Randomized Controlled Trial
Use of urokinase in percutaneous drainage of large breast abscesses.
The purpose of this study was to evaluate intracavitary urokinase therapy versus irrigation with a saline solution in percutaneous drainage of large breast abscesses. ⋯ Percutaneous drainage of large breast abscesses in nonlactating women with intracavitary urokinase irrigation is a simple and safe procedure. It reduces the treatment time and improves the clinical course of patients more than conventional drainage with saline irrigation.

Randomized Controlled Trial
A randomized controlled trial of ultrasound-assisted lumbar puncture.
Evidence showing the systematic utility of ultrasound imaging during lumbar puncture (LP) in the emergency department is lacking. Our hypothesis was that ultrasound-assisted LP would increase the success rate and ease of performing LP with a greater benefit in obese patients. ⋯ The use of ultrasound for LP significantly reduced the number of failures in all patients and improved the ease of the procedure in obese patients.

Randomized Controlled Trial
Is fluid ingestion really necessary during ultrasonography for detecting ureteral stones? A prospective randomized study.
Ultrasonographic evaluation of ureteral stones is usually performed after fluid ingestion for filling the bladder to visualize the ureterovesical junction better. We hypothesized that water ingestion may decrease the imaging quality of ultrasonography for detecting ureter stones. In our prospective randomized study, the accuracy of ultrasonography for detecting ureteral stones performed with or without fluid intake were evaluated. ⋯ This prospective randomized study showed that the diagnostic accuracy of ultrasonography for detection of middle ureteral stones increased significantly when performed without any water ingestion before the procedure. We recommend that patients thought to have ureteral stones should be first examined without any fluid ingestion.

Randomized Controlled Trial Comparative Study Clinical Trial
Treated needles: do they facilitate sonographically guided biopsies?
We sought to compare needle visualization and diagnostic yield rates resulting from the use of several commercially available treated needles in sonographically guided biopsies. ⋯ The echogenic polymer-coated needle was the best visualized of all needles evaluated, both treated and untreated. No significant difference was found in diagnostic yield rates, but that may be reflective of the relatively small sample size.

Randomized Controlled Trial Clinical Trial
Transvaginal ultrasonographic assessment of Hyskon or lactated Ringer's solution instillation after laparoscopy: randomized, controlled study.
We sought to evaluate two common fluids placed in the pelvis after pelvic surgery for their ability to remain in the pelvis for a time thought adequate for prevention of adhesions. Thirteen patients undergoing operative laparoscopy were randomized to receive 250 ml 32% dextran 70 (Hyskon), 250 ml lactated Ringer's solution, or no fluid (control) at the end of surgery. Serial transvaginal ultrasonograms were obtained at 1 hr, 3 hr, 6 hr, 24 hr, 96 hr (4 days), and 168 hr (7 days) after surgery. ⋯ One patient who received Hyskon developed severe vulvar edema and another developed dyspnea. We conclude that the volume of Hyskon in the peritoneal cavity after laparoscopy does not decline as rapidly as does that of lactated Ringer's solution; however, significant side effects may limit its usefulness. Transvaginal ultrasonography is useful in monitoring fluids placed in the pelvis for prevention of adhesions.
