Biliary and pancreatic lithotripsy devices.

VideoGIE 2018 Nov 26;3(11):329-338. Epub 2018 Sep 26.

Background And Aims: Lithotripsy is a procedure for fragmentation or destruction of stones to facilitate their removal or passage from the biliary or pancreatic ducts. Although most stones may be removed endoscopically using conventional techniques such as endoscopic sphincterotomy in combination with balloon or basket extraction, lithotripsy may be required for clearance of large, impacted, or irregularly shaped stones. Several modalities have been described, including intracorporeal techniques such as mechanical lithotripsy (ML), electrohydraulic lithotripsy (EHL), and laser lithotripsy, as well as extracorporeal shock-wave lithotripsy (ESWL).

Urolithiasis 2018 Feb 4;46(1):19-29. Epub 2017 Dec 4.

Department of Urology, University Clinic Mannheim, Theodor Kutzer Ufer 1-3, 68167, Mannheim, Germany.

Since the introduction of ESWL, PNL and URS during the early 1980s the application rate of ESWL has declined while those of PNL and URS have increased. This is mainly due to the facts that instruments and techniques for Intracorporeal Lithotripsy (IL) have made a continuous progress. This review shows that today an array of options for IL within the entire urinary tract is available to treat stones in a perfect minimal invasive way. Read More

Ureteroscopy from the recent past to the near future.

Urolithiasis 2018 Feb 29;46(1):31-37. Epub 2017 Nov 29.

Uroclínica - Centro Clinico de Urologia, Campo Grande 30 1B, 1700-093, Lisboa, Portugal.

Stone surgery is one of oldest surgical practices undertaken by man. Hippocrates refused to let his followers "cut for the stone" and it was only in February 1980, when the first human trial of shock wave therapy on a renal stone was performed with success that a new era in minimally invasive treatment (surgery) for stones was opened up and this condemnation was finally resolved in the Hippocratic Oath. Endoscopy, using natural orifices, supported by anaesthesia, incremented by technology and with access to all points along the urinary tract, began by competing with ESWL, but is now the treatment of choice in most cases.

Modern management of paediatric obstructive salivary disorders: long-term clinical experience.

Acta Otorhinolaryngol Ital 2017 Apr;37(2):160-167

Department of Otolaryngology and Head and Neck Surgery, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.

Recent technological improvements in head and neck field have changed diagnostic and therapeutic strategies for salivary disorders. Diagnosis is now based on colour Doppler ultrasonography (US), magnetic resonance (MR) sialography and cone beam 3D computed tomography (CT), and extra- and intracorporeal lithotripsy, interventional sialendscopy and sialendoscopy-assisted surgery are used as minimally invasive, conservative procedures for functional preservation of the affected gland. We evaluated the results of our long-term experience in the management of paediatric obstructive salivary disorders. Read More

Salivary lithotripsy in the era of sialendoscopy.

Acta Otorhinolaryngol Ital 2017 Apr;37(2):113-121

Department of Otorhinolaryngology, Head and Neck Surgery; Friedrich Alexander University of Erlangen Nuremberg, Germany.

The traditional management of obstructive salivary disorders has been replaced by minimally-invasive gland-preserving techniques including shock-wave lithotripsy, sialendoscopy, interventional radiology and endoscopically video-assisted trans-oral and cervical stone retrieval, of which sialendoscopy is considered to be the method of first choice. Primary endoscopically controlled stone extraction without prior fragmentation is only possible in 15-20% of cases; in more than 80%, fragmentation is necessary because of the size, impactation and location of the stone, or an alternative treatment such as transoral duct surgery or combined approaches are required. Moreover, about 10-20% of all stones cannot be adequately accessed by means of a sialendoscope or any alternative surgical method and, in such cases, extra-corporeal shock wave lithotripsy (ESWL) is the treatment of choice.

[Laser lithotripsy].

Urologiia 2015 Dec(6):116-121

Scientific-Technical Association IRE-Polus.

The article describes the diverse methods of stone destruction in urolithiasis patients, including laser lithotripsy as the least traumatic and most efficient method of demolition of all types of urinary stones. Different types of lasers for intracorporeal lithotripsy have different mechanisms of stone fragmentation depending on the type of laser and its radiation parameters. The latest researches showed that new and promising laser modalities for lithotripsy are devices based on thulium (Tm) doped fiber laser, which can not only increase by several times the speed of the of stone fragmentation, but also minimizes the risks of surgical complications, due to the peculiarities of interaction between radiation and biological tissues.

Prague Med Rep 2015 ;116(3):225-32

Department of Urology, Hadassah Hebrew University Medical Center, Jerusalem, Israel.

To evaluate the impact of ureteral stenting history to the outcomes of extracorporeal shockwave lithotripsy, we retrospectively analysed patients who underwent shockwave lithotripsy with Dornier Gemini lithotripter between September 2010 and August 2012. Forty seven patients (group A) who had a double J stent which was removed just before the procedure were matched-paired with another 47 patients (group B) who underwent shockwave lithotripsy having no stent history. The correlation between ureteral stenting history and stone-free rates was assessed. Read More

Can Urol Assoc J 2015 Jul-Aug;9(7-8):E494-9

Glickman Urological and Kidney Institute, Cleveland Clinic Foundation, Cleveland, OH.

The management of encrusted ureteral stents is costly, time consuming and may be risky for the patient and challenging for the urologist. Treatment modalities for encrusted stents include extracorporeal shock wave lithotripsy, cystolithopaxy, rigid or flexible ureteroscopy with intracorporeal lithotripsy, percutaneous nephrolithotomy, open surgery, and a combination of those methods. In this study we describe the management of severe forgotten encrusted ureteral stents in 3 female patients using a prone split-leg position. Read More
