A case report of pudendal arteries angioplasty with sirolimus drug-coated balloon and drug-eluting stent associated with intracavernous autologous peripheral blood mononuclear cells injection for untreatable vasculogenic erectile dysfunction.

BACKGROUND: Erectile dysfunction (ED) is a prevalent health problem that seriously impacts men's quality of life. The potential treatment of ED by percutaneous approach has emerged with valid angiographic results and a significant improvement in symptoms and quality of life. In addition, cell-based regenerative therapies aiming at enhancing neovascularization have been successfully performed with peripheral blood mononuclear cells (PBMNCs) in diabetic patients affected by critical limb ischaemia. CASE SUMMARY: We report a case of a young insulin dependent (ID) diabetic patients who suffered of severe vasculogenic erectile dysfunction associated with a poor response for more than 1 year to oral phosphodiesterase-5 inhibitors (PDE5i) and intracavernous (IC) phosphodiesterase type 1 (PDE1) therapy. At selective angiography of the pelvic district, a severe atherosclerotic disease of the internal iliac and pudendal artery was evident with absence of distal vascularization of the cavernous bodies. The patient was treated by mechanical revascularization with drug-coated balloon and drug-eluting stent placement associated with IC injection of autologous PBMNCs. Immediate and 1-year clinical and angiographic follow-up are described. DISCUSSION: Percutaneous revascularization with drug-coated balloon and drug-eluting stent associated with IC autologous PBMNCs cells injection is a safe and effective procedure to restore normal erectile function in diabetic patients affected by severe vasculogenic ED not responding to conventional oral drug therapies.

Postoperative paralytic ileus after major oncological procedures in the enhanced recovery after surgery era: A population based analysis.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols have been developed and implemented as of 2001 and may have significantly reduced several complication types including paralytic ileus. However, no formal analyses targeted paralytic ileus rates after contemporary major surgical oncology procedures. We examined temporal trends of paralytic ileus following ten major oncological surgical procedures. The effect of paralytic ileus on length of stay (LOS) and total hospital charges was examined. Univariable and multivariable linear and logistic regression analyses were used. METHODS: Between 2003 and 2013, we retrospectively identified patients, who underwent prostatectomy, colectomy, cystectomy, mastectomy, gastrectomy, hysterectomy, nephrectomy, oophorectomy, lung resection or pancreatectomy within the Nationwide Inpatient Sample. A total of 3 431 602 patients were included in our analyses. Annual paralytic ileus rate differences after major oncological surgical procedures were evaluated using linear regression. Multivariable logistic regression analyses were used to test for paralytic ileus rates determinants, as well as on the effect of paralytic ileus rates on LOS and hospital charges. RESULTS: Paralytic ileus rates ranged from 0.1% (mastectomy) to 23.2% (cystectomy) after ten examined major oncological surgical procedures. Overall annual paralytic ileus rates did not change [estimated annual percentage change (EAPC)+0.1%, p = 0.7]. Multivariable logistic regression derived predicted probabilities (PP) of paralytic ileus were highest for cystectomy (PP: 26.1%) and colectomy (PP: 17.15%) and were lowest for lung resection (PP: 2.22%) and mastectomy (PP: 0.16%). In analyses predicting LOS above the 75th percentile, paralytic ileus effect after mastectomy (OR: 14.66) and prostatectomy (OR: 13.21) ranked, as highest and second highest respectively. In analyses predicting hospital charges above the 75th percentile, paralytic ileus effect after mastectomy (OR: 2.21) and oophorectomy (OR: 1.99) ranked as highest and second highest respectively. CONCLUSIONS: Despite implementation of ERAS protocols paralytic ileus rates have not decreased over time. Gastrointestinal procedures are among the highest contributors of paralytic ileus. Moreover, procedures with short LOS represent the strongest relative contributors to LOS increases and increases in hospitalization costs.

Feasibility and outcomes regarding open and laparoscopic radical prostatectomy in patients with previous synthetic mesh inguinal hernia repair: meta-analysis and systematic review of 7,497 patients.

INTRODUCTION: The purpose of this article is to contribute information to the interpretation of the feasibility and outcomes regarding open, laparoscopic and robotic strategies of radical prostatectomy in patients with previous synthetic mesh inguinal hernia repair. MATERIALS AND METHODS: A bibliographic search covering the period from January 1980 to September 2012 was conducted in PubMed, MEDLINE and EMBASE. Database searches yielded 28 references. This analysis is based on the eleven studies that fulfilled the predefined criteria. RESULTS: A total of 7,497 patients were included. In the study group, there were 462 patients. The surgical prostatectomy techniques were open in five studies, laparoscopic in three and robotic in the remaining three. The control group consisted in 7,035 patients. The comparison of the open procedure performed in patients with a previous mesh herniorrhaphy and controls shows that the number of lymph nodes removed resulted significantly lower and hospital stay with catheterization time results statistically longer. The comparison of the laparoscopic procedure does not evidence a statistically significant difference in terms of blood loss, operative time and catheterization time, while the comparison with the robotic group could not be performed for the lack of data. CONCLUSION: All patients need an adequate informed consent regarding the multitude of aspects which may be influenced by the mesh such as the possibility of hernia recurrence, mesh infection, need for mesh explantation, possibility of mesh erosion into the bowel or bladder, bladder neck contractures or postoperative urinary incontinence and a compromised nodal staging.

Is stone diameter a variable in the decision process of employing a ureteral stent in patients undergoing uncomplicated ureterorenoscopy and associated intracorporeal lithotripsy?

INTRODUCTION: A number of randomized trials and meta-analysis in patients who underwent ureteroscopic stone removal investigated the effects of placing a ureteral stent at the end of the procedure on complication rates. However, none of these investigates the stone diameter and its possible influence on complication rates and, as such, if it should be considered a possible variable in the decision process of placing or not a ureteral stent. MATERIALS AND METHODS: A bibliographic search covering the period from January 1990 to March 2012 was conducted in PubMed, MEDLINE and EMBASE. This analysis is based on the fifteen remaining studies which fulfilled the predefined inclusion criteria. All statistical evaluations were performed using SAS version 9.2. and by RevMan 5.0. RESULTS: A total of 1,416 patients were included. All the studies were published after 2000. Mean stone diameter ranged between 5.3 and 13.3 mm in the non-stented group and between 6.26 and 13.28 mm in the stented group. Meta-analysis showed that stone diameter was not statistically different for stented or non-stented subgroups, whereas surgical operative time was shorter for the non-stented subgroup. The effect of stone diameter, irrespectively if patients were operated with or without stents were grouped or considered separately, did not influence complications of fever, haematuria, unplanned medical visits after surgery and urinary tract infections. CONCLUSIONS: Stone diameter is not a variable in the pre- or intraoperative decision process of placing or not placing a ureteral stent in patients undergoing uncomplicated ureterorenoscopy with intracorporeal lithotripsy.

Urgent shock wave lithotripsy as first-line treatment for ureteral stones: a meta-analysis of 570 patients.

The rationale for the use of immediate shock wave lithotripsy (SWL) after a renal colic episode is to obtain maximum stone clearance in the shortest possible time with associated early detection of lithotripsy failures which can be treated with auxiliary procedures. The aim of this meta-analysis is to understand the role of this treatment option in the emergency setting as first-line treatment and to compare such an immediate procedure to a delayed one in terms of stone-free and complication rates. A bibliographic search covering the period from January 1995 to September 2010 was conducted in PubMed, MEDLINE and EMBASE. Database searches yielded 48 references. This analysis is based on the seven studies that fulfilled the predefined inclusion criteria. A total of 570 participants were included. The number of participants in each survey ranged from 16 to 200 (mean 81.42). Six studies were published after 2000 and one in the 1990s. All studies reported participants' age with mean of 40.9 years, and range between 11 and 88 years. All patients presented with unilateral lithiasis, as such the number of total stones treated was 570. Mean stone diameter ranged between 6.38 and 8.45 mm. According to the logistic regression applied stone-free rates were 79 % (61-95) for the proximal ureter, 78 % (69-88) for the mid ureter, 79 % (74-84) for the distal ureter and 78 % (75-82) for overall. Stone-free rates do not evidence a statistically significant difference compared to those described in the AUA and EAU guidelines for elective management. SWL management of ureteral stones in an emergency setting is completely lacking in the international guidelines and they results disperse in the literature in few works. According to our meta-analysis, immediate SWL for a stone-induced acute renal colic seems to be a safe treatment with high success rate. This evidence will be validated by further randomized studies, with a larger series of patients.

Urgent ureteroscopy as first-line treatment for ureteral stones: a meta-analysis of 681 patients.

There are various recent studies on the use of ureteroscopy and debate on whether this should be the first-line treatment for patients with ureteral stones. The aim of this meta-analysis was to understand the role of this surgical procedure in the emergency setting as first-line treatment and to compare the immediate procedure with a delayed one in terms of stone-free rate and complications. A bibliographic search covering the period from January 1980 to March 2010 was conducted in PubMed, MEDLINE and EMBASE. This analysis is based on the six studies found that fulfilled the predefined inclusion criteria. A total of 681 participants were included. The number of participants in each of the studies considered ranged from 27 to 244 (mean 113). Stone-free rates were 81.9% (72.0-91.8) for the proximal ureter, 87.3% (82.6-92.0) for the mid-ureter, 94.9% (92.1-97.6) for the distal ureter and 89.5% (86.5-92.5) overall according to the logistic regression applied. These values are not statistically significantly different from those reported in the AUA and EAU guidelines. The stone diameter seems to affect the stone-free rate. An increase of the stone diameter of 1 mm beyond 8 mm corresponded to a reduction of stone-free rate of 5% (2.4-8.0) and 8.1% (3.8-12.1) for the distal and proximal ureters, respectively. There is a complete lack of information in international guidelines on the ureteroscopic management of ureteral stones in an emergency setting and the currently available results are dispersed in a few studies in the literature. The rationale for using emergency ureteroscopy is more rapid stone clearance and relief from colic pain. According to our meta-analysis, immediate ureteroscopy for ureteral stone colic seems to be a safe treatment with a high success rate. This evidence will be validated by further randomized studies, with larger series of patients.

Endoscopic resection of bladder cancer in patients receiving double platelet antiaggregant therapy.

BACKGROUND: Approximately 5% of patients who have undergone coronary artery stenting require noncardiac surgery within a year of their cardiac intervention. European cardiological guidelines and recommendations from the U.S. Food and Drug Administration on platelet antiaggregant therapy following coronary artery stenting are for dual treatment with acetylsalicylic acid and clopidogrel, which should be continued for at least 12 months. The aim of this study was to evaluate the clinical course in patients receiving double platelet antiaggregant therapy who underwent transurethral resection of bladder cancer. METHODS: Between September 2007 and April 2010, twelve patients receiving double antithrombotic therapy (clopidogrel+acetylsalicylic acid) underwent transurethral resection of bladder cancer. In two cases the operation was "urgent". The mean age of the patients was 71.25 years (range, 52-83 years). In nine cases the bladder cancer was newly diagnosed. RESULTS: The patients' preoperative mean hemoglobin concentration was 11.4 g/dl (range=5.2-13.4 g/dl), and on the first postoperative day it was 10.2 g/dl (range=9.6-12.6 g/dl). The mean duration of the intervention was 32 min (range=20-60 min). There were no cardiac complications in either the perioperative or the postoperative period. No patient required reintervention for hemostatic purposes. Three episodes of clot-related acute urinary retention occurred after removal of the bladder catheter, all of which were resolved with replacement of the catheter without needing reintervention. CONCLUSION: Despite the high number of complications related to cardiac problems that suspension of these drugs causes, this urological intervention, carried out during dual antithrombotic therapy, was feasible and without major complications. Given the high proportion of complications due to clot-related urinary retention, it is advisable to leave the urinary catheter in place for a longer period.

[The use of temporary stents in the treatment of urethral stenosis]. / Considerazioni sull'utilizzo degli stent temporanei nel trattamento delle stenosi uretrali.

The Authors report their past experience in the treatment of urethral strictures by means of temporary stent implants (Urocoil). The results at a long-term follow-up were poor in strictures of the bulbous and penile urethra (2/19 at 36 months) and very good in strictures of bladder neck and prostatic urethra (10/10 at 45 months). They conclude that this treatment has been at present abandoned due to high costs and poor results. It could however be effective in the treatment of postsurgical bladder neck strictures recurring after endoscopic treatment.
