Given the high recurrence of urolithiasis in patients, the search for less aggressive and preventive treatments is increasingly necessary. Renalof® is presented as an alternative to herbal medicine being a product that, due to its diuretic and demineralization properties of kidney stones, has been widely used in this patient population, disintegrating and eliminating calcium oxalate and struvite stones in a painless in the genitourinary system. With the objective of determining the efficacy of this therapy, an observational, prospective, randomized, single-blind, two-arm study was carried out: treatment group with Renalof® and control group, placebo.

Medical Expulsive Therapy of Single Distal Ureteral Stones

Ureteral Calculi

Current therapeutic options for ureteral stones include active intervention as well as conservative "watch and wait" approaches. Endoscopic treatment of ureteral stones has a high success rate and reliably results in immediate stone removal However, surgical as well as anaesthetic risks are not negligible and serious complications are possible. For many patients, a conservative treatment is an appealing option. Watchful waiting, however, not always results in stone clearance and may be associated with recurrent renal colics. The therapeutic potential of alpha-blockers for ureteral stone disease has been investigated prompted by the detection of alpha-receptors in ureteral smooth muscle cells. Blocking of such receptors, which are predominantly located in the distal part of the ureter results in relaxation of the ureteral wall and modulation of peristaltic activity. This mechanism has been proposed to facilitate stone passage for ureteral calculi. Numerous clinical trials have revealed a significant improvement of the stone expulsion rate using the alpha-blocker tamsulosin. Most of these studies were randomised but none were performed in a double-blind and placebo-controlled fashion. Therefore, the objective of this trial was to evaluate the efficacy of medical expulsive therapy with tamsulosin in a randomised, double-blind, placebo-controlled setting.

Nefopam and Morphine Consumption in the Treatment of Ureteral Calculi

Ureteral CalculiHyperalgic1 more

The administration of néfopam after initial treatment by kétoproféne, could obtain, in patients remaining pain and classically need morphine, analgesia at least the same as morphine alone. The use of néfopam second line after ketoprofen could reducing (or even eliminating) the need for morphine (and its side effects), allowing a reduction in the length of stay of patients in the emergency unit. The main objective is to show that the addition of a néfopam initial treatment with the kétoproféne, reduces, in patients with ureteral calculi, the percentage of patients requiring the use of a treatment by morphine. The secondary objective is to reduce the side effects caused by the morphine, shorten the time to install the appropriate level of analgesia while reducing the risk of failure of the titration morphine, reduce the time spent on titration of morphine and reduce the length of stay patient intake in emergency unit.

Ultrasound Guided Ureteroscopy and Ureteric Stones

Ureteric Stone

The prevalence of urolithiasis is steadily increasing with an estimation of 1 out of 11 people in the United States. The prevalence of calculi in Afro-Asian region including Arab Republic of Egypt ranges from 4% to 20%. Ureteroscopy is one of the first line treatments for definitive management of ureteric stones. Conventional ureteroscopy relies on intraoperative fluoroscopy for visualization and guidance, exposing the patient, surgeon and operating room staff to ionizing radiation. To minimize the hazards of ionizing radiation there has been a trend toward radiation free alternative imaging modalities . Ultrasound provides an excellent alternative for upper urinary tract imaging because it is radiation free, rapid, portable and allows excellent visualization of the renal pelvis and calyces. There is increasing awareness and concern about the clinical use of ionizing radiation and the need to decrease exposure of patients and medical professionals. Ultrasound guided ureteroscopy in pregnant females and children- in whom fluoroscopy is to be minimized or avoided when possible - has been reported.

Ureteroscopic Lithotripsy in the Reverse Trendelenburg Position for Upper Ureteral Stones

UreterolithiasisUreter Stone1 more

This study investigated a previously unassessed operating position for ureteroscopic holmium laser lithotripsy in patients with upper ureteral stone. The reverse Trendelenburg position can reduce migration and improve the stone free rate (SFR). Moreover, less utilization of flexible ureteroscope and hospital stay in reverse Trendelenburg position can reduce the medical cost. Therefore, it can be safely used as an optional surgical method for the treatment of upper ureteral stones.

The Efficacy of Tamsulosin in the Treatment of Ureteral Stones in Emergency Department Patients...

Kidney StonesUreteral Stones

To determine if emergency department patients with acute ureteral colic pain due to a ureteral stone who are treated with tamsulosin, versus placebo, will experience a shorter time to passage of their stone or resolution of their pain. A secondary study objective will be to determine if there is a relationship between response to tamsulosin and stone size or position in the ureter.
