BACKGROUND: Descemet membrane endothelial keratoplasty (DMEK) is becoming more and more the method of choice to treat corneal endothelial diseases in specialized centers. The reasons that prevent this technique from becoming widespread are the delicate donor tissue preparation. By inverting the curvature of the cornea from convex to concave after mounting onto an artificial anterior chamber, we developed a combined manual delamination and hydrodissection technique, which allows a rapid and endothelium-preserving method of separating donor Descemet membranes from the underlying stroma...

PURPOSE: To investigate the microstructure of endothelial keratoplasty grafts using two-photon optical microscopy. METHODS: Six endothelial keratoplasty grafts obtained from human donor corneoscleral tissues and prepared by submerged hydrodissection technique were imaged by two-photon optical microscopy. In each graft, two liquid bubbles were created in order to investigate the presence of a conserved cleavage plane regardless of the volume of posterior stroma that remained attached to Descemet's membrane (DM); the first bubble (bubble A) was generated under DM and the second bubble (bubble B) injection was done in order to obtain a layer of deep stroma that kept the two bubbles separated...

BACKGROUND: Laparoscopic percutaneous extraperitoneal closure (LPEC) of the internal ring is a well-developed procedure for pediatric inguinal hernia and hydrocele. To reduce the skin incisions and improve the cosmesis, single-site LPEC (SLPEC) has been developed with numerous techniques and instruments. In this study, we described our modifications of SLPEC using an epidural and spinal needle in a large pediatric population. METHODS: From February 2013 to February 2016, 1464 pediatric patients who underwent SLPEC in our hospital were retrospectively reviewed...

Use of the phaco tip technique for lens cleavage and removal does not require manual hydrodissection using a syringe and cannula, or cortical removal using an irrigation/aspiration tip. The phaco tip is the only surgical instrument required for this technique. Its advantages include maintaining a stable intraocular pressure during cortical cleaving hydrodissection and lens removal, which includes the cortex.

INTRODUCTION: Transobturator slings can be successfully used to treat stress urinary incontinence and improve quality of life through a minimally invasive vaginal approach. Persistent postoperative pain can occur and pose diagnostic and therapeutic dilemmas. Following a sling procedure, a patient complained of pinching clitoral and perineal pain. Her symptoms of localized clitoral pinching and pain became generalized over the ensuing years, eventually encompassing the entire left vulvovaginal region...

OBJECTIVES: This study aimed to compare the effect of periurethral infiltration of bupivacaine versus normal saline on postoperative voiding function and pain in patients undergoing retropubic midurethral sling METHODS: A randomized double-blind placebo-controlled study was performed at the University of Massachusetts from March 2012 to June 2015. Ninety patients were randomized to receive 0.5% bupivacaine with epinephrine or normal saline with epinephrine solution for periurethral hydrodissection...

BACKGROUND: The aim of the study was to reach a consensus on indication and application of a hydrogel spacer based on multicentre experience and give new users important information to shorten the learning curve for this innovative technique. METHODS: The interdisciplinary meeting was attended by radiation oncologists and urologists, each with experience of 23 - 138 hydrogel injections (SpaceOAR®) in prostate cancer patients before dose-escalated radiotherapy. User experience was discussed and questions were defined to comprise practical information relevant for successful hydrogel injection and treatment...

PURPOSE: To evaluate the results and complications of phacoemulsification surgery in eyes with posterior polar cataracts and compare the techniques of viscodissection and hydrodissection. METHODS: The medical records of 29 consecutive patients (16 males, 13 females) with posterior polar cataracts (44 eyes) who had undergone cataract surgery were retrospectively reviewed. Patients were divided into two groups according to the technique used; viscodissection was applied to the experimental group (group 1) and hydrodissection to the control group (group 2)...

PURPOSE: To determine the efficacy and safety of percutaneous hepatic wedge ablation in treating hepatic malignancies of the inferior margin. MATERIALS AND METHODS: 77 patients with hepatic malignancies at the inferior margin underwent percutaneous radiofrequency ablation (RFA). 32 patients underwent hepatic wedge ablation and 45 patients underwent conventional tumor ablation. Comparative analysis of the two groups was performed including gender, age, tumor size, number of ablation cycles, ablation duration, and injected hydrodissection volume...

OBJECTIVE: To develop an ovine model for teaching suspension laryngoscopy and phonosurgery. METHODS: The head and neck from 10 pre-pubescent sheep were harvested following humane euthanasia at the end of an in vivo protocol. No live animals were used in this study. The tissues were saline-perfused and refrigerated for 1-5 days. Suspension laryngoscopy was performed using adolescent Parsons and adult Kantor-Berci laryngoscopes suspended with a Benjamin-Parsons laryngoscope holder...

Adeno-associated virus (AAV) has emerged as the preferred vector for targeting gene expression to the retina. Subretinally injected AAV can efficiently transduce retinal pigment epithelium and photoreceptors in primate retina. Inner and middle primate retina can be transduced by intravitreally delivered AAV, but with low efficiency. This is due to dilution of vector, potential neutralization of capsid because it is not confined to the immune-privileged retinal compartment, and the presence of the inner limiting membrane (ILM), a barrier separating the vitreous from the neural retina...

The purpose of this article is to report 3 cases of Kager's fat pad scarring and tethering to the deep surface of the Achilles tendon in patients with Achilles tendinosis symptomatology. The 3 patients were diagnosed sonographically by the use of a dynamic maneuver we described and named the "Kager's squeeze" technique. The key finding for diagnosis is the deformation and bowing of the deep fibers of the Achilles tendon during dynamic squeezing of Kager's fat pad. After diagnosis, the patients were treated with ultrasound-guided hydrodissection and scar release to restore normal motion between Kager's fat pad and the Achilles tendon...

OBJECTIVE: This study was designed to describe the technique of percutaneous image-guided cryoablation with large-volume hydrodissection for the treatment of challenging mediastinal lesions. METHODS: Between March 2014 and June 2015, three patients (mean age 62.7 years) with four neoplastic anterior mediastinal lesions underwent five cryoablation procedures using large-volume hydrodissection. Procedures were performed under general anaesthesia using CT guidance...

INTRODUCTION: We present a video describing the technical considerations for performing a total colpocleisis in the management of symptomatic post-hysterectomy pelvic organ prolapse. METHODS: A 76-year old female presented with pelvic pressure and the presence of a palpable vaginal bulge. She had significant bother and had previously failed use of a pessary. She wasnot sexually active, with no plans for future sexual activity. Her medical history was significant for coronary artery disease with prior myocardial infarction...

INTRODUCTION: Nephron-sparing surgery is reporting satisfactory oncological results, with improved quality of life. The laparoscopic approach is technically complex and requires advanced skills; however, the use of robotic systems facilitates the transition to this procedure. With improved strategies for diagnosis and follow-up, as well as ablative technologies, the role of partial nephrectomy continuous to evolve. The use of water-jet technology to dissect and resect organs helps create anatomical planes in a relatively blood-free field, which improves vision and does not cause heat damage...

Objective To assess the cytotoxicity of products subsequent to a cleaning process based on a validated standard operating procedure (SOP), and a final rinse with different types of water: tap, deionized, distilled, treated by reverse osmosis and ultra-purified. Method This was an experimental and laboratory study. The sample consisted of 130 hydrodissection cannulas, 26 per experimental group, characterized according to type of water used in the final rinse. The samples were submitted to internal and external contamination challenge with a solution containing 20% defibrinated sheep blood and 80% of sodium chloride 0...
