. [PMID: 34382267 DOI: 10.1111/iju.14664] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 07/14/2021] [Indexed: 12/30/2022]
Abstract
OBJECTIVE To report perioperative, renal functional and oncologic outcomes for patients undergoing partial or radical nephrectomy for cT2 renal masses. METHODS Retrospective review of patients who underwent partial (n = 72) or radical nephrectomy (n = 379) for cT2 renal masses from 2000 to 2016. After propensity adjustment using inverse probability weighting, the following were compared by surgery (partial or radical nephrectomy): complications, renal function measured by estimated glomerular filtration rate as continuous and as <60 mL/min/1.73 m2 at 1 and 3 years postoperatively and overall, metastases-free survival and cancer-specific survival in patients with renal cell carcinoma. RESULTS After propensity adjustment, clinical and radiographic features were well-balanced between groups. Overall and severe complications were more common for partial compared with radical nephrectomy, although not statistically significant (19 vs 13%, P = 0.14 and 4 vs 2%, P = 0.3, respectively). Estimated glomerular filtration rate change at 1 and 3 years was more pronounced in radical compared with partial nephrectomy (median -16 vs -5 and -14 vs -2, respectively, P < 0.001). A greater proportion of radical nephrectomy patients had an estimated glomerular filtration rate <60 at 1 and 3 years (55 vs 17% and 48 vs 17%, respectively, P < 0.01). In renal cell carcinoma patients, overall, metastases-free and cancer-specific survival were not significantly different between groups (median survivor follow up 7.1 years, interquartile range 3.6-11.4). CONCLUSIONS Partial nephrectomy appears to be a relatively safe and a potentially effective treatment for cT2 renal masses, conferring better renal functional preservation compared with radical nephrectomy. These data support continued use of partial nephrectomy for renal masses >7 cm in appropriately selected patients.

Cost-effectiveness of Retrograde Intrarenal Surgery, Standard and Mini Percutaneous Nephrolithotomy, and Shock Wave Lithotripsy for the Management of 1-2cm Renal Stones. Urology 2021; 156:71-77. [PMID: 34274389 DOI: 10.1016/j.urology.2021.06.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 06/01/2021] [Accepted: 06/28/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To perform a cost-effectiveness evaluation comparing the management options for mid-size (1-2cm) renal stones including percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), and shockwave lithotripsy (SWL). METHODS A Markov model was created to compare cost-effectiveness of PCNL, mini-PCNL, RIRS, and SWL for 1-2cm lower pole (index patient 1) and PCNL, RIRS, and SWL for 1-2 cm non-lower pole (index patient 2) renal stones. A literature review provided stone free, complication, retreatment, secondary procedure rates, and quality adjusted life years (QALYs). Medicare costs were used. The incremental cost-effectiveness ratio (ICER) was compared with a willingness-to-pay(WTP) threshold of $100,000/QALY. One-way and probabilistic sensitivity analyses were performed. RESULTS At 3 years, costs for index patient 1 were $10,290(PCNL), $10,109(mini-PCNL), $5,930(RIRS), and $10,916(SWL). Mini-PCNL resulted in the highest QALYs(2.953) followed by PCNL(2.951), RIRS(2.946), and SWL(2.943). This translated to RIRS being most cost-effective followed by mini-PCNL(ICER $624,075/QALY) and PCNL(ICER $946,464/QALY). SWL was dominated with higher costs and lower effectiveness. For index patient 2, RIRS dominated both PCNL and SWL. For index patient 1: mini-PCNL and PCNL became cost effective if cost ≤$5,940 and ≤$5,390, respectively. SWL became cost-effective with SFR ≥75% or cost ≤$1,236. On probabilistic sensitivity analysis, the most cost-effective strategy was RIRS in 97%, mini-PCNL in 2%, PCNL in 1%, and SWL in 0% of simulations. CONCLUSION For 1-2cm renal stones, RIRS is most cost-effective. However, mini and standard PCNL could become cost-effective at lower costs, particularly for lower pole stones.

Abstract
Background: Decidual reaction bladder endometriosis (DRBE) is exceedingly rare with few reported cases in the literature. It presents as a bladder mass during pregnancy, and may be accompanied by lower urinary tract symptoms. Histologic diagnosis is necessary to rule out primary bladder malignancy. We present a case of a bladder tumor identified during pregnancy. The mass was managed endoscopically and found to be DRBE, a rare benign entity. Case Presentation: We present a 31 year old 15 weeks pregnant nonsmoker woman with a rapidly enlarging bladder mass concerning for primary bladder malignancy. Mass confirmed on formal renal/bladder ultrasound and in-office cystoscopy. After informed consent was obtained, the patient was taken to the operating room. A 5.5 cm bladder mass, with an atypical nodular appearance and minor calcifications, was identified. Transurethral resection of the mass was performed. Final pathology report showed florid endometriosis with stromal decidualization. Final diagnosis: pregnancy induced vesical decidualized endometriosis simulating a bladder tumor. Patient continued routine obstetrics follow-up, and has experienced no pregnancy-related complications. Three months after delivery the patient will follow up with outside urology provider for cystoscopy, and subsequent surgical management should it be necessary. Conclusion: DRBE is a rare benign bladder mass that presents in pregnancy. It can grow rapidly raising concern for an aggressive primary bladder malignancy. Any bladder mass identified in pregnancy should undergo early, appropriate work-up given the potential risk for bladder cancer. After diagnosis, DRBE is most often managed conservatively. After delivery, should the patient experience ongoing urinary symptoms, medical and surgical treatment options are available. Overall, DRBE is considered rare, but should be considered in the differential diagnosis for any bladder mass presenting during pregnancy.

Endoscopic Management of Iatrogenic Ureteral Injury: A Case Report and Review of the Literature. J Endourol Case Rep 2020; 5:142-144.

Abstract
Background: Iatrogenic ureteral injury represents an uncommon, but significant, complication of gynecologic surgery. Endoscopy has typically played little to no role in the treatment of these injuries, which are traditionally managed with re-exploration or delayed repair. Delayed repair with temporary urinary diversion exposes the patient to significant morbidity. We present a case in which iatrogenic ureteral injury is managed definitively with endoscopy alone. Case Presentation: We present a 32-year-old female who developed a delayed postpartum hemorrhage following cesarean section, necessitating emergent hysterectomy. Postoperatively, there was concern for right ureteral injury. A computed tomography (CT) urogram was obtained showing right-sided hydronephrosis, but no obvious ureteral injury. After developing right flank pain, the patient was taken to the operating room for further evaluation. On semirigid ureteroscopy, a suture was identified within the lumen of the ureter and incised with the holmium laser, effectively treating the obstruction. At a 10-week follow-up, a renal ultrasound showed no hydronephrosis. At 8 months, the patient reports she is doing well with no flank pain. Conclusion: We present, to the best of our knowledge, the first published report in the United States of an iatrogenic ureteral ligation managed effectively in an acute postoperative setting with endoscopic holmium laser release, without balloon dilation, sparing the patient from delayed surgical intervention and the potentially associated morbidity. It is our belief that an initial retrograde pyelogram followed by a ureteroscopic evaluation should be performed as this allows for proper characterization of the injury, and may allow one to attempt definitive endoscopic management.

Robot-assisted partial cystectomy with intraoperative frozen section examination: Evolution and evaluation of a novel technique. Investig Clin Urol 2016; 57:221-8. [PMID: 27195322 PMCID: PMC4869563 DOI: 10.4111/icu.2016.57.3.221] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Accepted: 04/16/2016] [Indexed: 12/03/2022] Open
Abstract
Purpose To describe a novel modification to robot-assisted partial cystectomy (RAPC) that allows for intraoperative surgical margin assessment by bimanual-examination and frozen-section analysis. Materials and Methods A total of 7 patients underwent RAPC at a single tertiary-care institution between 2008 and 2013. The technique evolved over the study-period and permitted real-time intraoperative surgical margin evaluation in the last 5 patients via bimanual-examination and frozen-section analysis, utilizing the GelPOINT platform (a hand-assist device). The GelPOINT platform was placed through a 4- to 5-cm vertical supraumbilical incision and allowed for rapid retrieval of the bladder specimen without compromising the pneumoperitoneum or prolonging the operative time. Perioperative, oncological and functional outcomes were evaluated; all patients had a minimum 12-month follow-up. At the time of last follow-up, a cross-sectional survey of patients was performed to evaluate regret/satisfaction utilizing validated questionnaires. Results The mean age was 72.5 years; 71.4% of the patients were men (n=5). All patients underwent RAPC for a malignant indication. The mean operative and console times were 291 and 217 minutes, respectively. No patient had a positive surgical margin. Mean length-of-stay was 1.7 days. At a median follow-up of 38.9 months, 1 patient experienced a local recurrence 6 months postsurgery. The only mortality was secondary to Lewy-body disease, in the same patient, 1 year postoperatively. Patient assessment of regret and satisfaction indicated 0% regret and 0% dissatisfaction. Conclusions The 'modified' technique of RAPC is technically feasible, safe, and reproducible; further, RAPC leads to favorable oncological, functional and quality-of-life outcomes in patients eligible for partial cystectomy.

Abstract
INTRODUCTION To develop a nomogram to predict lymph node invasion (LNI) in the contemporary North American patient treated with robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS We included 2,007 patients treated with RARP and pelvic lymph node dissection (PLND) at a single institution between 2008 and 2012. D'Amico low risk patients underwent an obturator and hypogastric PLND, while extended PLND was reserved for intermediate/high risk patients. Logistic regression analysis tested the relationship between LNI and all available predictors. Independent predictors of LNI were used to develop a novel nomogram. Discrimination, calibration and decision-curve analysis were used to analyze the performance of our novel nomogram, and compare it to open radical prostatectomy (ORP)-based models, namely the Godoy nomogram. RESULTS Overall, 5.3% of our patients harbored LNI. Median number of lymph nodes removed was 6.0 (interquartile range: 4-11). The most parsimonious multivariable model to predict LNI consisted of the following independent predictors: PSA value, clinical stage, and primary and secondary Gleason scores (all p ≤ 0.02). The discrimination of our novel model was 86.2%, and its calibration was virtually optimal. Using a 2% nomogram cut off, 58% of patients would be spared PLND, while missing only 9.4% of individuals with LNI. The novel nomogram compared favorably to the Godoy nomogram, when discrimination, calibration and net-benefit were used as benchmarks. CONCLUSIONS Approximately 5% of contemporary North American patients harbor LNI at RARP. Our novel nomogram can accurately identify these patients, and this may help to improve patient selection, and avoid unnecessary PLND in the majority of patients.

Abstract
PURPOSE To examine the potential relationship between androgen deprivation therapy and other-cause mortality (OCM) in patients with prostate cancer treated with medical primary-androgen deprivation therapy, prostatectomy, or radiation. METHODS A total of 137,524 patients with non-metastatic PCa treated between 1995 and 2009 within the Surveillance Epidemiology and End Results Medicare-linked database were included. Cox-regression analysis tested the association of ADT with OCM. A 40-item comorbidity score was used for adjustment. RESULTS Overall, 9.3% of patients harbored stage III-IV disease, and 57.7% of patients received ADT. The mean duration of ADT exposure was 22.9 months (median: 9.1; IQR: 2.8-31.5). Mean and median follow-up were 66.9, and 60.4 months, respectively. At 10 years, overall-OCM rate was 36.5%; it was 30.6% in patients treated without ADT vs. 40.1% in patients treated with ADT (p < 0.001). In multivariable-analysis, ADT was associated with an increased risk of OCM (Hazard-ratio [HR]: 1.11, 95% Confidence-interval [95% CI]: 1.08-1.13). Patients with no comorbidity (10-year OCM excess risk: 9%) were more subject to harm from ADT than patients with high comorbidity (10-year OCM excess risk: 4.7%). CONCLUSIONS In patients with PCa, treatment with medical ADT may increase the risk of mortality due to causes other than PCa. Whether this is a simple association or a cause-effect relationship is unknown and warrants further study in prospective studies.

Abstract
INTRODUCTION We examine the incidence and predictors of readmission after major urologic cancer surgery using a national, prospective-maintained database specifically developed to assess quality of surgical care. MATERIALS AND METHODS Patients undergoing major urologic cancer surgery (radical prostatectomy [RP], radical nephrectomy [RNx], partial nephrectomy [PNx]), radical cystectomy [RC]) in 2011 were identified using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) using Current Procedural Terminology (CPT) codes. Those readmitted within 30 days after surgery were identified. Multivariable logistic regression models examined the association between patient characteristics and the odds of readmission. RESULTS Overall, we identified 5356 RP, 1301 RNx, 918 PNx and 623 RC patients, of which 206 (3.8%), 533 (6.8%), 348 (6.3%) and 129 (20.7%) were readmitted within 30 days respectively. Independent predictors of readmission for RP included age (Odds Ratio [OR]: 1.02, p = 0.02), American Society of Anesthesiology (ASA) score 3-5 (versus 1-2, OR: 1.35, p = 0.04), smoking status (OR: 1.53, p = 0.04), and the occurrence of wound complications (OR: 9.31, p < 0.001), thromboembolic (OR: 14.7, p < 0.001), and renal failure (OR: 1.62, p = 0.01) complications during the index hospitalization. For RC patients, the only predictor of readmission was age (OR: 0.98, p = 0.04). Predictors of readmission for RNx included higher ASA score (OR: 1.77, p = 0.03), and the presence of any complications during the index hospitalization (OR: 2.21, p = 0.03). CONCLUSIONS Several patient characteristics have a significant impact on the risk of 30 day readmission after major urologic cancer surgery. Our data suggests that improving prevention and management of complications during the index hospitalization may lead to a substantial decrease in readmission rates.

Abstract
We aimed to evaluate the role of robot-assisted radical prostatectomy (RARP) in the management of high-risk prostate cancer (PCa), with a focus on oncological, functional and perioperative outcomes. Further, we also aimed to briefly describe our novel modification to conventional RARP that allows immediate organ retrieval and examination for intra-operative surgical margin assessment. A literature search of PubMed was performed for articles on the management of high-risk PCa. Papers written in English and concerning clinical outcomes following RARP for locally advanced and high-risk PCa were selected. Outcomes data from our own center were also included. A total of 10 contemporary series were evaluated. Biopsy Gleason score ≥ 8 was the most common cause for classification of patients into the high-risk PCa group. Biochemical failure rate, in the few series that looked at long-term follow-up, varied from 9% to 26% at 1 year. The positive surgical margin rate varied from 12% to 53.3%. Urinary continence rates varied from 78% to 92% at 1 year. The overall complication rates varied from 2.4% to 30%, with anastomotic leak and lymphocele being the most common complications. Long-term data on oncological control following RARP in high-risk patients is lacking. Short-term oncological outcomes and functional outcomes are equivalent to open radical prostatectomy (RP). Safety outcomes are better in patients undergoing RARP when compared with open RP. Improved tools for predicting the presence of organ-confined disease (OCD) are available. High-risk patients with OCD would be ideal candidates for RARP and would benefit most from surgery alone.

Abstract
Metabolic syndrome has been implicated in the pathogenesis of uric acid stones. Although not completely understood, its role is supported by many studies demonstrating increased prevalence of uric acid stones in patients with metabolic syndrome and in particular insulin resistance, a major component of metabolic syndrome. This review presents epidemiologic studies demonstrating the association between metabolic syndrome and nephrolithiasis in general as well as the relationship between insulin resistance and uric acid stone formation, in particular. We also review studies that explore the pathophysiologic relationship between insulin resistance and uric acid nephrolithiasis.
