Single Port Modified Partial Nephrectomy: Novel Simultaneous Access to Peritoneal and Retroperitoneal Partial Nephrectomy, Initial Clinical Experience.

Introduction and Objective: Since its Food and Drug Administration (FDA) approval in 2018, Intuitive Surgical DaVinci single port (SP) robotic platform has been an effectively used technology for multiple urologic procedures. The purpose of this study is to share our early intraoperative and perioperative outcomes and potential benefits for performing a lower anterior access (LAA) incision for SP robot-assisted partial nephrectomy (SP-RAPN). The LAA incision enables performing a trans- or retroperitoneal (RP) approach through the same incision and eases the transition to a RP approach. Methods: This study is a prospective review of 78 SP-RAPN cases between March 2021 and January 2023 by an experienced robotic surgeon. A single 2-3 cm oblique incision parallel to the external oblique muscle, one-third of the distance between the iliac crest and umbilicus, was used to insert the multichannel port to perform the RAPN. We extracted intra- and perioperative data of these patients to share the outcomes of this approach. Results: SP-RAPN was effectively completed in 78 patients (38 females and 40 males) without conversion to open or laparoscopic techniques. The mean age was 61.2 ± 12.1 years. The mean tumor size was 3.0 ± 1.2 cm, 43 were right-sided masses, and 35 were left sided. The R.E.N.A.L Nephrometry score ranged from (4-11) with an average of 7.0 ± 1.9. Average operating room time was 90.5 ± 24.6 minutes, estimated blood loss was 88.3 ± 134 mL, and length of stay of 1.07 ± 0.7 days. Of the 78 cases, 40 required clamping of the renal artery with average warm ischemia time of 19.4 ± 6.7 minutes in patients who underwent clamping. No complications in all of 78 patients. Conclusions: This study demonstrates the feasibility and reproducibility of SP-RAPN using a LAA incision. This incision provides a standardized approach for surgeons to transition to the RP approach using the SP platform.

Surgical Technique and Perioperative Outcomes Following Single-Port Robotic Adrenalectomy: A Single Institutional Experience.

Objective: To describe a single institution's experience with single-port robotic adrenalectomy (SP-RA) and report perioperative outcomes. Materials and Methods: This is a retrospective, single-center study of adult patients who underwent SP-RA between January 2019 and April 2022 by a single surgeon using an IRB-approved institutional database. Patient demographics, perioperative data, surgical pathology, and postoperative outcomes were assessed. Results: Nineteen patients were identified who underwent SP-RA by a single surgeon over the period reviewed. One patient underwent bilateral SP-RA for bilateral adrenal masses, totaling 20 SP-RA procedures performed. Mean operative time was 80.7 ± 22.9 minutes and mean length of stay was 33.1 ± 27.9 hours. Two minor complications (Clavien-Dindo

Hemorrhagic cystitis: a review of the literature and treatment options.

INTRODUCTION: Hemorrhagic cystitis (HC) is a morbid condition for patients and can be challenging for urologists to manage. There are many potential contributing etiologies and the severity of bleeding can be variable. It is important to consider each clinical scenario when formulating management strategies in order to provide the highest quality of care to patients. We provide a review of the literature including diagnosis and treatment options. MATERIALS AND METHODS: We performed a literature search on PubMed using the following keywords: hemorrhagic cystitis, cystitis, gross hematuria, intractable hematuria. We considered all available published articles with no specific inclusion or exclusion criteria for the purposes of this review. RESULTS: We reviewed a total of 41 articles and identified a broad differential diagnosis for intractable hemorrhagic cystitis including infection, chemical exposure, malignancy, nephropathy, trauma, radiation therapy, and idiopathic etiology. Depending on the severity of bleeding, many treatments have been described. These range from conservative strategies (bladder fulguration and continuous irrigation) to more extreme and morbid therapies (intravesical instillations, embolization, and urinary diversion). CONCLUSION: Hemorrhagic cystitis is a relatively common and can be a difficult condition to manage for urologists. It is important to understand the etiology and available treatments options in order to best treat our patients. We provide a comprehensive and thorough review of the literature and propose a stepwise treatment approach.

Holmium Laser Enucleation of the Prostate Following Previous Prostatic Urethral Lift.

Purpose: To determine the feasibility and operative challenges of holmium laser enucleation of the prostate (HoLEP) in patients with previous prostatic urethral lift (PUL) procedure. Materials and Methods: A retrospective review was performed on files of all patients that underwent HoLEP at our institution between 2013 and 2021. Seven hundred ninety-three consecutive HoLEP cases were identified. Data collected included demographics, the time elapsed since previous PUL, number of PUL implants, preoperative prostate size, intraoperative complications/challenges, and postoperative follow-up. Results: Twenty-two men with a mean preoperative prostate size of 90 g (range 32-180 g) underwent HoLEP at a median of 14.4 months (range 2.8-48) after PUL. 63.6% (14/22) of cases involved prostates with preoperative sizes ≥80 g. Three cases involved PUL implant jamming of morcellator blades, which required replacing the blades. Fifteen cases (68.2%) required using a grasper or a basket device to remove free PUL implants or adenoma parts with PUL implants embedded in them. One patient needed a second procedure to remove a relatively large piece of calcified adenoma. Nonpost-PUL HoLEP was more time efficient than post-PUL HoLEP (0.77 vs 0.55 mL/minute respectively). There was no difference in functional outcome between post-PUL and nonpost-PUL HoLEP cases. Conclusions: While HoLEP can be performed safely and effectively in the PUL failure population, unique challenges arise. PUL implants may distort prostate anatomy, jam morcellator blades, and may be encountered in aberrant locations. Patients with borderline indications for PUL should be aware of the possibility of performing HoLEP in case of PUL failure.

Vesicoureteral Reflux in Adults with Urinary Tract Infections: Is There a Role for Treatment?

PURPOSE OF REVIEW: Urinary tract infections (UTI) place a significant burden on individual patients and the healthcare system as a whole. Vesicoureteral reflux (VUR) is a risk factor for UTIs and is the focus of much research in the pediatric field due to the opportunity for early intervention and prevention of long-term sequelae. However, VUR in the adult population is not well studied and can present different treatment challenges. The goal of this review article is to discuss the role VUR plays in UTIs in the adult population with a specific focus on complications and treatment. RECENT FINDINGS: The true prevalence of VUR in the adult population remains unknown, and urologists need to maintain an index of suspicion for VUR when evaluating adult patients with recurrent pyelonephritis or complicated UTIs. A number of case series and smaller retrospective studies have documented successful endoscopic treatment of adult VUR patients with recurrent pyelonephritis. Ureteral reimplantation remains an option for adult patients who are refractory to endoscopic treatment of VUR. The current treatments and recommendations for VUR in adults have been extrapolated from the pediatric population due to the scarcity of research. VUR is uncommon in the adult population and requires a high index of suspicion by the clinician. Accurate diagnosis and treatment of VUR can relieve patients from recurrent infections, repetitive antibiotic use, and the risk of hospitalization.

Retrograde Ureteroscopic Management of Large Renal Calculi: A Single Institutional Experience and Concise Literature Review.

INTRODUCTION: Advances in flexible ureteroscope design and accessory instrumentation have allowed for more challenging cases to be treated ureteroscopically. Here, we evaluate our experience with ureteroscopy (URS) for the management of large renal calculi (≥2 cm) and provide a concise review of recent reports. METHODS: A retrospective review was undertaken of all URS cases between 2004 and 2014 performed by the endourologic team at a single academic tertiary care institution. We identified patients with at least one stone ≥2 cm managed with retrograde URS. Stone size was defined as the largest linear diameter of the index stone. Small diameter flexible ureteroscopes were used primarily with holmium laser. Patient demographics, intraoperative data, and postoperative outcomes were evaluated. RESULTS: We evaluated 167 consecutive patients who underwent URS for large renal stones ≥2 cm. The initial reason for choosing URS included patient preference (29.5%), failure of other therapies (8.2%), anatomic considerations/body habitus (30.3%), and comorbidities (28.8%). Mean patient age was 55.5 years (22-84). The mean stone size was 2.75 cm with mean number of procedures per patient of 1.65 (1-6). The single session stone-free rate was 57.1%, two-stage procedure stone-free rate was 90.2% and three-stage stone-free rate was 94.0%. Access sheaths were used in 47% of patients. An association was identified between stone size and patient outcomes; smaller stones correlated with decreased number of procedures. Postoperative complications were minor. CONCLUSIONS: Single or multi-stage retrograde ureteroscopic lithotripsy is a safe and effective mode of surgical management of large renal calculi. Total stone burden is a reliable predictor of the need for a staged procedure and of stone-free rate.

Four-corner arthrodesis with a radiolucent locking dorsal circular plate: technique and outcomes.

BACKGROUND: Scaphoid excision and four-corner arthrodesis (FCA) is an acceptable motion sparing procedure used to treat wrist arthritis. Recently, a locking dorsal circular plate composed of polyether-ether-ketone has been introduced (Xpode®; TriMed Inc.). The purpose of this study is to assess the efficacy of this specific plate design with regard to FCA. METHODS: A retrospective chart review of all patients who underwent FCA with an Xpode® between January 1, 2008 and December 31, 2012 was conducted. Patients were contacted and asked to return to clinic for clinical and radiographic follow-up. Patient demographics, range of motion, grip strength, and complications were collected from medical records. Patients completed a patient-rated wrist evaluation (PRWE). A paired t test was used to compare means, and p values <0.05 were considered statistically significant. RESULTS: Twenty-six procedures (24 patients) were identified. One patient required full wrist fusion following the initial procedure. Of the 25 remaining wrists, arthrodesis was successfully achieved in 20 (80 %). Eleven patients (13 wrists, 52 %) returned to clinic for an average follow-up of 28 months. Mean wrist extension improved from 30 to 47°, and flexion decreased from 33 to 23°. Average grip strength was 77 % of the uninjured side. The mean PRWE scores for pain and function were 19.7 and 17.1, respectively. Five patients underwent additional operations (two hardware removals, two contracture releases, and one distal radial ulnar joint arthroplasty). CONCLUSIONS: FCA with the Xpode® yielded reasonable results for pain and function and demonstrated a fusion rate of 80 %.
