Supine mini percutaneous nephrolithotomy in horseshoe kidney.

Objective: The percutaneous nephrolithotomy (PCNL) in Horseshoe kidneys (HSK) is usually performed in the prone position, allowing entry through the upper pole and providing good access to the collecting system. However, in patients with normal kidney anatomy, the supine position is reliable and safe in most cases, but it is unknown whether the supine position is adequate in patients with HSK. The purpose of this study was to describe the results of PCNL in HSK in three different surgical institutions and to evaluate the impact of supine position during surgery, comparing pre-operative and post-operative data, complications, and stone status after surgery.

Stone free rate and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS): Our experience in 571 consecutive cases.

Introduction: The purpose of this study is to report the stone free rate (SFR) and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS).

Materials And Methods: A total of 571 procedures of upper urinary stones treated using flexible ureteroscopy and holmium laser lithotripsy from January 2014 to February 2020 have been analyzed. Overall SFR was evaluated after 3 months following the procedure by means of a non-contrast computed tomography.

UVENTA urethral stents: Are we taking a step forward? The first clinical series.

Objectives: To describe first clinical results in term of safety, complications and short term efficacy of temporary placement of UVENTA urethral stent in the treatment of urethral and bladder neck strictures.

Methods: UVENTA urethral stent (Taewoong Medical) is a temporary self expandable covered metallic stent. Anti-migration system and different radial force distribution are the two main innovations.

Flexible ureteroscopy using a 120-w holmium laser: The low-energy/high-frequency approach.

With the spread of more powerful lasers and the advent of new technologies, endoscopic interventions for urolithiasis are continuously evolving. The aim of this study is to present our experience and technique regarding Low Energy (LE)/High Frequency (HF) lithotripsy by using a 120-W Holmium laser (Lumenis®). METHODS: We retrospectively analysed our prospectively maintained Retrograde Intra Renal Surgery (RIRS) database.

Percutaneous Nephrolithotomy in Horseshoe Kidneys: Results of a Multicentric Study.

To report the outcomes of percutaneous nephrolithotomy (PCNL) in horseshoe kidneys (HSK) in 12 institutions worldwide and evaluate the impact of patient position during operation. We carried out a retrospective analysis of PCNL procedures performed between 2008 and 2018 in patients with HSK. Pre-, peri-, and postoperative data were collected, and a subgroup analysis was performed according to patient position.

Life-threatening complications after ureteroscopy for urinary stones: survey and systematic literature review.

Introduction: Retrograde ureteroscopy (URS) has become a common procedure for the management of urinary stones. Although its efficacy and safety are well known, the literature about major complications is still poor. This study highlighted some cases of life-threatening complications after semi-rigid ureteroscopy (s-URS) or flexible ureteroscopy (f-URS).

Prostatic artery embolization in benign prostatic hyperplasia: preliminary results in 13 patients.

Aim: The aim of the paper is to report the clinical outcome after prostatic artery embolisation (PAE) in 13 consecutive patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).

Materials And Methods: From May 2012 to October 2013, we performed PAE in 13 consecutive patients (mean age 75.9 years) with BPH and LUTS and refractory to medical therapy; seven patients had an indwelling bladder catheter.

Corporoplasty by plication: out patient surgery for the correction of penile curvature.

Objective: Corporoplasty using plication of the albuginea is a simple technique but considered by many Authors at high risk for recurrence in respect to other corrective techniques using excision of the albuginea tunica. The aim of this study was to assess long-term functional and cosmetic results of this approach done in an outpatient environment.

Material And Methods: From January 1997 to December 2008 we submitted 217 patients presenting induratio penis plastica (183) or congenital curvature (34) to corporoplasty with albuginea plication.

PSA repeatedly fluctuating levels are reassuring enough to avoid biopsy?

Introduction: Prostate-specific antigen (PSA) levels can show wide fluctuations when repeatedly measured. Here we investigatewd if: (a) biopsy timing influences the prostate cancer (PC) detection rate in patients with fluctuating PSA (flu-PSA) in comparison with patients with steadily increasing PSA (si-PSA); (b) PSA slope estimated in patients with flu-PSA predicts a different risk of cancer detection; (c) flu-PSA and si-PSA patients develop PC in topographically different sites; (d) the behaviour of pre-operative PSA is an expression of a disease with defferent characteristics to the following radical prostatectomy.

Methods: The study involved 211 patients who underwent at least a second biopsy after a first negative prostate biopsy.

Tubeless percutaneous nephrolithotomy: Our experience.

Purpose: To evaluate safety and outcomes of tubeless PCNL in comparison with standard PCNL.

Materials And Methods: Since June 2002 we have performed 99 tubeless PCNL. Tubeless technique involves antegrade placement of a 6Fr double-J stent without nephrostomy tube at the end of the procedure.

Percutaneous nephrolithotomy: tubeless or not tubeless?

The objective of this study is to evaluate the safety and outcomes of tubeless PCNL in comparison with standard PCNL. Since June 2002, we have performed 99 tubeless PCNL. Tubeless technique involves antegrade placement of a 6Fr double-J stent without nephrostomy tube at the end of the procedure.

Incidence and treatment of complications in nephron sparing surgery.

Unlabelled: Conservative renal surgery (enucleation or segmentary resection) has become the gold standard treatment for small and peripheral malignant kidney lesions or in cases of reduced renal function or bilateral lesions. The aim of this study is to evaluate the incidence and treatment of complications of this technique in our experience.

Materials And Methods: Between March 1997 and March 2005, 159 patients aged from 23 to 77 years (median 66 years) underwent conservative renal surgery.

Retropubic nerve and seminal sparing radical prostatectomy for recurrent bladder neck-prostatic urethra strictures.

Objectives: To verify if nerve and seminal sparing radical prostatectomy could represent surgical solution for iatrogenic bladder neck prostatic urethra contracture without external sphincter involvement.

Material And Methods: At our institution 4 patients have been submitted to nerve and seminal sparing radical prostatectomy for recurrent bladder neck-prostatic urethra contracture following TURP for middle size adenoma. In all cases bladder neck was reconstructed and a 20F silicon catheter was left in place for two weeks to stint the vesico-urethral anastomosis.
