Item Comparison of Newly Optimized Moses Technology vs Standard Holmium: YAG for Endoscopic Laser Enucleation of the Prostate(Liebert, 2021-12) Nottingham, Charles U.; Large, Tim; Agarwal, Deepak K.; Rivera, Marcelino E.; Krambeck, Amy E.; Urology, School of MedicineIntroduction: The purpose of this study was to describe our initial experience of using a newly optimized Moses technology that is part of the second-generation Moses platform specifically designed for holmium laser enucleation of the prostate (M2-HoLEP) and compare it with patients undergoing HoLEP using standard holmium:YAG technology (S-HoLEP). Materials and Methods: We retrospectively collected data on patients who underwent M2-HoLEP and compared it with the last 50 patients in whom we performed S-HoLEP. Specifically, we compared preoperative symptom scores for lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), preoperative objective voiding metrics, as well as intraoperative characteristics, perioperative characteristics, postoperative complications, postoperative symptom scores for LUTS and ED, and postoperative objective voiding metrics. Additionally, we evaluated the ability for same-day discharge following surgery in the M2-HoLEP group. Results: We included 104 total patients for analysis. We compared the first 54 patients undergoing M2-HoLEP with 50 patients undergoing S-HoLEP. Both groups had similar age, body mass index, use of anticoagulation medication, LUTS and ED scores, and objective voiding metrics. Operations performed with M2-HoLEP had faster mean hemostasis time (8.7 vs 10.6 ± 6 minutes, p = 0.03) as well as hemostasis rate (0.13 vs 0.30 min/g, p = 0.01). Same-day discharge was achieved in 69.4% of patients in the M2-HoLEP group. Postoperatively, both groups also had similar and low rates of urinary retention and complications. At follow-up, both groups had similar symptom scores for LUTS and ED, as well as similar objective voiding metrics. Conclusions: The newly optimized Moses pulse modulation technology is safe and efficient for the treatment of benign prostate hyperplasia. Such technologic improvements in the laser have greatly enhanced the feasibility of same-day discharge of patients undergoing HoLEP.Item Correlating Patient Anxiety with Urinary Symptoms Before and After Holmium Laser Enucleation of the Prostate(Liebert, 2020) Nottingham, Charles U.; Agarwal, Deepak K.; Valadon, Crystal; Large, Tim; Rivera, Marcelino E.; Krambeck, Amy E.; Urology, School of MedicineIntroduction and Objective: Preoperative anxiety has been shown to correlate with certain urinary symptoms in patients with certain types of voiding dysfunction, particularly overactive bladder. The purpose of this study was to evaluate if patient-reported anxiety correlates with pathologic characteristics, voiding symptoms, and objective metrics of bladder emptying in male patients undergoing holmium laser enucleation of the prostate (HoLEP). Patients and Methods: We began collecting patient-reported anxiety scores (generalized anxiety disorder 7-item or GAD-7) in addition to patient-reported scores of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) starting in November 2018 for men with LUTS due to benign prostate hyperplasia (BPH). We retrospectively evaluated the relationship between preoperative GAD-7 score with preoperative age, body mass index (BMI), preoperative urine flow metrics, preoperative postvoid residual (PVR), and preoperative symptom scores for LUTS (American Urological Association, BPH impact index [BII], and Michigan incontinence symptom index [MISI]) and ED (sexual health inventory for men and male sexual health questionnaire for ejaculatory dysfunction [MSHQ-EjD]). We then compared preoperative GAD-7 score with enucleated prostate weight, postoperative GAD-7 scores, postoperative urine flow metrics, postoperative PVR, and postoperative symptom scores for LUTS and ED. Results: We included 139 patients for analysis. The preoperative GAD-7 score positively correlated with preoperative BII scores (rs = 0.202, p = 0.019), MISI total (rs = 0.260, p = 0.002), and MISI bother (rs = 0.345, p < 0.001) scores. Preoperative GAD-7 negatively correlated with preoperative MSHQ-EjD (rs = −0.191, p = 0.031). Following HoLEP, all four of these correlations disappear. The GAD-7 score did not correlate with age, BMI, preoperative urine flow metrics, preoperative PVR, or other preoperative LUTS and ED symptom scores. In addition, preoperative GAD-7 score showed no correlation with enucleated prostate weight, postoperative urine flow metrics, postoperative PVR, and postoperative LUTS and ED symptom scores. Conclusions: Higher preoperative anxiety correlated with more severe preoperative urinary LUTS, particularly incontinence symptoms, in patients undergoing HoLEP. Following HoLEP, these symptoms improve regardless of patient anxiety level.Item The role of prostate inflammation and fibrosis in lower urinary tract symptoms(APS, 2016-10) Bushman, Wade A.; Jerde, Travis J.; Department of Pharmacology and Toxicology, IU School of MedicineLower urinary tract symptoms (LUTS) in aging men are extremely common. They have historically been attributed to benign prostatic hyperplasia (BPH), enlargement of the prostate, and bladder outlet obstruction. However, recent studies have revealed acute and chronic inflammation to be highly associated with LUTS, correlated with prostatic enlargement, and implicated as a cause of prostatic fibrosis that contributes to bladder outlet obstruction. This review examines the evidence implicating inflammation and fibrosis in BPH/LUTS. It identifies potential mechanisms by which inflammation may drive nociceptive signaling as well as hyperplastic growth and fibrosis and identifies targets for pharmacological intervention. This is a promising area for research and development of novel therapies to prevent or more effectively treat LUTS in aging men.
