BACKGROUND: The optimal treatment for distal ureteral calculi remains controversial. We present data from our institution to compare the efficacy of extracorporeal shockwave lithotripsy (SWL) and ureteroscopy with different lithotripsy modalities (URSL). METHODS: From January 1994 to September 1997, 954 distal ureteral calculi were treated at our institution using in ...

BACKGROUND AND STUDY AIMS: Endoscopic sphincterotomy (EST) is the standard procedure for gaining access to the common bile duct for removal of bile duct stones. However, the procedure is associated with both short-term and long-term complications. Recent reports have described the use of endoscopic papillary balloon dilation (EBD) as an ...

Retroperitoneoscopic ureterolithotomy was successfully performed in two patients with impacted upper ureteral stone. The retroperitoneal space was extended using a balloon dissector and four ports were established into the retroperitoneal space according to Gaur's procedure (1993). The impacted ureteral stone was removed after the ureter was incised using a hook ...

Andreoni C - - 2001
BACKGROUND AND PURPOSE: The surgical treatment of kidney and proximal ureteral stones in morbidly obese patients (>14 kg/m2) remains difficult because shockwave lithotripsy is precluded by weight limitations and percutaneous nephrolithotomy is associated with difficult access and a high (9%) rate of transfusion. We review our experience with retrograde ureteroscopic ...

Strohmaier W L - - 2000
OBJECTIVE: Several studies reported increased blood pressure (BP) values following extracorporeal shock wave lithotripsy (ESWL) treatment of renal stones. It is unclear, however, whether this is due to ESWL, since nephrolithiasis itself increases the relative risk of developing hypertension. Therefore we prospectively studied the BPs of stone patients undergoing different ...
Pace K T - - 2000
PURPOSE: We determined the number of shock wave lithotripsy treatments that should be given for a single ureteral stone before alternate modalities are used. MATERIALS AND METHODS: We compared the stone-free rate of initial shock wave lithotripsy for ureteral calculi with that of subsequent treatments. We evaluated 1,593 ureteral stones ...

The increasing popularity of 3-D planning leads to procedural alterations as both workload and resource utilization increase. Although the complexity of the techniques has increased (as well as the set-up and treatment times), the workload statistics must still include the number of fields treated. It is commonly known that machine ...

Endoscopic lithotripsy is an essential part of the armamentarium at any complete stone treatment center. It is first-line therapy for complicated upper urinary tract calculi and for patients who fail primary extracorporeal shock wave lithotripsy. In the presented series, ureteroscopy is defined as a safe and particularly effective treatment for ...

When bile duct stones cannot be removed after sphincterotomy by balloon or basket extraction, stent placement can serve as a bridge to additional procedures. Biliary stents may also fragment large stones, allowing them to pass spontaneously or making them easier to extract at a later time. Twenty patients with difficult ...

OBJECTIVE: To evaluate prospectively the efficacy of extracorporeal shock wave therapy (ESWT) as a conservative treatment for Peyronie's disease. PATIENTS AND METHODS: After obtaining ethical committee approval, 37 patients with Peyronie's disease were treated using ESWT.

PURPOSE: The American Urological Association (AUA) published clinical guidelines for the treatment of ureteral calculi in adults and note that up to 98% of stones less than 5 mm. in diameter will pass spontaneously. Ureteroscopy and shock wave lithotripsy were acceptable treatment choices for stones less than 10 mm. in ...
Fialkov J M - - 2000
PURPOSE: The Dornier MFL-5000* is a multifunctional lithotriptor unit that has been purported to be highly efficacious for treating stones. Our experience led us to believe that the actual success rates are not as high as those reported by others. We objectively reexamined the efficacy of this device and factors ...

Sudden immersion in cold water initiates an inspiratory gasp response followed by uncontrollable hyperventilation and tachycardia. It is known that this response, termed the "cold shock" response, can be attenuated following repeated immersion. In the present investigation we examined how long this habituation lasts. Twelve healthy male volunteers participated in ...

Acropora palmata, a branching coral abundant on shallow reef environments throughout the Caribbean, is susceptible to physical disturbance caused by storms. Accordingly, the survivorship and propagation of this species are tied to its capability to recover after fragmentation. Fragments of A. palmata comprised 40% of ramets within populations that had ...

Not only is the diagnosis of isolated premature thelarche difficult to distinguish from other variants of premature sexual maturation, but within the subgroups of isolated premature thelarche, there are probably at least two subgroups: "classical" and "atypical". We do not appreciate how potential treatment could affect each group, although it ...
