[Extracorpreal shockwave lithotripsy in treatment of bilateral ureteral calculi with renal colic during emergency].

Objective: To evaluate the clinical efficacy of extracorporeal shockwave lithotripsy (ESWL) for bilateral ureteral stones with renal colic in emergency.

Methods: We retrospectively analyzed the clinical data of 86 patients suffered with sudden renal colic due to bilateral ureteral stones and treated with ESWL between January 2005 and January 2009.

Results: The success rate was 74.

[Analysis of the outcome of extracorporeal shock wave lithotripsy for renal calculia].

Objective: To evaluate the factors affecting the efficacy of extracorporeal shock wave lithotripsy (ESWL) for renal calculi.

Methods: Between January, 2004 and January, 2007, 316 patients (212 men and 104 women) with renal stone underwent ESWL. The correlations of the patients' age, gender, body mass index (BMI), disease course, pain, hematuria, stone size, location, side, number and hydronephrosis to the outcome of the treatment was analyzed.

[Factors affecting the outcome of extracorporeal shockwave lithotripsy for upper urinary tract stones].

Objective: To investigate the factors affecting the efficacy of extracorporeal shockwave lithotripsy (ESWL) for upper urinary tract stones.

Methods: Between January 2003 and January 2006, 366 patients with upper urinary tract stone underwent ESWL, and the results were identified by regular KUB/IVU or ultrasonography and evaluated 3 months after the treatment. The treatment success was defined as complete clearance of the stones without residual fragments.

[Selection of the imaging modalities for diagnosis of renal trauma: experience with 74 cases].

Objective: To explore the diagnostic approaches and values of the imaging modalities for traumatic renal injuries.

Methods: The clinical records of 74 cases of renal trauma treated in Nanfang Hospital were retrospectively reviewed to assess the diagnostic value of intravenous urography (IVU), type B ultrasonography and computed tomography (CT).

Results: The positivity rates by IVU, type B ultrasonography, and CT were 89% (43/49), 80% (55/68) and 100% (51/51) respectively for the diagnosis of renal trauma.

[Application of self-controlled breathing technique in respiratory gating that triggers the shockwave for lithotripsy of urinary calculi].

Objective: To review our experience with the application of respiratory gating technique in extracorporeal shock wave lithotripsy (ESWL).

Methods: According to the established criteria 424 patients with urinary calculi were included in this study to received ESWL. These patients were divided into three groups, in which different breathing techniques were used for ESWL: group A with free breathing, group B with basically normal breathing except for the breath-holding upon each shockwave triggering, and group C with controlled breathing acquired from preoperative training.

Extracorporeal shock wave lithotripsy for difficulty in withdrawal of double J ureteral stents due to ureteral lithiasis.

Objective: To explore the efficacy of extracorporeal shock wave lithotripsy (ESWL) to coping with lithiasis-induced difficulty in withdrawing double J ureteral stents.

Methods: This study includes 6 patients with difficulty in withdrawing the stents due to lithiasis, who were in the anterior prone position or posterior oblique supine position to receive ESWL treatment. The stones were localized by double-band intersection X-ray system.
