Kidney and Ureteral Stones.

Kidney and Ureteral Stones. Emerg Med Clin North Am. 2019 Nov;37(4):637-648 Authors: Corbo J, Wang J Abstract Renal colic is a common complaint that presents to the emergency department. It is estimated that 13% of men and 7% of women will develop a renal stone. There is a high probability of recurrence, with 50% within 5 years. Computed tomographic scan of the abdomen and pelvis without contrast and the ultrasound of the kidneys, ureters, and bladder are the common diagnostic imaging modalities used for diagnosis. Initial treatment includes analgesics and medical expulsive therapy. Most of the patients will pass their stone spontaneously within 3 days. The remaining 20% will require urologic intervention.

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.

ConclusionThe use of fluoroscopy does not alter the complication frequency and stone-free rate. We think that the use of fluoroscopy is not mandatory in cases in which renal pelvis access is achieved especially with semirigid ureteroscopy and that unnecessary fluoroscopy increases radiation exposure.RESUMENObjetivosEl objetivo de este estudio fue evaluar el rol de la aplicación de fluoroscopia en pacientes sometidos a cirugía retrógrada intrarrenal y su efecto sobre los resultados quirúrgicos.Material y métodosLos pacientes que ingresaron en nuestro centro con diagnostico de cálcul...

Radiographs can be used to easily visualize common types of urinary calculi in all parts of the urinary tract. Positive-contrast excretory urography and cystourethrography are sensitive to diseases within the ureters and urethra, most commonly obstruction. Ultrasound is widely available and noninvasive and can be used to evaluate renal architecture, ureteral dilation, urinary bladder wall disease, and urolithiasis. Computed tomography is increasing in availability and provides a large amount of cross-sectional information quickly and noninvasively. Multiple imaging modalities can be used to estimate or quantify glomerular filtration rate.

Conclusions Laparoscopic pyeloplasty with concomitant pyelolithotomy is a safe and effective intervention with associated good cosm etic results and high stone-free rates without significant increase in operative time or complications.
