Operating Endoscopically with "Two Hands" to Remove Calcified Permanent Suture After Pyeloplasty.

We describe a combined percutaneous and endoscopic approach to remove encrusted permanent suture in the renal pelvis that was placed during pyeloplasty repair. Our index patient had a laparoscopic dismembered pyeloplasty at an outside institution 10 years before presenting with flank pain and nondependent nephrolithiasis. This proved to be an encrusted permanent suture material.

Use of the Modification of Diet in Renal Disease Equation for Estimating Glomerular Filtration Rate in the Urologic Literature.

Purpose: To evaluate the use of the modification of diet in renal disease (MDRD) equation in the urologic literature and the degree to which it is used appropriately.

Methods: Medline was queried searching the title, keywords, or abstract of seven urology journals for the exact phrases "MDRD" or "modification of diet in renal disease." Forty-seven articles published between 2004 and 2013 met the inclusion criteria and were reviewed.

Fibromuscular Dysplasia in a Normotensive Patient Presented With Renal Infarct: Case Report and Endovascular Technique.

Fibromuscular dysplasia (FMD) is a well-known disease, but its diagnosis can be challenging. Typically, the symptomatic FMD are reported by young and middle aged people with high blood pressure refractory to medical treatment. We present a rare case of a young, healthy, and normotensive patient who presented with pain secondary to renal infarction, without any prior signs or symptoms or history of hypertension.

Intermediate-term outcomes after renal cryoablation: results of a multi-institutional study.

Purpose: To present intermediate-term oncologic efficacy of cryoablation (CA) for the treatment of patients with small renal masses in a multi-institution multisurgeon cohort.

Patients And Methods: We retrospectively reviewed billing records and tumor registries, identifying 116 renal tumors in 116 patients treated with CA by six surgeons at four institutions. Patient age, sex, tumor size, RENAL nephrometry score, complications, and recurrences were recorded.

Use of tumor necrosis factor-alpha-coated gold nanoparticles to enhance radiofrequency ablation in a translational model of renal tumors.

Objectives: Radiofrequency ablation (RFA) has been most effective when the tumors are small, exophytic, and away from vital structures. We enlarged the size of the ablation kill zone by infusing a 30-nm tumor necrosis factor-alpha and polyethylene glycol-coated gold nanoparticle (CYT-6091, CytImmune Sciences, Inc.) before ablation in a rabbit kidney tumor model.

The role of radiologic imaging and biopsy in renal tumor ablation.

Purpose: The rate of unintentionally discovered renal masses has been increasing along with a parallel increased incidence of renal cell carcinoma both in men and women. Ablation therapy has emerged as an alternative for the treatment of these small renal tumors. Several techniques have been developed for renal tumor ablation with cryoablation (CA) and radiofrequency ablation (RFA) being among the most widely used and studied.

Resorbable clip migration in the collecting system after laparoscopic partial nephrectomy.

A complication is reported in which Lapra-Ty absorbable suture clips (Ethicon EndoSurgery) migrated from a laparoscopic partial nephrectomy bed into the collecting system, causing renal colic. During surgery performed with hilar occlusion, visual inspection did not reveal collecting system entry. Transected vessels were oversewn with absorbable suture secured with Lapra-Tys.
