A simple cost-effective design for construction of a laparoscopic trainer.
Laparoscopic trainers have been shown to be effective tools for transitioning residents in surgical fields into live laparoscopic techniques. There have been few reports of homemade trainers, but each of these reports provides only scant detail about their construction, making production a novel task to those interested in employing this equipment. Virtual-reality trainers are gaining popularity and are exceptional modalities in the re-creation of laparoscopic surgery. In their present state, however, such trainers are very costly, making them unattainable by most urology residency programs. Numerous commercial non-virtual trainers are also available; however, these trainers are often cost-prohibitive or overly simplistic. ⋯ The relatively low total cost, ready material availability, and ease of construction make this trainer an appropriate option for the training of residents in laparoscopic procedures.

Randomized Controlled Trial Clinical TrialEffectiveness of eutectic mixture of local anesthetic cream and occlusive dressing with low dosage of fentanyl for pain control during shockwave lithotripsy.
To investigate the effect and usefulness of Eutectic Mixture of Local Anesthetic (EMLA) applied with an occlusive dressing and used simultaneously with a low dose of fentanyl during shockwave lithotripsy (SWL). ⋯ Use of EMLA and an occlusive dressing with low doses of fentanyl during SWL provides appropriate analgesia with minimal morbidity.

Randomized Controlled Trial Clinical TrialRandomized double-blind comparison of lidocaine gel and plain lubricating gel in relieving pain during flexible cystoscopy.
To compare the pain induced by outpatient flexible cystoscopy in men having local lidocaine jelly application or plain lubricant. ⋯ Using plain lubricant is cheaper and faster than applying lidocaine gel. The pain score, pain grade, postcystoscopic analgesic requirement, and anesthetics requested for the next cystoscopy were similar in the two groups. However, a larger investigation will be needed to achieve more significant statistical power.

Randomized Controlled Trial Comparative Study Clinical TrialTransurethral electrovaporization of the prostate: is it any better than standard transurethral prostatectomy? 5-year follow-up.
At present, transurethral resection of the prostate (TURP) is regarded as the most effective treatment for benign prostate hyperplasia (BPH). In the present randomized study, we compared TURP with transurethral electrovaporization of the prostate (TUVP). ⋯ The TUVP procedure is as effective as TURP with similar morbidity. The advantages of TUVP are that the urethral catheter is withdrawn earlier, hospitalization is shorter, and bleeding is less. Its disadvantage is that tissue cannot be sampled for histologic diagnosis. In our opinion, in order to exploit the advantages of this technique, TUVP should be preferred in elderly patients without any suspicion of prostate cancer for whom bleeding during operation is a source of risk.

Comparative StudyPlasmaKinetic bipolar vessel sealing: burst pressures and thermal spread in an animal model.
Laparoscopic bipolar instruments are commonly employed to cauterize and divide tissue. A next-generation bipolar device has been developed that employs vapor pulse coagulation energy. We assessed the vessel-sealing capability of this device and quantified thermal spread during application. ⋯ The Gyrus PlasmaKinetic bipolar device is capable of reliably sealing/ dividing arteries as large as 6 mm, although we recommend restricting its use to vessels no larger than 5 mm in diameter to allow a safety margin. In addition, porcine renal veins of all sizes are adequately controlled. These sealed vessels are able to withstand pressures approaching 300 mm Hg. Thermal spread affects only the area surrounding the divided vessel. Further clinical studies are warranted.
