[Laparoscopic radical cystectomy and orthotopic urinary diversion in the male patient: technique]. / Técnica de cistectomía radical laparoscópica y derivación urinaria ortotópica en el varón.

Radical cystectomy with extended pelvic lymphadenectomy remains the treatment of choice for muscle invasive bladder cancer and non-metastatic chorion-invasive high grade tumors resistant to treatment with intravesical chemotherapy. During the last decade the procedure has been refined and we have acquired the skills necessary to perform it using the laparoscopic approach. In this way, the oncologic and functional outcomes obtained can be compared to those of its open counterpart. This article describes in detail the technique of radical cystoprostatectomy and urinary diversion in the male patient conducted by our group in an attempt to improve the knowledge and spread of this always difficult procedure.

Salvage lymph node dissection in patients with prostate cancer treated with radical prostatectomy or radiotherapy and positive choline positron emission tomography (PET/CT) scan. / Linfadenectomía de rescate en pacientes con cáncer de próstata tratados con prostatectomía radical o radioterapia y tomografía por emisión de positrones (PET) con colina positiva.

INTRODUCTION AND OBJECTIVES: Nodal prostate cancer recurrence is a challenging scenario. Current guidelines recommend the use of androgen deprivation therapy, tailored treatment or clinical trials. We studied the impact of Salvage lymph node dissection in selected patients. MATERIAL AND METHODS: We retrospectively reviewed records of 23 consecutive patients with prostate cancer and previous Radical prostatectomy or Radiotherapy who underwent SLND from December 2005 to November 2015. RESULTS: We found that in patients that showed biochemical response the introduction of ADT was delayed 14.9 months compared to patients that did not responded (2.8 months) P=.00026. Furthermore although statistical significance was not reached (P=.072) PSA-DT could be a potential prognostic factor of radiological recurrence since patients with PSA-DT<6 months developed radiological recurrence 7.6 months earlier compared to their counterparts. CONCLUSIONS: Salvage lymph node dissection is a potential treatment that could delay ADT in selected patients.

[Laparoscopic radical cystectomy: initial experience]. / Cistectomía radical laparoscópica: experiencia inicial.

OBJECTIVE: To review our initial experience with laparoscopic radical cystectomy. PATIENTS AND METHODS: Between September 2004 and June 2006 we performed 16 laparoscopic radical cystectomies (14 males and 2 females) with a median age of 63.8 y.o. (51-85). 12 ileal neobladder (with laparoscopic ileal-urethra anastomosis), 3 cutaneous ureteroileostomies and 1 cutaneous ureterostomy were performed as derivation techniques. Median follow up was 12.4 months RESULTS: Mean operation time was 340 minutes. Estimated blood loss was 350 ml. and 3 cases required intra-op blood transfusion. Mean hospitalization discharged was at 7.6 days. Median linph node dissection was 22.9 finding node metastasis in 6 cases. Most frequent complication was ileo in two cases. No local recurrentes in trocar placement was achieved. CONCLUSIONS: Laparoscopic Radical cystectomy is a challenged long-lasting procedure but with the advantage of a less transfusion rate and short hospital stay. Oncologycal outcomes are similar as tose from open surgery.

[Laparoscopic augmentation enterocystoplasty: initial experience]. / Enterocistoplastia de ampliación laparoscópica: experiencia inicial.

OBJECTIVE: To analyze the initial experience of our group in the realization of the augmentation enterocystoplasty by laparoscopyc approach. METHODS AND PATIENTS: We describe the augmentation enterocystoplasty technique with ileal segment completely achieved by laparoscopyc approach. We present the cases of two patients suffering from hyperreflexic bladder refractory to medical treatment who underwent this surgery. In both cases the technique was realized without intraoperative complications although it was needed a surgical time of 6 and 4.5 hours respectively. The results after 12 and 5 months were satisfactory in both patients, obtaining a low pressure bladder with a good continence. CONCLUSIONS: Laparoscopyc augmentation enterocystoplasty is a complicated technique that requires a great experience, mainly in laparoscopyc suture. It reproduces completely the open surgery and it offers all the advantages inherent to the laparoscopyc surgery.

A comparative study between open and laparoscopic approach in radical cystectomy with orthotopic ileal neobladder.

OBJECTIVE: Probably, laparoscopic radical cystectomy with ileal neobladder and neovesicourethral anastomosis is one of the most complex procedures in minimally invasive surgery. MATERIAL AND METHODS: Prospective study carried out in 72 patients surgically treated for invasive bladder neoplasia between January 2008 and October 2013. Patients were undergone to radical cystectomy with ileal neobladder (open approach in 33 patients and laparoscopic approach in 39). The study assessed comparatively surgical outcomes, continence rate and postoperative complications. RESULTS: Mean age was 63.5±9 years (64.3 open vs. 62.7 laparoscopic, P=.46) mean surgery time 323.6±78.7 minutes (321.3 vs. 326.5, P=.77), average hospital stay 14.8 days±8,1 (16.2 vs. 13.6, P=.2), transfusion rate 40.3% (66.7% vs. 17.9%, P<.0001) and complications rate 47.2% (63.6% vs. 33.3%, P=.01). Major complications were reported in 29.1% of cases (39.4% open vs. 20,5% laparoscopic, P=.07). With a mean follow-up rate of 42.5±19.2 months (range 15-70), 50 (69.4%) patients remain alive and free of disease. Continence was evaluated in these patients: total continence rate was 38% (50% vs. 27%, P=.09) and diurnal continence rate 58% (70.8% vs. 46.1%, P=.07). Self-catheterization rate was 8% (4.2% vs. 11.5%, P=.67). Total incontinence rate was 34% (25% vs. 42.3%, P=.19). CONCLUSION: According to our experience, transfusion rate, number and severity of complications are lower in laparoscopic cystectomy with ileal neobladder. No statistically significant impact on operative time and on hospital stay was observed. In patients undergone to laparoscopic approach, continence rate is lower but not statistically significant.

[Percutaneous endourologic treatment of obstructive ureteral lithiasis in renal transplant]. / Tratamiento endourológico percutáneo de litiasis ureteral obstructiva en injerto renal.

Donor graft lithiasis is a unusual complication of renal transplantation, however, it is associated to a high morbidity. This pathology is due to several causes such us: metabolic factors, infectious disease, drugs, foreign bodies or transferred in the donor graft. The objective of the treatment is to remove the lithiasis without damaging the renal unit. We report the successful percutaneous anterograde treatment of an ureteral obstructive hard calculi, in renal allograft.

[Genital autoaggression. An unusual presentation]. / Autoagresión genital. Una forma de presentación poco habitual.

Self-injuries are relatively common and usually consist in incisive injuries on the penis and the scrotum. This paper presents one case of genital self-injury by injection of petrol on the back of the penis. A description is offered of the clinical form of presentation, as well as the good evolution following medical treatment. Finally, a revision of likely complications is included.

[Iatrogenic injury of the lumbar ureter and iliac vessels after lumbar discectomy: urologic treatment using kidney autotransplantation]. / Lesión iatrogénica de uréter lumbar y vasos ilíacos tras discectomía lumbar: tratamiento urológico mediante autotrasplante renal.

We report a case of a patient with a secondary injury of external iliac artery and vein in the L4-L5 laminectomy and discectomy course. An immediately vein suture and ilio-iliac by-pass with Dacron was made. In the postoperative a iatrogenic lumbar ureter section was discovered and treated with renal autotransplantation. We review the options described in the literature in the management of these complex ureteral injuries.

[Use of intrarectal lidocaine gel in ultrasound-guided transrectal biopsies of the prostate]. / Uso de gel de lidocaína intrarectal en las biopsias transrectales ecodirigidas de próstata.

OBJECTIVE: To know in a quantitative manner the degree of discomfort and pain of the biopsies of the prostate and to evaluate the effectiveness of the transrectal lidocaine. MATERIAL AND METHOD: We performed 140 transrectal biopsies of the prostate, Patients were included on a random basis into two arms: one of them received intrarectal lidocaine, 20 mg (group 1, n = 71) and the other group received placebo (group 2, n = 28) both of them ten minutes prior the proceeding. RESULTS: The global pain mean was 3.7 (0 no pain, 10 highest pain) and the global discomfort mean was 3.5. The group 1 patients showed a trend to feel less pain and discomfort although it did not reach the necessary statistic significance (p = 0.7 y p = 0.5 respectively). CONCLUSIONS: We do not achieve the good results obtained by other groups in order to decrease the degree of pain and discomfort with the use of intrarectal lidocaine. We did not find relationship between the PSA level, previous biopsies, intrarectal lidocaina and degree of information received and the degree of pain and discomfort.

Utility of Histoscanning™ prior to prostate biopsy for the diagnosis of prostate adenocarcinoma.

OBJECTIVES: HistoScanning™ (HS) is a method of ecographic diagnosis of prostate cancer. We analyze the effectiveness of the HS realization prior to the biopsies for the prostate adenocarcinoma diagnosis. MATERIAL AND METHODS: From August to October 2012 we have carried out a study with HS prior to the biopsies in 32 patients. In all cases sextants transrectal biopsies have been realized (two cores in each sextant) in the periphery zone. In those sextants in which there were suspicious areas with HS, the biopsies were addressed to those areas. Transperineal biopsies were added to those zones placed in the half-front or apical prostatic zone. The medium age was 63.7 years (range 40-82) with a medium PSA of 8.0 ng/ml (range 3.5-36.2) and a medium prostatic volume of 46.6cc (range 18.2-103.2). In eight cases it was the first biopsy, in 14 cases they were repetition biopsies and 10 patients had a previous diagnosis of prostate adenocarcinoma (8 in a program of active surveillance and 2 T1a in RTU of previous prostate). RESULTS: In the 32 patients a medium of 7,5 zones were biopsied (range 6-9) with a total of 239 zones studied. There were identified a medium of 3.2 zones with suspicious areas (ZS) with HS (range 2-5) with a total of 103 ZS. In 72 zones of 25 patients it was found adenocarcinoma or PIN (2 PIN, 11 score Gleason 6, 7 score Gleason 7, 3 score Gleason 8 and 2 score Gleason 9). There were 35 positive false zones in 20 patients (11 normal parenquima and 9 chronic inflammation). Negative falses were produced in 5 zones in 5 patients (2PIN, 2 score Gleason 6 and 1 score Gleason 7) although in all 5 cases adenocarcinoma was encountered (o discovered) in other zones. The HS presented a sensibility of a 93.5% with a specificity of 79.5%. The positive predictive value was of the 67.35% with a negative predictive value of 96.5%. CONCLUSIONS: In spite of being a selected serie, with a high rate of patients with adenocarcinoma, the exploration with HS has presented a great sensibility and a high negative predictive value. These data, although they must be confirmed in less selected series, state that the prior exploration with HS can help as in the diagnostic in the biopsies as in the follow-up of programs of active surveillance.

[Vesiculectomy with laparoscopic partial prostatectomy in the treatment of primary adenocarcinoma of the seminal vesicle with carcinomatous transformation of the ejaculatory duct]. / Vesiculectomía con prostatectomía parcial laparoscópica en el tratamiento del adenocarcinoma primario de vesícula seminal con transformación carcinomatosa del conducto eyaculador.

INTRODUCTION: Primary adenocarcinoma of the seminal vesicle is an extremely rare condition. Some cases have been described in relation to congenital seminal vesicle cysts, which is often also associated with agenesia or ipsilateral renal disgenesia. The rareness of this type of lesions makes it difficult to plan a regulated surgical approach for them, although they are often treated by simple exeresis or exenteration, depending on their stage at the beginning. MATERIALS AND METHODS: We present a new surgical technique that consists of radical vesiculectomy associated with laparoscopic partial prostatectomy (total segmentary) of the central area to successfully treat primary seminal vesicle adenocarcinoma in a young man who was diagnosed through an azoospermia study. RESULTS: A study of the scan (MRI) with diffusion and the transrectal biopsy of the mass allowed us to make a thorough preoperative evaluation of the case, confirming the malignity and precociousness of the lesion. The laparoscopic approach allowed us to perform a pelvic lymphadenectomy and transperitoneal exeresis, including the central prostate area and suture of the posterior face of the urethra at the height of the apex of the prostate. The wall of the seminal cyst lesion confirmed infiltrating clear cell adenocarcinoma and non-invasive adenocarcinoma in the prostate segment of the central gland in the light of the ejaculatory conduct with "in situ" growth. Thus, the surgical specimen allowed radical exeresis with negative margins, guaranteeing minimally invasive surgery with preservation of continence and erection. CONCLUSION: We describe a new integral approach for the radical surgery of localized primary adenocarcinoma of the seminal vesicle. Despite its exceptional nature, the case allowed for a double reflection: a) The study of diffusion with MRI may suggest the diagnosis of malignity in this type of lesions; and b) Radical surgical treatment must include exeresis of the central portion of the prostate gland.

[Laparoscopic partial nephrectomy]. / Nefrectomía parcial laparoscópica.

OBJECTIVES: To analyze the surgical and oncologic outcome of prospective experience with laparoscopic partial nephrectomy. We describe the surgical technique and mid term oncological results achieved. MATERIAL AND METHODS: 60 patients were operated with this technique between June 2005 and June 2009. The mean age of patients was 58.9 [38-77] years, being 40 (66.7%) males and 20 (33.3%) women. The average BMI was 26.8 [18-40]. Laterality was 28 (46.7%) tumors rights and 32 (53.3%) left, being located in the upper pole in 14 (23.3%) patients, in the middle third in 13 (21.7%) in the lower pole in 22 (36.7%) and hiliar region in 11 (18.3%). In 23 cases (38.3%) tumors were located in the anterior valve, in 24 (40%) in posterior valve, in 10 (16.7%) at the outer edge and 3 (5%) at the inner edge. The average size tumor on CT was 3.3 [1-6.4] cm and in the surgical specimen 3.1 [1.2-7] cm. RESULTS: The mean operative time was 107.17 [50-185] min, with a warm ischemia time of 33 [0-70] min. In 56 cases (93.3%) had a single artery and 4 (6.7%) cases had 2 arteries. The artery was clamped alone in 15 patients (25%), artery and vein in 44 (73.3%) and no clamping was performed in 1 (1.7%). We repaired the urinary tract in 32 patients (53.3%), leaving ureteral catheter in all patients. 20% of patients (12) required transfusion. Intraoperative complications occurred in 5 patients (8.7%). These were: 1 splenic injury requiring splenectomy (1.7%), 1 tear in the vena cava, sutured laparoscopically (1.7%) and 3 cases of bleeding due to bulldog malfunction (5%). Postoperative complications occurred in 11 patients (18.7%) and these were: 1 wall hematoma that required reoperation (1.7%), 1 urinary fistula ending in renal atrophy and subsequent nephrectomy (1.7%), 3 intracavitary hematomas hich resolved conservatively (5%), 1 arteriovenous fistula that needed embolization (1.7%), 1 urinoma that was resolved with percutaneous drainage (1.7%) and 3 cases of postoperative fever (5%). Margins were positive in 1 patient (1.7%). In 49 cases (81.7%) histology was renal cell carcinoma, in 8 (13.3%) oncocytoma, in 2 (3.3%) angiomyolipoma and 1 (1.7%) metastasis. The average stay was 5 [3-29] days. Median follow up was 31 [12-61] months. There was a local recurrence at 16 months (hiliar primary tumor 2.5 cm) and an ipsilateral adrenal metastasis at 34 months (primary tumor 5.6 cm in left lower pole). CONCLUSIONS: In this series of laparoscopic partial nephrectomy low rate of complications, good oncologic results and low recurrence rate in the short term are shown. More patients and further monitoring is required to strengthen the functional and oncological outcomes of this surgical technique.

[Treatment of distal ureteral stricture by laparoscopic ureterovesical reimplantation]. / Tratamiento de la estenosis de uréter distal mediante reimplantación urétero-vesical laparoscópica.

INTRODUCTION: to analyse the results achieved to treat iliac or pelvic ureteric stricture using laparoscopic reimplantation of the ureter in a psoic bladder. MATERIAL AND METHOD: in a four-year period, we performed laparoscopic ureteral reimplantation in a psoic bladder in 6 patients (right/left 1:1; male/female 1:2; mean age 59.2 years, range 47-87). In 4 cases the lesion was iatrogenic and in 2 cases idiopathic. Ureteral resection with bladder cuff and cystorraphy followed by ipsilateral lymph node dissection was performed in idiopathic cases or those with history of previous urothelial tumour (4 cases in total) before ureteral reimplantation. Bladder was extensively mobilized and fixed to minor psoas tendon before performing ureteroneocystostomy. Mixed intra and extravesical technique with submucosal tunnel (Politano) was used in a case and in the remaining 5 cases extravesical technique with submucosal tunnel (Goodwin) was used. Mean follow-up was 26 months (range 18-34). RESULTS: there was no need to convert to open surgery. Time of surgery was 230 minutes in the case treated with Politano ureteroneocystostomy and 120 (range 75-150) in those treated purely extravesically. The mean hospital stay was 3.2 days (range 2-5). There were no intra or postoperative complications. Histologic assessment always revealed ureteral fibrosis and in 2 cases accompanying granulomatous inflammation and dysplasia. No patient suffered re-stricture or impairment in renal function during follow-up. CONCLUSIONS: laparoscopic ureteral reimplantation is an effective and safe minimally invasive technique to treat benign distal stricture of the ureter. Simplicity of extravesical reimplantation has an advantage over its intravesical counterpart.

[Laparoscopic extraperitoneal adenomectomy: surgical technique and preliminary results]. / Adenomectomía extraperitoneal laparoscópica: descripción técnica quirúrgica y resultados preliminares.

OBJECTIVE: We analyze the laparascopic adenomectomy preliminary results and describe the surgical technique, for benign prostatic hyperplasia (BPH), for glands greater than 60cc. MATERIALS AND METHODS: From January to April 2009 we have performed 10 laparoscopic adenomectomies. We performed a descriptive and retrospective study and early postoperative results were analyzed. Descriptive statistical analyses were performed using IPSS 17.0. The surgical technique is described step by step. RESULTS: Conversion to open surgery was not required, and none of the patients had serious peri-operative and post-operative complications. None of the ten patients required blood transfusions. Median operating time was 112,5min (80-135). Median hospital stay was 3,5 days (2-5) and median catheterization period was 7 days (3-21). The median prostate enucleated weight was 62gr. (40-93). The median postoperative Qmax was 18,8ml/seg and the median score of IPSS was 5. CONCLUSIONS: Laparoscopic adenomectomy is a low rate morbidity technique and reproducible in centers with laparoscopic skills. Prospective and comparative studies with open surgery will be necessary to choose the best technique for our patients.

[Recurrent nonparasitic chyluria]. / Quiluria redicivante no parasitaria.

OBJECTIVE: To describe a case of recurrent chyluria and review the diagnostic and therapeutic methods. METHODS/RESULTS: A case of non parasitic recurrent chyluria is presented. Retrograde pyelography demonstrated pyelolymphatic reflux. The patient presented chemical pyelitis secondary to the contrast medium which caused remission of the condition. CONCLUSIONS: Chyluria is uncommon in our setting. Postprandial cystoscopy permits identification of the compromised renoureteral unit and perform pyelic instillation of sclerosing agents. Surgery should be reserved for those cases in whom conservative management has failed.

[Scrotal invasive angiomyofibroblastoma. First reported case]. / Angiomiofibroblastoma invasivo escrotal. Primer caso descrito.

OBJECTIVE: To report a case of locally invasive angiomyofibroblastoma of the scrotum. To our knowledge, this is the first case of invasive scrotal angiomyofibroblastoma reported in the literature. METHODS: A case of invasive angiomyofibroblastoma of the scrotum is presented. The literature is reviewed with special reference to the etiopathogenesis, clinical features, diagnosis and treatment of this rare soft tissue tumor. RESULTS/CONCLUSIONS: The case described herein shows that angiomyofibroblastoma can be invasive.

[Granulomatous prostatitis. Analysis of 15 cases and review of the literature]. / Prostatitis granulomatosa. Análisis de 15 casos y revisión de la literatura.

OBJECTIVES: The present study describes our experience with granulomatous prostatitis, an uncommon disease entity, with special reference to the etiological factors and the clinical and pathological features. METHODS: 15 cases of granulomatous prostatitis seen at our department over a 2-year period were retrospectively analyzed. RESULTS: The most frequent etiological factor was surgery (TUR) or prostatic needle biopsy (53%). Prostate cancer was suspected in 8 patients based on the findings of DRE. CONCLUSIONS: The diagnosis of granulomatous prostatitis is based on the histological findings. Despite its low incidence, it is currently diagnosed more frequently due to the increase in TURP and prostatic biopsy procedures and the widespread use of intravesical BCG therapy for some superficial bladder tumors.

[Bladder leiomyoma during pregnancy]. / Leiomioma vesical durante el embarazo.

OBJECTIVE: To describe an additional case of rapidly growing leiomyoma of the bladder in a pregnant woman. METHODS: A case of leiomyoma of the bladder in a woman at 8 months of pregnancy is presented. Transurethral resection was performed, but the tumor recurred a few weeks later. The tumor was resected by partial cystectomy after delivery. CONCLUSIONS: Leiomyoma of the bladder is an uncommon benign lesion that is successfully managed by surgical resection. The rapid recurrence of the tumor in our patient can be ascribed to the hormonal changes during pregnancy.

[Treatment of erectile dysfunction with vacuum devices]. / Tratamiento de la disfunción eréctil con dispositivos de vacío.

OBJECTIVE: To analyze the results achieved with vacuum devices in the treatment of erectile dysfunction. METHODS: A telephone survey was conducted on 150 patients undergoing treatment with a vacuum device. Of these, 89 responded; 79 of which were considered valid for the study. The duration and frequency of use, side effects and degree of patient and partner satisfaction were analyzed. Mean follow-up was 59.5 months. RESULTS: There were 14 dropouts early in the course of treatment. The remaining 65 patients used the device for a mean duration of 34.6 months, 3.7 times monthly. 63.3% of the patients achieved erection in more than half of the attempts. The most frequent side effects were pain (27 patients) and ecchymosis (7 patients). Forty-eight patients discontinued treatment at 10.8 months' mean follow-up. The most common causes for discontinuing treatment were lack of efficacy, refusal of the partner and pain. CONCLUSIONS: Treatment of erectile dysfunction with the vacuum constriction device should be utilized as an alternative to intracavernosal drug-induced erection therapy when oral therapy fails or is contraindicated. A male with a stable partner and impotence arising from venous leakage or mild cavernous artery insufficiency is the ideal candidate.
