A comparison of clinical outcomes of operating room versus office-based ureteral stenting with the novel use of nitrous oxide sedation
To examine the safety and effectiveness of placing ureteral stents in an office-based setting versus in the operating room.
Evaluation of asymptomatic microscopic hematuria by renal ultrasound to detect upper tract malignancy: a 20-year experience in a community hospital
To evaluate the sensitivity of ultrasound imaging in detecting upper urinary tract malignancy in patients with asymptomatic microscopic hematuria (AMH) in an outpatient community setting.
Domain Comparison Between 6 Validated Questionnaires Administered to Women with Urinary Incontinence
To compare patients’ questionnaire-reported UI symptoms to determine which have the best concordance.
Performance of a Natural Language Processing Method to Extract Stone Composition from the Electronic Health Record
To demonstrate the utility of a natural language processing (NLP) algorithm for mining kidney stone composition in a large-scale electronic health records (EHR) repository.
to define computed tomography (CT) predictors of residual fragments after retrograde intrarenal surgery (RIRS) for kidney stones up to 20 mm in patients never submitted to surgical procedures for stone removal.
Nocturia is a bothersome, multifactorial condition with many underlying causes and contributing factors. Nocturnal polyuria (NP; overproduction of urine at night) is a frequent component. The prevalence of nocturia increases with age; specific estimates of prevalence are influenced by frequency thresholds used to define it. There is a tendency toward higher prevalence in young women than young men, which is reversed in later life.The association between frequency of nocturnal voiding and sleep disruption is well-documented.
Use of a Novel Articulating Laparoscopic Needle Driver for Partial nephrectomy: an initial experience
To demonstrate the clinical feasibility of an articulated laparoscopic needle driver to assist in the performance of laparoscopic PN (LPN). Previous studies have demonstrated under-utilization of minimally invasive techniques for patients undergoing partial nephrectomy (PN).
Nerves in the areas posterior to the prostate base contribute to erectile function: An intraoperative electrical stimulation assessment
To confirm the distribution of functional nerves involved in erectile function at the posterior of the prostate base, intraoperative nerve stimulation was performed during robot-assisted radical prostatectomy (RARP)
To evaluate the impact of frailty on adverse perioperative outcomes in patients treated with radical cystectomy for bladder cancer.
Upper Tract Urothelial Carcinoma grade prediction based on the ureteroscopic appearance: caution should be taken
To investigate the diagnostic accuracy, inter-rater and intra-rater agreement of grade predictions based on the visual appearance of papillary upper tract urothelial carcinoma (UTUC) during digital ureteroscopy.
Lynch Syndrome (LS) entails a defective DNA mismatch repair system, which is the post-replicative proofreading and editing system, ensuring our genome's integrity. LS predisposes to several cancers, most commonly colorectal and endometrial cancers. LS occurs in approximately 1 in 250–1,000 people.LS is associated with urological malignancies with upper tract urothelial carcinoma the most common, although still clinically underestimated. Other urologic malignancies possibly associated with LS include bladder, prostate, testis, and renal cell carcinoma.
Bochdalek hernia (BH) is a postero-lateral diaphragmatic congenital defect. Although most commonly diagnosed at birth, 0.17-6% of cases can also be seen in adults.A third of the cases may contain abdominal organs like small bowel, kidney or spleen.In our literature search we only found 3 reported cases of urinary obstruction secondary to herniation of the renal pelvis through a BH. Here we describe a rare case of upper urinary tract obstruction caused by a BH successfully treated by laparoscopic surgery in our center.
Lesions of the skin and soft tissues of the penis and scrotum may be confusing in urological practice, since rare differential diagnoses can be challenging to providers with limited dermatological experience. Hidradenocarcinoma is one of such diagnoses, a rare and aggressive malignant tumor originating from sweat glands.A 61 year-old man presented with a nodule in the penoscrotal region which had appeared 1 year before consultation. He had no history of penile lesions, sexually transmitted diseases or other complaints.
“A National Study Demonstrating the Need for Improved Frailty Indices for Preoperative Risk Assessment of Common Urologic Procedures”
To compare the associations between frailty indices and postoperative complications among older adults undergoing common urologic procedures. Frailty is known to be strongly associated with poor postoperative complications; however, the optimal way to measure frailty remains unknown.
Intravesical Electromotive Botulinum Toxin Type A (Dysport®) Administration in Children with Myelomeningocele
Electromotive drug administration (EMDA) presents a minimally-invasive method of intravesical instillation of therapeutic agents without the need for general anesthesia 1. It employs a combination of iontophoresis, electrophoresis, and electroporation to deliver drugs into deep tissue layers using an electrical current created between two electrodes 2. This video shows feasibility of botulinum toxin type A (BoNTA) EMDA in myelomeningocele (MMC) children with urinary incontinence secondary to neuropathic detrusor overactivity.
Evaluation of implementation outcomes after initiation of a shared decision-making program for men with prostate cancer
To evaluate barriers to implementation of patient decision aids (PDAs) issued in an electronic medical record (EMR). We undertook an implementation outcomes analysis focused on what proportion of men eligible for the PDA received it (penetration), and of the men who received it, how many used it as intended (fidelity). We also evaluated various patient centered outcomes related to decision making.
Laparoendoscopic single-site surgery (LESS) was developed to minimize the morbidity associated with laparoscopic surgery. Application of robotics in urologic surgery has been widely adopted given the advantages it provides over standard laparoscopy including three-dimensional vision, improved ergonomics and enhanced precision and dexterity. The real benefit of robotic LESS is still unbalanced by the limitations of this approach and the sole applicability by highly skilled surgeons. The ideal robotic platform for single port surgery should have the possibility of being deployed through a single access site restoring intra-corporeal triangulation for precise instrument maneuvers.
Bladder Hydrodistention Does Not Result In a Significant Change In Bladder Capacity For Interstitial Cystitis/Bladder Pain Syndrome Patients
To assess the impact of multiple (two or more) bladder hydrodistentions (HODs) on anesthetic BC in a large cohort of IC/BPS patients. Urinary bladder hydrodistention (HOD) under anesthesia is a third line therapeutic approach used to treat patients with interstitial cystitis/bladder pain syndrome (IC/BPS). There is some concern that performing multiple therapeutic HODs may be contraindicated due to the potential for contributing to a diminished bladder capacity (BC) over time.
Vaporization of Prostate by 160W GreenLight Laser on Postoperative Erectile Function – A Single center report
To evaluate the impact of photoselective vaporization of the prostate (PVP) on erectile function (EF) utilizing a 160W GreenLight laser system with up to 36 months of follow-up in men with lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH).
