Ultramini-percutaneous nephrolithotomy versus retrograde intrarenal surgery in the treatment of 10-30 mm calculi: a randomized controlled trial.

The surgical management of renal stones 10-30 mm is usually performed with percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS). Standard form of percutaneous nephrolithotomy has paved the way for miniaturized PCNL in many centres. We wanted to evaluate the efficacy, safety and the cost-effectiveness of ultramini-percutaneous nephrolithotomy (UMP) versus RIRS in the treatment of renal stones with stone burden 10-30 mm.

Mini Percutaneous Kidney Stone Removal: Applicable Technologies.

Percutaneous nephrolithotomy (PCNL) remains the treatment of choice for large and complex renal stones. The technological advances over the past several decades gave birth to different varieties of minimally invasive PCNLs, including the mini-PCNL, ultra-mini PCNL, super mini-PCNL, and micro-PCNL, with indications being extended to stones even larger than 20 mm. This article provides an update of all these available techniques of miniaturized PCNL along with its anatomic and physiologic impact.

European Association of Urology Section of Urolithiasis and International Alliance of Urolithiasis Joint Consensus on Percutaneous Nephrolithotomy.

Context: Although percutaneous nephrolithotomy (PCNL) has been performed for decades and has gone through many refinements, there are still concerns regarding its more widespread utilization because of the long learning curve and the potential risk of severe complications. Many technical details are not included in the guidelines because of their nature and research protocol.

Objective: To achieve an expert consensus viewpoint on PCNL indications, preoperative patient preparation, surgical strategy, management and prevention of severe complications, postoperative management, and follow-up.

Classification and standardized reporting of percutaneous nephrolithotomy (PCNL): International Alliance of Urolithiasis (IAU) Consensus Statements.

Background: The aim of this study was to reach a consensus in the classification and standardized reporting for the different types of PCNLs.

Methods: The RAND/UCLA appropriateness methodology was used to reach a consensus. Thirty-two statements were formulated reviewing the literature on guidelines and consensus on PCNLs, and included procedure specific details, outcome measurements and a classification for PCNLs.

Prospective outcomes of 11-13Ch. ultra-mini percutaneous nephrolithotomy (UMP): A consecutive cohort study.

Unlabelled: Ultra mini PCNL (UMP) has been described as a less invasive technique of PCNL for the treatment of small to medium sized stones in attempt to reduce the surgical morbidity.

Objective: Evaluate prospectively the outcomes of UMP.

Methods: Single surgeon prospective concurrent cohort study of UMP in India.

Ultra-mini PNL (UMP): Material, indications, technique, advantages and results.

Stone disease has afflicted mankind since centuries; records from ancient civilisations of India and Egypt have shown stones in human bodies. The scientific mind of humans has always made smart endeavours to remove the kidney stones. From large instruments made like the beaks of different animals and birds in 600 BC (Indian civilisation) to extremely sophisticated and miniaturised endoscopic intruments of today the human race has travelled a long way.

Percutaneous nephrolithotomy: technique.

Percutaneous nephrolithotomy (PCNL) is considered to be the first line of treatment for large renal stones. Though PCNL comes with higher morbidity, its efficacy is unbeaten by other minimally invasive modalities. However, potential complications, such as bleeding, occur.

Prospective Outcomes of Ultra Mini Percutaneous Nephrolithotomy: A Consecutive Cohort Study.

Purpose: Ultra mini percutaneous nephrolithotomy is a less invasive technique of percutaneous nephrolithotomy to treat small to medium sized calculi.

Materials And Methods: We prospectively evaluated the outcomes of ultra mini percutaneous nephrolithotomy in a single surgeon, consecutive cohort study. Data on 94 patients who underwent ultra mini percutaneous nephrolithotomy were collected.

Ultra-mini PCNL versus flexible ureteroscopy: a matched analysis of treatment costs (endoscopes and disposables) in patients with renal stones 10-20 mm.

Purpose: Latest publications state equal efficacy of a recently introduced new percutaneous technique ("ultra-mini PCNL", UMP) and flexible ureteroscopy (fURS) in the treatment of medium-size urinary stones. Today we face challenges concerning cost-effectiveness and reduction of in-hospital length of stay. In this retrospective study, we compare clinical outcome parameters and costs of treatment (endoscopes and disposables) of both techniques.

Non urothelial bladder cancers: a case series.

Non urothelial bladder cancers frequently present a diagnostic and therapeutic challenge. The article presents a case series of 21 patients of non urothelial urinary bladder cancers presented in our institute over a period of three years and review of literature on this rare condition. Details of patients were reviewed from hospital records of surgical, medical, radiotherapy and pathology departments.

A novel technique of ultra-mini-percutaneous nephrolithotomy: introduction and an initial experience for treatment of upper urinary calculi less than 2 cm.

Objectives: To describe our novel modified technique of ultra-mini-percutaneous nephrolithotomy (UMP) using of a novel 6 Fr mininephroscope through an 11-13 Fr metal sheath to perform holmium: YAG laser lithotripsy.

Methods: The medical records of 36 patients with moderate-sized (<20 mm) kidney stones treated with UMP from April to July 2012 were retrospectively reviewed. Patients were assessed at the 1st day and 1st month postoperatively by KUB and US to assess stone-free status.

Ultra-mini percutaneous nephrolithotomy (UMP): one more armamentarium.

Objective: To describe our newly developed technique for the removal of renal stones, which we have called ultra-mini percutaneous nephrolithotomy (UMP).

Methods: UMP was performed in 62 patients using a 3.5-F ultra-thin telescope and specially designed inner and outer sheaths.
