[Emergency conservative surgery on a unique kidney with broken multiple angiomyolipoma]. / Cirugía conservadora de urgencia en monorrena por rotura de angiomiolipoma múltiple.

A case of retroperitoneal hemorrhage due to the rupture of a multiple angiomyolipoma in a female with a unique kidney is described. Hipovolemic shock was the first symptom, being possible to perform on her a successful conservative surgery. Etiology, diagnostic methods and treatment of the spontaneous retroperitoneal hemorrhage are discussed.

[Comparative study between cystoscopy, urinary cytology, NMP-22 and a new method, bladder chek, in the follow-up of superficial bladder cell carcinoma]. / Estudio comparativo entre cistoscopia, citología urinaria, NMP-22 y un nuevo método, bladder chek, en el seguimiento del cáncer vesical superficial.

OBJECTIVE: The goal of this work tries to evaluate the utility of the qualitative determination of NMP-22 in the evaluation of the superficial bladder carcinoma in asymptomatic patients, comparing it with its quantitative determination, the cytology and the cystoscopy. MATERIALS AND METHODS: A simple of urine just voided was taken in 88 asymptomatic patient follow-up for superficial bladder cell carcinoma. This dose was distributed in 3 parts, for performed cytology, for determination of NMP-22, and 4 drops of the third part are added to device bladder chek. Later, we performed cystoscopy and transurethral resection in patients with a suspicion of bladder cancer. RESULTS: 26 patients had tumor relapse and 62 patients were free of disease. The sensitivity for the bladder chek was of 28%, 34.62% for NMP-22, 34.62% for cytology and 100% for cystoscopy. The specificity was of 93.55%, 80.33%, 87.10% and 87.10% respectively. The sensitivity by degree was 25 in G1, 28.57 in G2 and 50 in G3 for Bladder chek; 29.41, 42.86 and 50 for NMP-22; 23.53, 71.43 and 0 for cytology. The sensitivity by stages was 27.7 in Ta-1 and 50 in T2 for Bladder chek; 34.78 and 50 for NMP-22; 39.13 and 0 for the cytology. CONCLUSIONS: The low sensitivity of bladder chek invalidates it like alternative method to the cystoscopy in the follow-up of the superficial asymptomatic bladder cell carcinoma.

[Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis]. / Quiste epidermoide testicular: una rara entidad de dificil diagnostico preoperatorio.

Intratesticular epidermoid cysts are rare tumours that constitute one percent of all testicular masses. They are bening lesions that make differential diagnosis from malignant testicular tumours difficult. The absence of serum markers elevation and ultrasound imaging could support these lesions being bening epidermoid cysts, and in that case, conservative surgery is adequate. We present the case of a 22 years old patient who complains of a left testicular mass. In this case ultrasound diagnosis was non-specific and a left radical inguinal orchiectomy was performed.

[Surgical aspects in the third and fourth kidney retransplant]. / Aspectos quirúrgicos en los terceros y cuartos retrasplantes renales.

INTRODUCTION AND OBJECTIVES: A quarter of patients waiting for kidney transplantation are patients with previous graft failure. Outcome of first and second renal transplant make these the gold standard for end renal stage disease, but this is not so clear in the case of third and further renal transplant, especially at the time of organ shortage. We revise our experience in patients with three or more kidney transplants focusing on surgical aspects and graft outcome. MATERIAL AND METHOD: 1364 renal transplants have been carried out in our centre since 1975 until December 2003. We have retrospectively revised the 34 patients with three renal transplants and the 5 with four. We analyse the surgical technique, surgical complications and graft outcome. RESULTS: Mean age was 42 years (21-65). Average mismatches between donor and recipient was 3.2. All kidneys, but one case of living donor, were harvested from cadaver donors, mostly in multiple organ-procurement. Average time from the last renal transplant was 5 years (3 days-17 years) and from the last transplant carried out in the iliac fossa reused until the new transplant was 9 years (3 days- 17.5 years). All implants were performed through an iterative lumboliliac incision (25 on the right side, 11 on the left one and in 3 cases where side was not registered). Mean average duration of the procedure was 166 minutes (100-300). Nephrectomy of previous graft at the moment of the implant was carried out in 13 patients (33%). Vascular anastomosis was made on the common iliac vessels (50%) or on the external ones (50%) in end to side way, Ureteroneocystostomy was performed in an extravesical way except in 1 patient with cutaneous diversion. Vascular complications were 4 haemorrages (1 patient died), 3 venous and 2 arterial thrombosis. We had an abscess secondary to intestinal fistulae. Other surgical complications were 4 lymphoceles, three of them needed surgical treatment, and one perirenal haematoma treated in a conservative way. No urological complications were seen. In total 6 grafts (15%) were lost due to surgical complications. Graft actuarial survival rate at 1 year was 65%, 40% at 5 and 28% at 10 years. CONCLUSIONS: Three and four renal transplant survival rates are shorter than first and second ones. Iterative access through lumboiliac incision is associated with a higher vascular complication rate, probably in these patients a transperitoneal access would be better. Multicentric studies with higher numbers of patients are needed to define more clearly which patients would benefit from multiple kidney retransplants.

Trans-umbilical single-port radical nephrectomy with concomitant cholecystectomy.

OBJECTIVES: Occasionally, the development of laparoscopic procedures allows the performance of combined surgeries. Currently, some of these can be carried out by trans-umbilical single-port laparoscopy. MATERIAL AND METHODS: We report a patient with renal tumor of 4.5cm and cholelithiasis who undergone to trans-umbilical single port-right radical nephrectomy with concomitant cholecystectomy. This is the first case reported in Spain that this combined procedure is performed using umbilical single port surgery. RESULTS: No complications (intra or postoperative) have been described in this case, achieving proper control of tumor pathology and an excellent cosmetic outcome. CONCLUSION: In those cases in which multidisciplinary approach is required, surgery can be performed by trans-umbilical single-port laparoscopy as consequence of its reduced postoperative morbidity and better cosmetic results.

[Usefulness of abdominal leak point pressure determination in the diagnosis of female urinary incontinence in the TVT era]. / Utilidad de la determinación de la presión abdominal de fuga en el diagnóstico de la incontinencia de orina femenina en la epoca del TVT.

OBJECTIVE: To analyse our results about continence in the treatment of female urinary incontinence with the tension-free vaginal tape (TVT) procedure based on abdominal leak point pressure(ALPP). PATIENTS AND METHODS: Retrospective study of the fifty two patients who had urodynamic study and abdominal leak point pressure determination and were operated on between 1999 and 2002 for stress urinary incontinence. We reviewed the data of clinical history, physical examination and urodynamic report, surgery, complications, and objective and subjective results. Those patients having ALPP > 100 are included in group 1, between 61 and 100 in group 2 and less than 60 in group 3. RESULTS: There were 19 patients in group 1, 17 in group 2 and 16 in group 3. We found no difference between the three groups regarding age, delivery, menopause, hysterectomy, evolution, previous surgery, grade of cystocele, association of anterior colporraphy to TVT and type of anaesthesia. The Obrink clinical grade increased as the ALPP decreased (grade 3 in 26.32% of group 1, 31.58% in group 2 and 68.71% in group 3). 100% of patients in groups 1 and 2 were continent with effort and 93.75% in group 3. Complications, especially de novo instability or urgency-frequency episodes or persistence of instability in patients having mixed incontinence, caused a decrease in the satisfaction degree to 79% in group 1, 76.5% in 2 and 62.5% in 3. CONCLUSIONS: Abdominal leak point pressure determination does not change our decision of perform a TVT procedure but permits us to differentiate one group in which results could be worse.

[Upper urinary tract tumours]. / Tumores de urotelio superior.

OBJECTIVE: To evaluate diagnostic techniques, treatment and follow-up in 94 patients affected of upper urinary tract tumor. PATIENTS AND METHOD: From 1978 to december 2002 we operated 105 patients due to upper urinary tract tumor, although only 94 are valid for analysis. Mean age was 65 years and 85% were man. Haematuria was the most frequent symptom. RESULTS: Urography (93%), ecography (77%) and CT (67%) were the most used diagnostic techniques. Pelvic tumor was the most frequent (71%) and total nephroureterectomy including bladder cuff the chosen treatment (76.4%). Previous or simultaneous bladder tumor was observed in 23% cases and delayed in 30%. With a mean follow-up of 76 months the patient survival is 53%. CONCLUSIONS: Due to the high frequence of previous, simultaneous or delayed bladder tumors, the upper urinary tract tumor should be considered as a panurothelial disease, worsening the outcome of this kind of tumors.

[Corrective surgery of penile inward curvature]. / Cirugía correctora de la incurvación peneana.

OBJECTIVE: To evaluate the corporoplasty techniques performed on 59 patients to correct congenital penile curvature and Peyronie's disease. PATIENTS AND METHOD: From april 1991 to december 2001, 39 Nesbit technique, 12 Ruiz-Castañé method and 8 Essed-Schröeder procedure were performed on forty-four congenital curvatures and fifteen Peyronie's diseases. The mean age was 24 years old. Trying to hide the knots, in all patients except five a nonabsorbable inverting sutures were placed. RESULTS: The mean follow-up was 12 months. Postoperatively, 53 patients (86%) had satisfactory cosmetic and functional results. Four patients of five with absorbable sutures had residual curvature which needed another successful surgical correction. One patient complained of penile shortening, one of glans hypoaesthesia, one of foreskin oedema and five of palpable plication sutures. No differences were found depending on the applied surgical technique. CONCLUSIONS: The results reported are in accordance with the literature showing a higher recurrence rate with the absorbable sutures. The outcome is very similar with the three described techniques.

[Prevalence of orthostatic hypotension in elderly hypertensive patients in primary care]. / Prevalencia de hipotensión ortostática en ancianos hipertensos tratados en atención primaria.

OBJECTIVE: To find the prevalence of orthostatic hypotension (OH) and associated factors in elderly hypertensive patients in a primary care setting. DESIGN: Descriptive cross-sectional study. SETTING: La Marina Health Centre (an urban centre in Santander). PATIENTS: A random sample of 295 patients aged 65 years or older regularly assisted from hypertension. MEASUREMENTS AND MAIN RESULTS: Measurements of sitting and standing blood pressure were obtained. Orthostatic hypotension was defined as 20 mmHg or greater decrease in systolic or 10 mmHg or greater decrease in diastolic blood pressure after 1-minute or 5-minute standing. Associated diseases, symptoms upon standing, medication use, habits and other clinical assessments were also recorded. The prevalence of OH was 14.6%. The prevalence of systolic OH after 1-minute (OH-S1) and after 5-minute (OH-S5) standing was 5.8% in both, and the diastolic OH was 5.1% after 1-minute (OH-D1) and 4.1% after 5-minute (OH-D5) standing. By logistic regression analysis, association between higher level of systolic blood pressure and global OH was found, also with the presence of orthostatic intolerance symptoms (although only 25.6% of the patients with OH showed symptoms) and smoking. Beta-blockers and calcium channel blockers (different from dihydropyridines) use was associated with OH after 1-minute standing and smoking with OH after 5-minute standing. CONCLUSIONS: The detected prevalence is high and justifies the case finding of OH in elderly hypertensive patients in primary care. The symptoms of orthostatic intolerance are correlated with OH, but only 1 out of 4 patients showed symptoms. Smoking could be related with OH, so beta-blockers and calcium channel blockers (different from dihydropyridines) use.
