INTRODUCTION: Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic renal inflammation, caused by long-term obstruction of the urinary tract. Pyonephrosis is a severe suppurative complication of acute obstructive pyelonephritis. Although minimally invasive approaches have many advantages, the safe dissection of the kidney may not be always achievable. MATERIALS AND METHODS: We reviewed 27 cases diagnosed with either XGPN or pyonephrosis, who underwent laparoscopic total nephrectomy between October 2016 and March 2022 in our department...

OBJECTIVE: The aim of this paper is to describe the use of high-definition 3D exoscope (VITOM 3D exoscope - Karl Storz GmbH, Tuttlingen, Germany) for the neurosurgical treatment of a rare pediatric disease, type II diastematomyelia with associated tethered cord. METHODS: A 13-year-old girl suffering diastematomyelia type II with a tethered cord was surgically treated with the aid of a high-definition 3D exoscope, with a third operator moving and pivoting its arm...

INTRODUCTION: The Karl Storz FLEX-XC1 is a novel single-use flexible ureteroscope that uses the same videographics platform as its reusable digital counterpart. We evaluated the technical performance of the FLEX-XC1 in its initial clinical use. METHODS: We reviewed a series of consecutive ureteroscopy procedures performed by 2 endourologists using the FLEX-XC1 for indications for which we typically use a single-use device: total stone burden >15 mm or >10 mm in the lower pole, anticipated case duration >60 minutes, bilateral procedure, or upper tract urothelial cancer procedures...

OBJECTIVES: Using a laboratory-based optical setup we show that 5ALA fluorescence is better detected using the endoscope than the microscope. Furthermore, we present our case series of fully-endoscopic 5ALA guided resection of intraparenchymal tumors. METHODS: A Zeiss Pentero® microscope was compared to the Karl Storz Hopkins® endoscope. The spectra and intensity of each blue light source were measured. Quantitative fluorescence detection thresholds were measured using a spectrometer...

OBJECTIVE: Transurethral resection of bladder tumor is one of the most common everyday urological procedures. This kind of surgery demands a set of skills that need training and experience. In this review, we aimed to investigate the current literature to find out if simulators, phantoms, and other training models could be used as a tool for teaching urologists. METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement and the recommendations of the European Association of Urology guidelines for conducting systematic reviews...

OBJECTIVE: To demonstrate the safety, efficacy, and ease of hysteroscopic metroplasty using Holmium YAG Laser for treatment of septate uterus. DESIGN: Stepwise demonstration of surgical technique with narrated video footage. SETTING: Septate uterus is the most common type of uterine anomaly. The incidence of uterine septum in women presenting with infertility and recurrent abortions is 15.4% (1)(2). Hysteroscopic septal incision is associated with improvement in live-birth rate in these women (3)...

OBJECTIVE: Demonstrate the usefulness of using indocyanine green after laparoscopic ovarian detorsion to save the ovary. DESIGN: A step-by-step video demonstration of a surgical technique. SETTING: Ovarian torsion is one of the most common gynecological emergencies, mainly affecting patients younger than 20 years of age [1], and causes 2% to 7% of acute abdomens [2]. It is not advisable to routinely perform ovariectomy even with a necrotic ovary appearance [1]...

PURPOSE: Nasotracheal intubation (NTI) is required for surgery in oropharyngeal (OP) carcinoma patients, but it may be challenging because of distorted anatomy, mucosal congestion, and increased risk of bleeding. Flexible bronchoscopy (FB)-guided NTI is preferred in these cases but has limitations. In this randomized controlled study, we sought to compare C-MAC® D-BLADE-guided videolaryngoscopy (VL) (Karl Storz SE & Co. KG, Tuttlingen, Germany) with FB for NTI under general anesthesia in patients with OP carcinomas...

INTRODUCTION: The most dreaded complication during laparoscopic cholecystectomy still remains to be injury to the common bile duct. The primary cause for bile duct injury during LC is misinterpretation of the biliary anatomy. Intra-operative cholangiography was introduced as a means of reducing the chances of biliary injury, done using Fluoroscopic imaging or Near-infrared fluorescence imaging method. NIRF is one of the most popular imaging methods in biomedical sciences. Indocyanine Green is sterile and water soluble which completely binds to albumin and is excreted in bile...

BACKGROUND: Macintosh blade direct laryngoscopy is widely used for endotracheal intubation. It may, however, provide an incomplete view of the glottis in patients with challenging airway anatomy. Consequently, various video laryngoscopes have been developed to enhance the visualization of the glottis and facilitate intubation. Yet, the effectiveness of these video laryngoscopes for intubation using a double-lumen endotracheal tube (DLT), which is longer, larger, and more rigid and has a linear configuration as opposed to the naturally semicircular curvature of a single-lumen endotracheal tube, remains uncertain...

This cross-sectional study aimed at exploring the frequency and extent of knee joint lesions associated with delayed treatment of anterior cruciate ligament (ACL) injury. It enrolled 300 patients from 2020 to 2022 who were subjected to arthroscopy for anterior cruciate ligament reconstruction. The sample was comprised of Iraqi adult male patients from different regions of Iraq, and the surgical procedure was carried out in Al-Diwaniyah Teaching Hospital. The findings were recorded by Karl Storz's camera system...

INTRODUCTION: In gynaecology, laparoscopy is the choice of treatment for a lot of procedures as it is considered safe and effective. However, laparoscopic surgery requires skills that are different from those required for open surgery. In order to acquire the skills, a surgeon needs specific training. The aim of this study was to validate the AR Gynae endotrainer, a new mobile laparoscopic simulator, as a comparable box trainer for gynaecology laparoscopic training, comparing it with the well-established Karl Storz SZABO-BERCISACKIER laparoscopic trainer...

OBJECTIVE: Studies have shown a bougie improves first-attempt success rates when used in combination with direct laryngoscopy during the initial attempt. The purpose of this study was to determine whether the use of a bougie in combination with C-MAC (Karl Storz, Tuttlingen, Germany) improves first-attempt success rates of endotracheal intubation (ETI) compared with C-MAC with a traditional stylet. METHODS: This study is a retrospective chart review using data collected on 371 intubations completed by a single air medical service using the C-MAC laryngoscope and either a bougie or a stylet...

Thirteen adult healthy captive skinks, six Gidgee spiny-tailed skinks ( Egernia stokesii ), three Hosmer's spiny-tailed skinks ( Egernia hosmeri ) and four tree crevice-skinks ( Egernia striolata ), were submitted to the study. The weight of the animals ranged from 28 g to 146 g. All skinks were explored during their putative mating season, which is December. Lizards were restrained manually and positioned in ventral recumbence. Cloacoscopy was performed with the rigid endoscope, protecting channel, endocamera and recording system Telepack-Pal (Karl Storz Endoskope, Tuttlingen, Germany)...

INTRODUCTION: The vortex effect (VE) is widely utilized in mini-percutaneous nephrolithotomy (mini-PCNL), despite its physical components being still poorly understood. This study aimed to analyze the influence of different renal access angles and nephroscope retrieval speeds on the VE's efficacy for mini-PCNL. MATERIALS AND METHODS: A Pexiglas™ (KUS®) model was built based on the dimensions of a 15/16F mini-PCNL set (Karl Storz®). The flow rate was continuous via an automatic pump and calibrated to achieve hydrodynamic equivalence to the real equipment...

PURPOSE: Chyle leak resulting from thoracic duct (TD) injury poses significant morbidity and mortality challenges. We assessed the feasibility of using near-infrared (NIR) indocyanine green (ICG) imaging for intraoperative fluorescence TD lymphography during minimal access esophagectomy (MAE) in a semiprone position with inguinal nodal injection of ICG dye. METHODS: Ninety-nine patients with esophageal or gastroesophageal junctional cancer undergoing MAE received inguinal node injections of 2...

OBJECTIVE: To enhance visualization in pediatric Otolaryngology middle ear surgeries and reduce mastoidectomy instances, we introduce a novel Articulating Chip-on-Tip Endoscope (ACoT Endo). METHODS: The ACoT Endo incorporates a cable driven distal end camera and off-the-shelf Chip-on- Tip camera to improve visualization. We compared its capabilities with standard endoscopes, evaluating its bending capacity (70 ±2) and center axis rotation (360). To test the overall functionality of this device, a Mock Ear was created to simulate the anatomy of the human ear, and the ACoT Endo's ability to be used in this cavity is compared to a standard 0 Karl Storz endoscope through tests with the Mock Ear and respective endoscopes...

INTRODUCTION: Flexible ureterorenoscopy (fURS) has become one of the most frequent procedures in urology in recent years. The main problem on the way of the spread of flexible ureterorenoscopy in everyday urological practice all over the world is the fragility of endoscopes. MAIN AIM: To evaluate the potential use of reusable and single-use ureterorenoscopes for kidney stones. MATERIALS AND METHODS: The analysis included 30 patients who underwent of retrograde intrarenal surgery (RIRS) for kidney stones...

BACKGROUND: During minimal access surgery, surgical smoke is produced which can potentially be inhaled by the surgical team, leading to several health risks. This smoke can escape from the abdominal cavity into the operating room due to trocar leakage. The trocars and insufflator that are used during surgery influence gas leakage. Therefore, this study compares particle escape from a valveless (Conmed AirSeal iFS), and a conventional (Karl Storz Endoflator) system. MATERIALS AND METHODS: Using an in vitro model, a conventional and a valveless trocar system were compared...

BACKGROUND: Indocyanine green fluorescence technology (ICG) in pediatric minimally invasive surgery has undergone an important improvement in the last 5 years. However, its use in open surgery is still limited. In this paper, we aim to report our preliminary experience with Rubina® lens ICG fluorescence technology in combination with the IMAGE1 S™ system from KARL STORZ in open excision of masses in children. METHODS: The records of 18 patients undergoing open surgery for head, neck and thorax masses between September and November 2022 were retrospectively reviewed...
