Optimal interval for delayed retrieval surgery with reciprocating morcellators after enucleation of giant prostatic hyperplasia in holmium laser enucleation of the prostate.

Objective: The aim of this research was to evaluate the efficiency of reciprocating morcellation for removing giant benign prostatic hyperplasia during holmium laser enucleation of the prostate, investigate whether performing morcellation as a two-stage procedure improves tissue retrieval efficiency, and seek to determine the optimal interval between the two surgeries.

Methods: This study included nine cases of holmium laser enucleation of the prostate with an enucleated prostate weight exceeding 200 g, indicative of substantial prostate enlargement. Morcellation was performed on Day 0 (=4), Day 4 (=1), Day 6 (=1), and Day 7 (=3).

Cost-effectiveness analysis of minimally invasive surgical treatments for benign prostatic hyperplasia: implications for Japan's public healthcare system.

Aims: Benign prostatic hyperplasia (BPH) represents a significant public health issue in Japan. This study evaluated the lifetime cost-effectiveness of water vapor energy therapy (WAVE) versus prostatic urethral lift (PUL) for men with moderate-to-severe BPH from a public healthcare payer's perspective in Japan.

Materials And Methods: A decision analytic model compared WAVE to PUL among males in Japan.

Holmium laser enucleation of the prostate as a secondary surgery following prostatic urethral lift.

Introduction: Prostatic urethral lift is a treatment option for benign prostatic hyperplasia, yet information on surgeries following this procedure is scarce.

Case Presentation: A 71-year-old man with persistent urinary retention following prostatic urethral lift underwent a secondary holmium laser enucleation of the prostate. The morcellation procedure, complicated by the presence of implants from the previous surgery, broke the morcellator blade.

Computed Tomography Renal Volumetry Better Predicts Postoperative Donor Renal Function in Live Kidney Donor Transplantation than Renal Scintigraphy: A Comparative Study.

Introduction And Objectives: Both computed tomography (CT) and renal scintigraphy (RS) have been used to assess vascular anatomy, renal status, and split renal function (SRF). In this study, we used a recently developed software that facilitates renal volumetric evaluations to compare RS and automated CT volumetry for assessing residual renal function and, thus, estimating postoperative renal function after donor nephrectomy.

Methods: Fifty-one cases of donor nephrectomy were analyzed.

Leiomyoma of the Prostate Treated via Holmium Laser Enucleation: A Case Report and Literature Review.

Leiomyoma is a rare tumor that arises from mesenchymal cells, with few reported cases of treatment using holmium laser enucleation of the prostate. A 74-year-old man with dysuria had a mass near the bladder neck in magnetic resonance imaging; this entity was suspected to be a leiomyoma. The patient underwent holmium laser enucleation of the prostate and one lobe was removed.

Risk Factors for Intraoperative Hypothermia during Holmium Laser Enucleation of the Prostate.

Introduction: Holmium laser enucleation of the prostate (HoLEP) is considered a size-independent gold standard for benign prostatic hyperplasia (BPH), and there is no upper limit of prostate weight that can be treated. Tissue retrieval can be time-consuming in cases of significant prostatic enlargement, which may lead to intraoperative hypothermia. As there are few studies on perioperative hypothermia in HoLEP, we conducted a retrospective study of patients who underwent HoLEP at our hospital.

Simplified approach to the medial internal iliac region using a uretero-hypogastric nerve fascia development procedure for extended pelvic lymph node dissection during robot-assisted radical prostatectomy for high-risk prostate cancer.

Introduction: Although several clinical guidelines for prostate cancer (PC) recommend extended pelvic lymph node dissection (ePLND) during radical prostatectomy for high-risk cases, there are several issues to consider, including certain technical aspects. A simplified approach to the medial internal iliac region and paravesical arteries has not been established. The uretero-hypogastric nerve fascia (UHF) envelopes the ureter, hypogastric nerve, and pelvic autonomic nerves.

Peritoneal invasion of prostate cancer directly confirmed during robot-assisted radical prostatectomy.

Introduction: Several studies have been published on direct rectal invasion in patients with advanced metastatic prostate cancer, but few have directly confirmed intraoperative invasion of prostate cancer into the peritoneum.

Case Presentation: We report the case of a 73-year-old man with prostate cancer who exhibited peritoneal invasion during robot-assisted radical prostatectomy. His prostate-specific antigen level fell to 0.

Long-term results after robot-assisted radical prostatectomy of a simplified inguinal hernia prevention technique without artificial substance use.

Introduction: Durable techniques that prevent postoperative inguinal hernia (IH) after robot-assisted radical prostatectomy (RARP) have not been established. This study evaluated the long-term efficacy of a postoperative IH prevention technique that uses no artificial agents to assess the characteristics of IH occurrence after introducing this technique.

Patients And Methods: We retrospectively analyzed 201 consecutive patients who underwent RARP at our institution between September 2011 and February 2014.

Japanese giant benign prostatic hyperplasia: Sibling cases.

Introduction: The pathophysiology of benign prostatic hyperplasia (BPH) remains incompletely understood but is likely multifactorial. Inflammation and metabolic factors may increase the risk of BPH. Several studies have evaluated the possible roles played by genetic factors.

Testicular metastasis from urothelial carcinoma of the bladder.

Introduction: Reports of urothelial carcinoma with testicular metastasis are limited and the etiology and prognosis remain unclear. We report a rare case of testicular metastasis derived from bladder urothelial carcinoma.

Case Presentation: A 68-year-old man presented with gross hematuria and urinary frequency.

Late-onset Hem-o-Lok® migration into the bladder after robot-assisted radical prostatectomy.

Introduction: Hem-o-Lok clips are widely used in robot-assisted radical prostatectomy because of their ease of application and secure clamping. Although there have been some reports of their migration into the urinary tract, this usually occurs a few months after robot-assisted radical prostatectomy. Late-onset cases of Hem-o-Lok clip migration, that is, after more than 1 year, are rare.

[A Case of Multiple Renal Carcinomas with Three Different Subtypes].

We report a case of dialysis kidney with multiple renal carcinomas in three locations. A 74-year-old man who had a 20-year history of dialysis, was admitted to our hospital complaining of sudden right lateral area pain. Computed tomography (CT) scan revealed hemorrhage from the right dialyzed renal subcapsule.

Prostate cancer featuring a unique progression pattern: A case of prominent direct perineal invasion without definite metastasis.

Locally advanced prostate cancer can extend into the pelvis, and can also invade the bladder and rectum. We encountered a patient with prostate cancer that exhibited severe local invasion, protruding into the perineum. Distant metastasis was absent, despite the large tumor size.

Positive urine culture under indwelling urethral catheterization is a risk factor for febrile complications after holmium laser enucleation of the prostate (HoLEP).

Objectives: To investigate the incidence of and risk factors for febrile complications (FCs) in patients undergoing holmium laser enucleation of the prostate (HoLEP).

Methods: This retrospective study enrolled 847 consecutive patients who underwent HoLEP in our hospital from June 2006 to December 2018. FCs were defined as a body temperature ≥38.

Optimizing first trocar access for robot-assisted radical prostatectomy: Optical trocar access through the upper abdominal quadrant using the Kii Fios First Entry trocar.

Objectives: A pre-equipped metal trocar is required to use as a camera trocar due to a specification change in the da Vinci X/Xi system (Intuitive Surgical). We observed slight slippage of a trocar placed by the open method. With optical trocar access (OTA), the initial trocar is viewed directly with a laparoscope during placement.

One-surgeon basketing technique for stone extraction during flexible ureteroscopy for urolithiasis: A comparison between novice and expert surgeons.

Objective: To determine the safety and efficacy of the one-surgeon basketing technique for stone extraction during flexible ureteroscopy when carried out by novice surgeons under instructor guidance.

Methods: We retrospectively compared perioperative results, complications and the "stone-free" rate (defined as ≤2 mm fragments on kidney-ureter-bladder imaging 1 month after flexible ureteroscopy) between experienced (group A, n = 50) and novice (group B, n = 50) surgeons using the one-surgeon basketing technique.

Results: Baseline patients' characteristics were similar between the two groups.

Impact of indocyanine green-guided extended pelvic lymph node dissection during robot-assisted radical prostatectomy.

Objectives: To evaluate the effectiveness of indocyanine green-guided extended pelvic lymph node dissection during robot-assisted radical prostatectomy for intermediate- to high-risk prostate cancer.

Materials And Methods: After institutional review board approval, between July 2017 and December 2018, we carried out 100 indocyanine green-guided extended pelvic lymph node dissections in patients with localized intermediate- and high-risk prostate cancer, using the Firefly (Novadaq Technologies, Mississauga, ON, Canada) and da Vinci Xi surgical system (Intuitive Surgical, Sunnyvale, CA, USA). Indocyanine green was injected transrectally using ultrasound sonography before each surgery.

The Use of Cumulative Sum Analysis to Derive Institutional and Surgeon-Specific Learning Curves for Robot-Assisted Radical Prostatectomy.

The cumulative sum (CUSUM) approach has been adopted to evaluate surgical competence in various contexts. The CUSUM method comprises sequential monitoring of cumulative differences from a target level in performance quality over time, allowing the detection of deviations from the target. We use the CUSUM method in this study to derive both institutional and surgeon-specific learning curves for robot-assisted radical prostatectomy (RARP).

[A Case of a Congenital Right External Iliac Vein Defect Found after Robot-Assisted Radical Prostatectomy].

Congenital external iliac vein defects are extremely rare. A 56-year-old man underwent robotic prostatectomy (RARP) without pelvic lymph node dissection (PLND) for localized low-risk prostate cancer. Intraoperative findings revealed a markedly dilated vein on the dorsal side of the pubic bone,which was difficult to preserve and was therefore clipped.

Renal cell carcinoma treatment during pregnancy: Histopathological findings suggestive of rapid tumor growth.

Introduction: Diagnosis of renal cell carcinoma during pregnancy is rare. We report a case of renal cell carcinoma during pregnancy with rapid growth.

Case Presentation: A 39-year-old woman presented to our hospital for treatment of renal tumor at 22 weeks gestation.

Renal Transplantation with Simultaneous Aortoiliac Reconstruction Using a Polytetrafluoroethylene Vascular Graft for Severe Atherosclerosis.

Studies on aortoiliac reconstruction for severe atherosclerosis with renal transplantation are limited. Here, we report a rare experience of the simultaneous reconstruction of the external iliac artery caused by severe atherosclerosis with polytetrafluoroethylene vascular graft and renal transplantation in a 55-year-old female; she was unable to undergo standard renal artery anastomosis to the right external iliac artery because of severe atherosclerosis, which would result in complete occlusion. Next, we directly anastomosed the donor renal artery to the polytetrafluoroethylene graft.

[Complications and Proposed Preventive Measure of Holumium Laser Enucleation of the Prostate during the Initial Phase at Our Hospital].

Clinical charts of 95 patients who underwent holmium laser enucleation of the prostate (HoLEP) between May 2012 and January 2016 were reviewed for complications and their causative factors, as well as treatment outcomes. Of 23 intraoperative complications and 3 cases of prolonged post prostatectomy incontinence, 23 incidents (89%) occurred within the initial 20 cases performed by each surgeon. The details of the intraoperative complications were : bladder injury, 6 (6.
