TL;DR: A novel endoscope, Aihua (AH)-1 stone removal system (SRS), is recommended, and the structure and function to treat bladder stones are introduced and a jaw to grab and extract stone and lithotripsy tube is introduced.
Abstract: Purpose: To recommend a novel endoscope, Aihua (AH)-1 stone removal system (SRS), and introduce the structure and function to treat bladder stones. Materials: SRS is composed by illuminant and imaging component, continuous-flow component, a jaw to grab and extract stone, lithotripsy tube, handle, and sheath. The entire device is usually attached to a video camera to provide vision for the surgeon. During surgical procedure, first 26F SRS was inserted into bladder to search stone. Then, stone was grabbed and fixed using jaw, and lithotripsy was performed with holmium laser or pneumatic lithotripter through lithotripsy tube. Fragments could be extracted using jaw through sheath synchronously. If there were more residual small fragments, Ellik evacuator could be connected with sheath to wash out them. Finally, resectoscope was inserted in urethra to perform transurethral resection of the prostate (TURP). Between January 2008 and July 2010, 37 cases of bladder stone with benign prostatic hyperplasia ...

TL;DR: The aim of present study was to develop a safe and effective technique for clamp off laser-assisted laparoscopic (LLPN)/retroperitoneoscopic (LRPN), which was consecutively included in a prospective study to evaluate LLPN/LRPN.
Abstract: Introduction: Laparoscopic and retroperitoneoscopic partial nephrectomy are well-described techniques.1 Hemostasis is challenging during this procedures. Clamping of the renal vasculature is often necessary to allow for tumor removal in bloodless field. The consequent warm ischemia (WI) places significant time constraints on the surgeon.2 Although different ex vivo reports on laser-assisted partial nephrectomy using different types of lasers were published, there are a few available in vivo series that mostly described an open partial nephrectomy under cold ischemia.3–10 The aim of present study was to develop a safe and effective technique for clamp off laser-assisted laparoscopic (LLPN)/retroperitoneoscopic (LRPN). Patients and Methods: Eight patients (6 men, 2 women; age range, 32–88 years) were consecutively included in a prospective study to evaluate LLPN/LRPN. These were chosen (out of 28 patients) on the basis of T1-tumors of different sizes and kidney locations in patients with different ...

TL;DR: Laparoscopic pyeloplasty is a first-line option for the management of ureteropelvic junction obstruction and has a greater success rate than endopyelotomy, and is associated with a shorter and less intense convalescence than open surgical pyelplasty.
Abstract: Laparoscopic pyeloplasty is a first-line option for the management of ureteropelvic junction obstruction. It has a greater success rate than endopyelotomy, and is associated with a shorter and less intense convalescence than open surgical pyeloplasty. The technique is well established and reproducible, although the procedure is more difficult in certain situations such as after a prior pyeloplasty. Because laparoscopic suturing is required, it is considered an advanced laparoscopic procedure. Suturing devices can facilitate suturing, but they are not optimal for all repairs. The accompanying video shows the pre-, intra-, and postoperative considerations for laparoscopic pyeloplasty. No competing financial interests exist.

TL;DR: The technique of application of robotic bulldog clamps for hilar clamping using two different types of clamps is described and perioperative outcomes of the initial series of RAPN using robotic bull dog clamps are compared with laparoscopic bulldogClamps.
Abstract: Introduction: The need for a skilled assistant for hilar clamping has been considered a potential limitation of robot-assisted partial nephrectomy (RAPN).1,2 In this video, which has a runtime of 5 minutes and 15 seconds, we describe our technique of application of robotic bulldog clamps for hilar clamping using two different types of clamps. Perioperative outcomes of the initial series of RAPN using robotic bulldog clamps are also compared with RAPN using laparoscopic bulldog clamps. Materials and Methods: A total of 25 patients underwent RAPN using robotic bulldog clamps designed for application with the robotic Prograsp instrument. Robotic bulldog clamps were introduced and removed through the assistant trocar. The perioperative characteristics of 25 consecutive patients who underwent RAPN using robotic bulldog clamps were compared with preceding 25 consecutive patients using standard laparoscopic bulldog clamps. Results: All 25 patients underwent hilar clamping during RAPN using robotic bulld...

TL;DR: This video shows the key steps of creating the retroperitoneal space, the use of indigenous and commercial balloons, the utilization of different energy sources for dissection, the different techniques to control the renal hilum, the repair of an inferior vena cava injury, and the comparison between the Anderson-Hyne's and Foley's Y-V pyeloplasty.
Abstract: Introduction: Retroperitoneal laparoscopy for the kidney is a well-established approach to perform a variety of ablative and reconstructive procedures for different pathologies. This approach has several advantages, allowing direct posterior access to the kidney circumventing peritoneal cavity and a more immediate path to the renal hilum. In this video (running time of 15 min) the retroperitoneal laparoscopic approach is exhibited, including the creation of retroperitoneal space and the operative technique of various surgical procedures. Methods and Materials: We utilize portions of four different cases to illustrate the following: the key steps of creating the retroperitoneal space, the use of indigenous and commercial balloons, the utilization of different energy sources for dissection, the different techniques to control the renal hilum, the repair of an inferior vena cava injury, and the comparison between the Anderson-Hyne's and Foley's Y-V pyeloplasty. Results and Conclusion: Retroperitoneo...
TL;DR: A patient with left ureteropelvic junction obstruction and ipsilateral multiple calyceal stones is reported who benefited from innovative LESS pyeloplasty with concomitant pyelolithotomy using flexible cystoscope.
Abstract: Introduction: Laparoscopic pyeloplasty has been demonstrated the feasibility with similar success rates compared with open surgery, but with decreased postoperative pain and hospital stay.1 Recently, less invasive surgical technique, laparoendoscopic single-site surgery (LESS), has been developed.2 Clinical feasibility and usefulness of LESS kidney surgery already has been demonstrated in comparative study with conventional laparoscopic surgery.3 Herein we report a patient who benefited from innovative LESS pyeloplasty with concomitant pyelolithotomy. Materials and Methods: A 36-year-old man presented with left ureteropelvic junction obstruction and ipsilateral multiple calyceal stones. He had left flank pain for 3 months. He was found to have ureteropelvic junction obstruction with multiple calyceal stones at other hospital using kidneys, ureters, and bladder radiograph and computed tomography. He underwent umbilical LESS pyeloplasty with concomitant pyelolithotomy using flexible cystoscope. We ...
TL;DR: Five crucial surgical steps of a true retrograde Thulium laser enucleation of the prostate (ThuLEP) are presented, including incision of the verumontanum, middle lobe en nucleation, apical lateral lobe incision, bilateral lobe enucleations, and morcellation.
Abstract: Introduction: Bladder outlet obstruction caused by benign prostate hyperplasia is a very common problem in urologic male patients. For large glands of >60 cc, several accepted treatment options are available: open transvesical adenomectomy, Holmium laser enucleation of the prostate, and Greenlight™ photoselective vaporization of the prostate.1–14 In this video, we present the five crucial surgical steps of a true retrograde Thulium laser enucleation of the prostate (ThuLEP).15 Method: A 69-year-old man with bladder outlet obstruction (prostate volume 79 cc, International Prostate Symptom Score [IPSS] 33, prostate-specific antigen [PSA] level 5.15 ng/mL, and post-void residual 50 cc) underwent ThuLEP. The five crucial steps of the procedure are presented in the video: incision of the verumontanum, middle lobe enucleation, apical lateral lobe incision, bilateral lobe enucleation, and morcellation. Results: The operating time was 62 minutes; the perioperative blood loss was 0.5 g/dL. The patient was...
TL;DR: A posterior approach was attempted in 89 consecutive transperitoneal robotic prostatectomies, and in this video the subjective advantages are discussed, and the technique demonstrated.
Abstract: Introduction: The technical description of laparoscopic prostatectomy from Montsouris1 included an initial posterior retrovesical approach to the vas and seminal vesicles, followed by Denonviller's fascia incision and posterior release of the rectum. At that time, the feasibility of dissecting these structures following the posterior bladder neck dissection was not known, and therefore the posterior approach was largely performed out of necessity. Currently, the majority of minimally invasive surgeons perform an anterior approach to the vas and seminal vesicle dissection, and the anatomy of an initial posterior dissection is therefore unfamiliar. Since April 2009, the senior author (D.C.) has switched to the posterior approach, and in this video the subjective advantages are discussed, and the technique demonstrated. Materials and Methods: Between April 2009 and April 2010, a posterior approach was attempted in 89 consecutive transperitoneal robotic prostatectomies. A four-arm DaVinci S-HD system...

TL;DR: A retrospective study of prospective data on 1934 ureteroscopic stone manipulation procedures performed at Saudi German Hospital–Jeddah from January 2001 to January 2011 found that all these three cases were managed successfully by the novel endoscopic technique presented in this video.
Abstract: Introduction: This video presents our novel endoscopic technique for management of complete ureteral avulsion from uretero-vesical junction (UVJ). Materials and Methods: A retrospective study of prospective data on 1934 ureteroscopic stone manipulation procedures performed at our Urology Department in Saudi German Hospital–Jeddah from January 2001 to January 2011 was conducted. The ureterorenoscope used was an 8F, Storz, semirigid ureterorenoscope. During this period, three cases of complete ureteral avulsion from UVJ were recorded. All these three cases were managed successfully by our novel endoscopic technique that we present in this video. Surgical Procedure: Postavulsion event, the ureteroscope is withdrawn outside the patient keeping the guidewire (GW) in place. A Double-J (DJ) stent is then applied along the GW up to the kidney. The ureteroscope is then reinserted into the bladder, and guided by the DJ through the avulsion site into the retro peritoneum up to the lower end of the avulsed u...
