Laparoscopic donor nephrectomy versus open donor nephrectomy: Outcomes from a single transplant center.

Laparoscopic donor nephrectomy (LDN) is currently replacing open donor nephrectomy (ODN) across the world. Its advantages in terms of patient recovery are well known. We sought to compare surgical outcomes, particularly renal function during the post-nephrectomy period, for renal grafts procured by LDN versus ODN in our center.

The role of hemostatic agents in preventing complications in laparoscopic partial nephrectomy.

Introduction: Nephron-sparing surgery is currently the treatment of choice for renal cell carcinoma stage T1a. During the past years, several hemostatic agents (HA) have been developed in order to reduce surgical complications. We present the results of our series and the impact of the use of HA in the prevention of surgical complications in laparoscopic partial nephrectomies (LPNs).

Objetive: Our aim is to present a novel mutation of the Birt-Hogg-Dubé Syndrome.

Methods: We present a case report of a 70-year-old male with three solid nodulary lesions of 4, 2.6, and 3 cm each in the right kidney, and two lesions of 1.

Renal colic during pregnancy: Diagnostic and therapeutic aspects. Literature review.

Introduction: Renal colic during pregnancy is a rare urgency but is one of the most common non-obstetric reasons for hospital admission. The management often means a challenge for the urologist and gynecologist due to the complexity involved in preserving the maternal and fetal well-being.

Material And Methods: We performed a literature search within the PubMed database.

Current role of lymphadenectomy in the upper tract urothelial carcinoma.

Introduction: Lymphadenectomy (LND) has recently attracted considerable interest from urological surgeons, as extended lymphadenectomy might have a role in accurate staging or improving patient survival in those patients with urological malignancies. Upper tract urothelial carcinoma (UTUC) is a relatively rare neoplasm, accounting for about 5% of all urothelial cancers. Up to 30% of patients with muscle-invasive UTUC have metastasis in the regional lymph nodes (LNs), which represents a well-established poor prognostic factor.

Human native Ca1 channels in chromaffin cells: contribution to exocytosis and firing of spontaneous action potentials.

The present study was performed to evaluate the Ca1 channel subtypes expressed in human chromaffin cells and the role that these channels play in exocytosis and cell excitability. Here we show that human chromaffin cells obtained from organ donors express Ca1.2 and Ca1.

Laparoscopic radical cystectomy with prostate capsule sparing. Initial experience.

Introduction: In 2008, our department introduced a modified technique of laparoscopic radical cystectomy in which the prostatic capsule is spared in selected patients with bladder cancer. The different series published are mostly using the standard open procedure. The aim of this study is to describe this technique using the laparoscopic approach and present our preliminary results.

The role of perioperative blood transfusion on postoperative outcomes and overall survival in patients after laparoscopic radical cystectomy.

Introduction: There are different studies in the last decades focused on general surgery patients and the impact of perioperative blood transfusion (PBT) in cancer patients' survival, and most of them have supported an independent association between PBT and worse survival in those with solid tumor malignancies. The aim of this study is to evaluate the impact of perioperative blood transfusion on the postoperative outcomes and survival of patients after LRC.

Materials And Methods: We performed a retrospective study analyzing our series of 218 patients surgically treated with LRC form 2005 to 2012.

Evolution in the treatment of the ureteropelvic junction obstruction syndrome. Laparoscopic versus open pyeloplasty.

Introduction: The treatment of ureteropelvic junction has evolved considerably over the past 20 years, resulting in new surgical techniques, but traditional open surgery remains the gold standard treatment. Currently, less invasive techniques are used for the treatment of ureteropelvic junction obstruction. The purpose of our study is to compare the surgical and functional results between laparoscopic and open pyeloplasty performed at our department during the last 12 years.

Perioperative and survival outcomes of laparoscopic radical cystectomy for bladder cancer in patients over 70 years.

Introduction: Radical cystectomy in elderly patients is a controversial issue that has noticed an increase in importance overtime because of the lengthening average life span. Our objective was to determine if there were significant differences in the perioperative outcomes of patients over 70 years with bladder cancer treated with laparoscopic radical cystectomy (LRC) compared to those of younger patients.

Material And Methods: We selected 180 patients who underwent LRC in our department in the period between 2005-2012.

Laparoscopic radical prostatectomy training for residents: Hospital Universitario La Paz model.

Introduction: In the last decade, we have seen the advance of laparoscopic surgery in urology.All laparoscopic procedures in our department are performed by staff members and are assisted by a single resident, ensuring resident training in laparoscopic surgery. The aim of this study is to evaluate the results of the Hospital La Paz training program for residents in the field of laparoscopic surgery.

Renal function recovery after laparosocopic pyeloplasty.

Introduction: To observe the renal function recovery measured by diuretic renography in short and medium follow-up of patients with transperitoneal Anderson-Hynes laparoscopic pyeloplasty.

Material And Methods: WE PERFORMED A RETROSPECTIVE REVIEW FROM OUR SERIES OF LAPAROSCOPIC PYELOPLASTIES, AND WE APPLIED THE FOLLOWING SELECTION CRITERIA: 1) to have at least two MAG3 diuretic renography during the follow-up, performed with a gap of 4-6 months between them; 2) to have at least one year follow-up. Fulfilling these criteria, we have selected 35 patents of 62.

Approach to kidney stones associated with ureteropelvic junction obstruction during laparoscopic pyeloplasty.

Introduction: We have performed laparoscopic pyeloplasty (LP) in our department since 2004. Our goal is to describe, step by step, the approach of kidney stones during transperitoneal laparoscopic pyeloplasty and the outcomes after the procedure.

Material And Methods: Twelve patients with kidney stones treated by transperitoneal laparoscopic pyeloplasty were found.

Laparoscopic ureteral reimplantation in a renal transplant.

We present what is to our knowledge, the first case of laparoscopic ureteral reimplantation reported in the renal transplant. The ureteral stenosis is one of the most difficult renal transplant complications to deal with. With the development of the endourological approach, this treatment has become the first treatment option for these patients.

Transperitoneal laparoscopic pyeloplasty in the treatment of ureteropelvic junction obstruction.

Introduction: Laparoscopic pyeloplasty was first described by Schuessler. During the last decade, this technique has been developed in order to achieve the same results as open surgery, with lower rates of morbidity and complications. In this study we review our experience using laparoscopic pyeloplasty as the gold standard for the treatment of the ureteropelvic junction obstruction (UPJO).

Pharmacological characterization of native α7 nicotinic ACh receptors and their contribution to depolarization-elicited exocytosis in human chromaffin cells.

Background And Purpose: Expression of α7 nicotinic acetylcholine receptors (nAChRs) and their role in exocytosis have not yet been examined in human chromaffin cells.

Experimental Approach: To characterize these receptors and investigate their function, patch-clamp experiments were performed in human chromaffin cells from organ donors.

Key Results: The nicotinic current provoked by 300µM ACh in voltage-clamped cells was blocked by the nicotinic receptor antagonists α-bungarotoxin (α-Bgtx; 1µM; 6 ± 1.

Laparoscopic repair of the vesicovaginal fistula (laparoscopic O'Connor repair).

Introduction: The most frequent cause of vesicovaginal fistula in developed countries is hysterectomy, while in the third world it is related to time in labour. Any surgical iatrogenic trauma implies encountering added difficulties of various kinds when repairing the condition.

Material And Method: We report the first case of vesicovaginal fistula to be resolved laparoscopically in our department.

Laparoscopic transperitoneal radical prostatectomy in renal transplant recipients: a review of the literature.

Objectives: To report our experience with laparoscopic radical prostatectomy (LRP) for the treatment of localized prostate carcinoma in two renal transplant recipients and a review of the literature.

Patients And Methods: We retrospectively identified all patients who had undergone LRP for clinically localized prostate cancer between 2002 and 2008 at our institution (n = 1150). Of these patients, two were renal transplant recipients (one with donor renal transplant cadaver and the other with prior transplantectomy).

[Laparoscopic radical nephrectomy in big surgical specimens].

Introduction: The retroperitoneal surgery is the clearer indication for the laparoscopic approach. Still there are indications for open surgery because of the complexity of the patient and the surgeon experience.

Objectives: The main objective is to report our experience of laparoscopic radical nephrectomies in patient with tumors greater than 7 cm.

Impact of a clinical pathway in patient care following surgery on laparoscopic radical prostatectomy.

Purpose: The aim of this study was to evaluate the impact of clinical pathway (CP) implementation in laparoscopic radical prostatectomy (LRP) has had on patient care and clinical evolution after discharge.

Materials And Methods: Eighty-six patients were included in 2 groups: first group was composed of patients operated since the new technique (LRP) was used until the CP was implemented (26 patients operated in 2002) and, second group, with 60 patients, followed the CP during 2004 and 2005.

Results: The operative time was reduced from 377.

[Laparoscopic nephroureterectomy: new position for the management of distal ureter].

Objectives: The main challenge of laparoscopic nephroureterectomy is the management of distal ureter, which also will have an important repercussion in the oncological outcome of many cases. We present our experience in such aspect, considering that we performed the last five laparoscopic nephroureterectomies in forced Trendelemburg position, resulting in a more comfortable and safe management of the distal ureter.

Methods: Between August and December 2006 we performed five purely laparoscopic nephroureterectomies with bladder cuff positioning the patient in forced Trendelemburg, a position similar to that of laparoscopic radical cystectomy or prostatectomy.

[Bladder neurofibroma: case report and bibliographic review].

Objective: The prevalence of the disease is 1/3000 newborns; it is more frequent in men than in women with a 3:1 ratio in all races. Genitourinary tract neurofibromas usually arise from the pelvic and bladder nerves, and the prostatic plexus. Bladder is the most frequently affected organ of the urinary tract; bladder neurofibromatosis may present as a diffuse infiltrative process or an isolated neurofibroma.

[Ureteroenteric strictures: endourological treatment].

Objectives: To review the outcomes of the ureteroenteric strictures treated by endourological techniques in our department, and to compare our long-term results with other reported series with similar follow-up and number of patients.

Methods: We retrospectively reviewed 27 ureteroenteric strictures treated from March 1994 to June 2003, with a mean follow-up of 30.2 months (1 day-53 months).
