Randomized Controlled Trial Comparative StudySupplementary X-ray for ultrasound-guided percutaneous nephrolithotomy in supine position versus standard technique: a randomized controlled trial.
To compare the success and complication rates of sonography-guided supine percutaneous nephrolithotomy (PCNL) versus prone standard technique (fluoroscopic guidance) in a randomized controlled trial. ⋯ In this study, sonography-guided supine PCNL was presented as a safe and effective technique, similar to standard PCNL, with comparable success and complication rates. In addition, using this technique eliminates the possible harmful impacts of radiation on the surgical team and decreases postoperative fever.

Case ReportsRelease of the inferior vena cava ligament during caval thrombectomy causing tumor thrombus embolization.
Intraoperative tumor embolization is a rare complication during the surgical management of renal cell carcinoma with tumor thrombus of the inferior vena cava (IVC). We present a case of pulmonary tumor embolism which occurred during liver mobilization immediately following division of the IVC ligament. We hypothesize that this patient's IVC ligament acted as an external barrier to propagation of the tumor thrombus and that its release caused the tumor to rapidly expand leading to embolization. To our knowledge, this is the first report of a pulmonary tumor embolism occurring immediately following division of the IVC ligament.

The role of transarterial embolization in the management of hematuria secondary to congenital renal arteriovenous malformations.
To evaluate the efficacy and safety of transarterial embolization (TAE) in the management of hematuria secondary to congenital renal arteriovenous malformations (AVM). ⋯ For unexplained massive hematuria, congenital renal AVM needs to be considered as a differential diagnosis. Selective renal angiography and embolization should be recommended as the first choice to treat massive hematuria secondary to congenital renal AVM.

Inherent grading characteristics of individual pathologists contribute to clinically and prognostically relevant interobserver discordance concerning Broders' grading of penile squamous cell carcinomas.
We assessed the reproducibility and prognostic impact of the Broders' grading system (BGS) in a cohort of 147 patients with surgically treated penile squamous cell carcinomas. ⋯ Clinically and prognostically relevant interobserver discordance concerning the BGS seems, at least in part, to be attributable to inherent 'aggressive' versus 'reserved' grading characteristics of individual pathologists.

Comparative StudyComparison of percutaneous nephrolithotomy, shock wave lithotripsy, and retrograde intrarenal surgery for lower pole renal calculi 10-20 mm.
To compare the results of percutaneous nephrolithotomy (PCNL), shock wave lithotripsy (SWL), and retrograde intrarenal surgery (RIRS) for 1- to 2-cm lower pole kidney stones. ⋯ PCNL seems to be the most successful but most invasive method. However, with relatively low complication rates, SWL and RIRS are other techniques to keep in mind. To determine the first-line treatment, prospective randomized studies with larger series are needed.
