Reply to: Letter-to-the-editor: Understanding the popcorn effect during holmium laser lithotripsy for dusting
We thank the authors for their interest in our study. Our fundamental finding was that increasing the pulse frequency and the overall power led to significantly more fragmentation during popcorning. This was similar to what was also reported by Emiliani and colleagues.1 Moreover, we found that increasing the distance between the fiber tip and the stone decreased fragmentation. As noted, figure 2 showed that the percentage of submillimeter fragments when utilizing 40Hz and 80Hz at 0.5J was 67% and 73%, respectively.
Robotic Pyelolithotomy for the Intact Removal of a Complete Staghorn Calculus: A Feasible Approach Even After a Previous Open Pyelolithotomy
To describe the steps and technique of a robotic pyelolithotomy for complete removal of a left staghorn stone after a previous open pyelolithotomy.
To determine the most cost-effective approach to the management of distal ureteral stones in children given the potential for recurrent renal colic during a trial of passage versus potential stent discomfort and complications of ureteroscopy.
Acute kidney injury induced by pneumoperitoneum pressure via a mitochondrial injury-dependent mechanism in a rabbit model of different degrees of hydronephrosis
To clarify the effect of mitochondrial injury during laparoscopic surgery of the kidney in different degrees of hydronephrosis in rabbit model.
The relative efficacy and safety of mirabegron and onabotulinumtoxinA in patients with overactive bladder who have previously been managed with an antimuscarinic: A network meta-analysis
This study compared the efficacy and safety of mirabegron and onabotulinumtoxinA in the management of treatment-experienced patients with overactive bladder. The network meta-analysis was based on evidence from a systematic literature review of randomized controlled trials and a post-hoc analysis of treatment-experienced subpopulations from mirabegron studies. Nineteen trials described in 21 publications were included. Overall, compared to mirabegron, there was some evidence that onabotulinumtoxinA was associated with improved outcomes, including reductions in the number of micturitions in a 24-hour period, and the number of incontinence episodes.
Expanded Prostate Cancer Index Composite-26 (EPIC-26) Online: Validation of an Internet-Based Instrument for Assessment of Health-Related Quality of Life after Treatment for Localized Prostate Cancer
To test the validity of an Internet-based version of EPIC-26 versus the phone-based version. Most men will survive for years after treatment for localized prostate cancer (PCa) and may experience lasting treatment-related toxicities affecting health-related quality of life (HRQoL). The Expanded Prostate Cancer Index Composite (EPIC-26) is a validated instrument that measures HRQoL across 5 PCa-specific domains. Previously, EPIC-26 was administered via phone in a large multicenter clinical trial.
Testicular Volume Changes in Laparoscopic Staged Fowler-Stephens Orchiopexy: Studying the Impact of Testicular Vessel Division
To study the effect of testicular vessel division on testicular volume during laparoscopic staged Fowler Stephens orchiopexy (LSFSO).
To explore the use of neo-vaginal advancement flaps in the treatment of distal urethral strictures with description of the techniques and preliminary results in transwomen.
Distribution of Semen Parameters Among Adolescent Males Undergoing Fertility Preservation in a Multicenter International Cohort
To determine the distribution of semen parameters among adolescent and adult males presenting for fertility preservation.
To understand trends in pediatric cases performed during urology residency including intra-resident variability and cases performed relative to required minimums.
Downgrading of Grade Group After Radical Prostatectomy: Comparison of Multiparametric Magnetic Resonance Imaging Guided Fusion Biopsy and Standard 12-Core Biopsy
To analyze the factors associated with Grade group (GG) downgrading post-radical prostatectomy.
Consistencies and discrepancies between the expectations of urology trainees and the experience of practicing urologists
To compare the expectations of urology trainees with the experience of practicing urologists.
To examine trends in underrepresented minority (URM) representation in urology residency. Comparison is made between URM representation in urology residency and URM representation in other surgical fields as well as all medical fields. We hypothesized that percentage of URM in urology has been limited when compared to both surgical fields and all other fields.
A 53-year-old man presented to our hospital with right upper quadrant (RUQ) pain alongside nausea and vomiting. Physical examination revealed RUQ tenderness, Murphy sign, and fever. He otherwise had no significant past medical or surgical history. Subsequent abdominal ultrasound showed signs of cholecystitis and an incidental lobulated hypoechoic mass of the left kidney with heterogeneous echotexture and hypervascularity on Doppler. The patient had a cholecystectomy without complications during the postoperative period.
Cutaneous metastasis from renal cell carcinoma (RCC) is rare, typically involves the head and neck, and occurs in late stage disease, usually in the context of previously diagnosed and treated primary tumour, and after lymphatic spread.This patients’ initial presentation of clear cell RCC was a cutaneous lesion to the ipsilateral abdominal wall. The primary renal tumour was subsequently demonstrated on CT; this also showed no apparent lymph node involvement despite cutaneous metastatic disease. The patient underwent radical laparoscopic nephrectomy and biological therapy, but disease progression continued, and he passed away within 6 months of diagnosis.
A 66-year-old gentlemen with a history of recurrent urothelial carcinoma in situ treated with endoscopic resection and induction BCG developed a new renal mass on surveillance computerized tomography (CT) and was referred to our institution for surgery. Biopsy was performed and pathology showed BCG granuloma. The patient was clinically asymptomatic. No surgical intervention was required. This is a rare entity in those undergoing intravesical BCG therapy. To avoid unnecessary surgery, a careful patient history and judicious use of renal mass biopsy is critical.
To examine the relationship between phosphodiesterase 5 inhibitor drugs (PDE5i) and skin cancers in a large-scale study of Veterans.
To evaluate rates of guideline adherence and associations with voiding cystourethrogram result. The American Academy of Pediatrics guidelines recommend voiding cystourethrogram after abnormal renal ultrasound or two febrile urinary tract infections. It is unclear whether guideline adherence increases vesicoureteral reflux detection. Additionally, guidelines targeting children 2-24 months are often applied to other ages.
Medial renal ptosis is the abnormal mobility of the kidney towards or across the midline of the body. Historically, this phenomenon is evaluated by observing abnormal mobility in the lateral decubitus position during intravenous pyelography. Here, we present the first radiographic documentation of this anomaly on computed tomography on a 34-year-old female who experienced an intermittent abdominal bulge over her right upper quadrant. Nephropexy is the definitive treatment for symptomatic patients.
