Traumatic rupture of the corpus cavernosum: surgical management and clinical outcomes. A 30 years review

Introduction Penile trauma (PT) with associated rupture of the corpus cavernosum, also called penile fracture, is a urological emergency and surgical treatment is usually the choice of management. Our objective is to report our experience after 30 years in the diagnosis and therapeutic options of PT and evaluate the clinical outcomes after the treatment. Material and methods From January 1983 to January 2013, 27 patients were identified. Data was analyzed and is presented in absolute numbers, range, percentage and mean. Results Mean age of patients was 30.7 years, range from 19 to 37. All the patients came complaining of penile swelling and hematoma, and more than half of them (60.7%) reported hearing a snap sound. Some rare causes were identified in our series such as self–mutilation, avulsion, firearm and electrocution. Clinical presentation was diagnostic in all the patients, and the diagnosis was verified by penile ultrasonography in most cases (60.7%). Mean surgery time: 94 minutes. Urethral repair was required in 2 patients. Mean hospital stay was 2 days. Good functional results are shown during follow up. Conclusions Rupture of the corpus cavernosum is a rare condition and is generally diagnosed by clinical findings. Emergency surgical exploration and treatment is the best guarantee of good functional and cosmetic results.

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. We divided them into 2 groups: 57% <70 years and 43% >70 years, and we compared the different parameters such as: comorbidities, intraoperative and post-operative complications, TNM stage and overall survival. Results The group <70 years had less comorbidities when compared with the group >70 years. Heterotopic urinary diversion was the diversion of choice in the elderly patients (97.4%). Paralytic ileus and the worsening of renal function were the only complications with statistical differences between the groups. Mean hospital length of stay was not significantly different between the groups. Younger and older patients had similar pathological staging : pT1 or less: 26,2 vs. 18.2%, pT2: 19.4 vs. 16.9%, pT3 38.8 vs. 37.7% and pT4 15.6 vs. 17.2%. Kaplan-Meier curves did not show significant differences in survival. Conclusions Laparoscopic radical cystectomy in the elderly patient has similar rates of perioperative morbidity when compared with the younger patient and may be offered as a treatment option in selected elderly patients.

Implante de balones parauretrales como tratamiento de la incontinencia urinaria masculina: Experiencia del Hospital Universitario La Paz

OBJETIVOS Queremos expresar nuestra experiencia con el implante de balones parauretrales, como tratamiento de la incontinencia urinaria masculina. METODOS Hemos revisado de forma retrospectiva nuestra serie desde marzo del 2003 a marzo del 2007, que incluye a 69 pacientes con incontinencia urinaria masculina, la mayoria tras prostatectomia radical. RESULTADOS 6 pacientes estan pendientes de su primera revision tras la cirugia. Con un seguimiento medio de 22 meses (3-48) el 57.14% de los pacientes (36/63) no precisan proteccion y el 12.69% usan una compresa de seguridad (8/63), por tanto el 69.83% (44/63) de los pacientes estan secos o usan una compresa de seguridad. Si estratificamos a los pacientes segun el grado de su incontinencia, el 81,25% de los pacientes con incontinencia leve estan secos y el 59.25% de los pacientes en el grupo de incontinencia moderada. Sin embargo, solo el 35% de los pacientes con incontinencia severa estan secos (sin proteccion). CONCLUSIONES Segun nuestra experiencia, pensamos que el implante de balones parauretrales podria ser la primera opcion terapeutica para la incontinencia urinaria masculina leve y moderada.

Tumor adenomatoide de epidídimo e intratesticular: a propósito de nueve casos clínicos y revisión de la literatura

OBJETIVO: Describir los casos de tumores adenomatoides del Hospital Universitario La Paz en los ultimos 15 anos. METODOS: Se ha realizado estudio clinico, anatomopatologico y quirurgico de los varones con tumoracion testicular o paratesticular con resultado histologico de tumor adenomatoide. RESULTADOS: En total hay nueve casos; siete presentaron tumor adenomatoide de localizacion paratesticular y dos intratesticular. La exeresis de la masa fue el tratamiento de eleccion en los epididimarios y orquiectomia en los intratesticulares. CONCLUSIONES: Los tumores adenomatoides son neoplasias benignas, poco frecuentes, de posible origen mesotelial. Como consecuencia de su naturaleza benigna, el tratamiento de eleccion es la exeresis local (cirugia conservadora), aunque en dos casos se llevo a cabo orquiectomia debido a su localizacion.

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. Material and methods We have done a retrospective review of LRP performed by the residents in our department. We also evaluated different variables. Descriptive statistical analysis was done and the results were compared with the descriptive analysis of the initial series of our department. Results We reviewed 82 patients, with an average age of 61.6 years. Most cases were pT1c at diagnosis. Average surgical time was 288 minutes, with a transfusion rate of 9.7% and a intra and postoperative complication rates of 1.2% and 7.3%. The mean hospital stay was 3.3 days. Histological results of this series are: 76.8% of pT2 and 23.2% of pT3. The biochemical relapse rate is 15.8%. Global surgical margin rate is 20.7%. The global continence rate is 52.4%. Conclusions The outcomes of LRP performed by residents are similar to the ones reported in the initial series of our department. The fact that 84.6% of the residents formed in this period actually belong to different laparoscopic units supports the success of La Paz Hospital training model.

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). Material and methods We performed a retrospective review of 62 laparoscopic pyeloplasties carried out at our center. In the last 2 years we used 3 mm and 5 mm ports in order to achieve better cosmetics results. Demographic data is described and the functionality of the affected kidney and surgical data, among others were analyzed statistically. In the case of bilateral statistical tests were considered significant as those with p values <0.05. Results The most frequent reason for consultation was ureteral pain. Patients mean age was 40 years and 94% of them had preoperative renogram showing a full or partial obstructive pattern. The right side was affected in 61% of cases and the left in the remaining 39%. The presence of stones was observed in 12 patients and crossing vessels in 58% of cases. The average stay was 3.72 days. Post–surgery complications were observed in two patients. The operative time was 178 minutes. Mean follow–up was 45 months and a success was achieved in 91%. Conclusions The transperitoneal laparoscopic pyeloplasty has become the gold standard for the treatment of ureteropelvic junction stenosis in our center because of high success rate, shorter postoperative stay, and low intra and postoperative complications.

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. Material and methods This is a retrospective review of 92 cases performed in a period of 12 years. Two groups were compared: 30 patients were treated with open surgery (OP) and 62 with a laparoscopic approach (LP). Demographics, clinical presentation, functionality of the affected kidney, presence of polar vessels, kidney stones, hospital stay, complications and functional results were statistically analyzed. Results The mean age was 42 years. The most common clinical presentation was kidney or ureteral pain: 60% (OP) vs. 52% (LP). The right side was affected in 59%; presence of crossing vessels was 47% (OP) vs. 58% (LP); presence of kidney stones was 20% (OP) vs. 19% (LP), with an average hospital stay of 5.86 days (OP) vs. 3.36 days (LP) p <0.05. Post-operative complications were observed in 3 (OP) vs. 5 (LP) patients, with a success rate comparable between groups. Conclusions In our department, we recommend LP as the standard treatment for ureteropelvic junction obstruction because of the equal success rate compared to OP and the benefits of a minimally invasive 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. Results During follow–up, statistically significant improvement comparing with the pre–surgical value has been observed in diuretic renography in the operated kidney in all selected patients during the time of follow up in terms of: functional uptake ratio (FUR), furosemide excretion and total excretion. No statistically significant differences were found in excretion time and spontaneous excretion parameters. By dividing patients in two age groups <40 years and >40 years we found no statistically significant differences between them in relation to the improvement of the FUR. Conclusions Laparoscopic pyeloplasty not only corrects the UPJO, it also may recover renal function demonstrated after one year follow up with diuretic renography. Laparoscopic pyeloplasty should be procedure of choice even in those patients with poor renal function at diagnosis, whenever there are chances of recovering renal function, regardless patients age.

Balones parauretrales (Pro-ACT TM) en la incontinencia urinaria postquirúrgica del cáncer de próstata

OBJECTIVES Prostate cancer early detection campaigns have led to the diagnosis of a greater number of patients with organ-confined disease candidates for intention-to-cure treatment. Radical prostatectomy is one of these treatments; despite the technical advances with the development of laparoscopic or robotic operations it still has urine incontinence as a side effect affecting patients quality of life. METHODS/RESULTS Based on the experience in the Urology Department at Hospital La Paz we describe the technique and our results, comparing with a bibliographic review of other techniques used for the treatment of urinary incontinence after radical prostatectomy from the Medline database. CONCLUSIONS The insertion of the paraurethral ProACT is the treatment of choice for mild-moderate incontinence after radical prostatectomy in our environment due to its high success rate and low morbidity, technical easiness, and adequate cost and resources requirements.

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. The patient is a 28-year-old female who received a renal allograft from a cadaver donor in 2008. Ureteral stenosis was diagnosed. The laparoscopic approach seems to be a good option over the open approach, with the benefits related with laparoscopic surgery.
