Purpose of review Ureteral stents are necessary in the routine practice of an urologist. Choosing the correct stent and being aware of the options available will allow urologists to provide the best possible care for patients and value to the healthcare system. This review seeks to educate urologists regarding improvements in stent technology currently available or in development. Recent findings Research from around the world is underway to discover an ideal stent – one that is comfortable for patients, resists infection and encrustation and is affordable for hospital systems. Stent design alterations and stent...

Abstract Compared with adults, urolithiasis is quite rare in children (1-2% of all urinary stones occur during childhood). In principle, all therapy modalities for adults can also be used in children. However, due to some anatomic and functional peculiarities in children, the differential indication for the various treatment modalities differ. As a rule, asymptomatic renal stones are not treated but observed. More urinary stones pass spontaneously in children compared with adults. If spontaneous passage is not possible or does not occur, noninvasive and minimally invasive techniques are indicated. Extracorpor...

Authors: Kaya C, Kaynak Y, Karabag A, Aykaç A Abstract BACKGROUND: Our aim was to detect the role of radiological abdominal fat parameters by tomography and stone density by plain X-ray on extracorporeal Shock Wave Lithotripsy (SWL) stone-free rate. METHODS: The patients who had undergone SWL for a single opaque renal stone

This study aims to investigate whether 3D-MSD can predict ureteroscopic lithotripsy outcome. We retrospectively identified 218 patients who underwent ureteroscopic lithotripsy for kidney stones (n = 135) and ureteral stones (n = 83) between February 2011 and April 2017 with pretreatment non-contrast computed tomography (NCCT) at our hospital. Stone volume and 3D-MSD were automatically measured using high functional viewer. Logistic regression analysis was performed to identify factors contributing to treatment failur e. Treatment failure was determined as residual fragments ≥ 4&...

CONCLUSIONS: Although preoperative use of silodosin facilitated only an insignificant positive effect on UAS placement failure, it eased the F-URS procedure by reducing the ETBT, ETUOT, and AAST in seconds. More studies are needed to make an exact conclusion. PMID: 31950923 [PubMed - in process]

CONCLUSIONS: Tubeless PCNL encompasses lower morbidity and should be considered as an option for select patients, particularly with less stone burden and uncomplicated procedures. Regarding ureteral stents, SL is a safe option and does not require further procedures for removal. PMID: 31920064 [PubMed - as supplied by publisher]

AbstractTo determine the best time to perform EPVL treatment by evaluating the efficacy and safety of active stone extraction in treating residual fragments at different time points after RIRS. All participants had renal or upper ureteral stones preoperatively and still had residual stones after receiving RIRS. They were prospectively randomized into four groups: patients in group A received EPVL 3  days after RIRS; patients in group B received EPVL 7 days after RIRS; patients in group C received EPVL 14 days after RIRS; patients in group D did not receive EPVL after RIRS. Follow-up examinations were perform...

AbstractTo compare outcomes of a single middle calyx access (MCA) with a single upper or lower calyceal access in mini-PCNL. From May 2015 through August 2018, patients ’ files who underwent a single renal access mini-PCNL were retrospectively reviewed. All patients underwent fluoroscopic-guided access (16–20 F) in the prone position. They were categorized into group 1 (MCA) and group 2 (either upper or lower calyceal access). Compared preoperative items includ ed stone location, size, number and complexity (according to Guy’s score). The compared outcome parameters were complication and stone-free rates....

CAMBRIDGE (CBS) – A new treatment could help ease the passage of kidney stones, according to researchers at MIT and Massachusetts General Hospital. Scientists said this week that muscle relaxants can reduce the contractions that cause pain when passing the stones. About 1 in 10 people will have the painful experience of kidney stones. They cause more than 500,000 emergency room visits in the United States every year. But local researchers think they’ve made a discovery that can help. They say delivering a combination of two muscle relaxants directly to the ureter, the tube that connects the kidneys and bladder,...

Researchers at MIT have identified a combination of muscle-relaxing drugs that, when administered to the ureter, eliminated pain in pigs with kidney stones. It would be the first new treatment in 40 years.
