Conservative management of high-grade renal trauma.

INTRODUCTION: Renal trauma is the most common of urological trauma and accounts for up to 5% of all. The AAST scale is the most widely used to assess renal trauma. This study focuses on high-grade trauma, whose treatment has evolved towards a conservative approach, with techniques such as angioembolization. The aim is to describe the evolution in the management of high-grade renal trauma in all patients treated at La Paz University Hospital from 2001 to 2022. METHODS: A descriptive retrospective study was conducted on patients treated at the hospital. The study was divided into two periods (2001-2010 and 2011-2022). A total of 285 patients with renal trauma were collected, of which 54 were high grade. The main variable is the type of management, conservative (embolization) or interventional through nephrectomy. RESULTS: In the completed series, there was a decrease in radical nephrectomy in high-grade renal trauma from 50% to 13.8% over time, with an increase in embolization from 23,1% to 44,8%. In patients with isolated renal trauma, those treated with embolization increased from 28.6% to 69.2%, while those undergoing radical/partial nephrectomy decreased from 42.8% to 7.69%. CONCLUSION: The management of renal trauma has evolved over the years in our center. The number of patients treated by embolization has increased, while the number of complications and nephrectomies has decreased.

Randomized clinical trial on the use of IMAGE1 S LIGHT (SPIES) vs. white light in the prevention of recurrence during transurethral resection of bladder tumors: Analysis after 12-month follow-up.

INTRODUCTION: The improved image resolution of IMAGE1 S technology will increase tumor detection, achieve a greater number of complete resections, and would probably have an impact on the reduction of recurrences. AIM: The primary objective was to compare the recurrence rates of IMAGE1 S vs. white light during transurethral resection of the bladder (TUR); the secondary objective was to compare the complication rates according to Clavien-Dindo (CD) at 12 months of follow-up. METHODS: Prospective, randomized 1:1, blinded clinical trial. Recurrence and complication rates according to CD were analyzed using chi-square/U Mann-Whitney tests and recurrence-free survival (RFS) using Kaplan-Meier curves. The European Association of Urology (EAU) 2021 scoring model was used. RESULTS: The analysis included 103 participants; 49 were assigned to the IMAGE1 S group and 54 to the white light group. Recurrence rates were 12.2% and 25.9%, respectively (P = .080). The low and intermediate risk group had a lower recurrence rate with IMAGE1 S (7.7% vs. 30.8%, P = .003) and a higher RFS with IMAGE1 S (85.2% vs. 62.8% Log Rank: 0.021), with a Hazard Ratio of 0.215 (95% CI: 0.046-0.925). No differences were observed in the high and very high-risk groups. Complications were mostly grade I and rates were similar between both groups (IMAGE1 S 20.4% vs. white light 7.4% P = .083). CONCLUSIONS: There were no differences in the recurrence rates between groups. However, the low and intermediate risk group had a lower recurrence rate with IMAGE1 S. In addition, perioperative complication rates were not higher.

Zinner Syndrome with Ectopic Ureter Emptying into Seminal Vesicle.

A 66-year-old male patient in follow-up in the urology department for a non-muscle-invasive bladder cancer was detected by ultrasound to have absence of the left kidney and a cystic, multilobed image at the location of the seminal vesicle. Magnetic resonance imaging reveals left renal agenesis and the existence of multiple cysts in the ipsilateral seminal vesicle that reaches a size of 6.9 × 3.7 cm, as well as a ureteral remnant that opens into the seminal vesicle. The patient does not present urinary symptoms, neither pain with ejaculation nor hematuria. A triad of seminal vesicle cyst, ipsilateral renal agenesis, and ipsilateral ejaculatory duct obstruction is known as Zinner syndrome. Congenital anomalies of the seminal vesicles are rare; some of them are associated with malformations of the upper urinary system. Seminal vesicle cysts are associated with ipsilateral renal agenesis and ectopic or dysplastic ureter. Patients may remain asymptomatic and be diagnosed incidentally or may present with symptoms such as increased urinary frequency, dysuria, recurrent infections, pain with ejaculation, and perineal discomfort.

Prognostic value of urinary cytology for detecting urothelial carcinoma recurrence after radical cystectomy.

INTRODUCTION: Urethral or upper urinary tract (UUT) recurrence of urothelial carcinoma (UC) after radical cystectomy (RC) are rare (4-6%), and their diagnosis usually occurs within the first two years. Although it is known that its early detection offers benefit in terms of survival, currently there are no clear recommendations for the detection of recurrence in the remnant urothelium (RU). Our aim is to determine the diagnostic value of urinary cytology for the detection of recurrences in the RU and to estimate its impact as an early diagnostic method on survival. MATERIAL AND METHODS: Retrospective review of patients who underwent RC for urothelial carcinoma between 2008-2016, with a follow-up of at least 24 months. RESULTS: The study included 142 patients. In a median follow-up of 68.5 months, nine patients (6.3%) presented recurrences in the RU (urethra: four, UUT: four, synchronous: one). The sensitivity and specificity of urinary cytology for the diagnosis of UUT recurrences were 20% and 96%, respectively. No significant differences were found between overall survival and cancer-specific survival among patients according to the urinary cytology results. CONCLUSION: Recurrences in the RU after RC are infrequent; our study has shown that urinary cytology offers a low sensitivity for their diagnoses. For these reasons, we do not consider that urinary cytology provides useful information for surveillance of these patients.

Magnetic resonance as imaging diagnostic tool in prostate cancer: New evidences-The EAU Section of Uro-Technology position. / La resonancia magnética como herramienta para el diagnóstico del cáncer de próstata: nuevas evidencias y posicionamiento de la ESUT (EAU Section of Uro-Technology).

Prostate cancer (PCa) is the second leading cause of cancer-related mortality and the most frequently diagnosed male malignant disease among men. The manifestation of PCa ranges from indolent to highly aggressive disease and due to this high variation in PCa progression, the diagnosis and subsequent treatment planning can be challenging. The current diagnostic approach with PSA testing and digital rectal examination followed by transrectal ultrasound biopsies lack in both sensitivity and specificity in PCa detection and offers limited information about the aggressiveness and stage of the cancer. Scientific work supports the rapidly growing use of multiparametric magnetic resonance imaging as the most sensitive and specific imaging tool for detection, lesion characterization and staging of PCa. Therefore, we carried out an updated review of magnetic resonance imaging in the diagnostic PCa reviewing the latest papers published in PubMed.

[Experimental laparoscopic renal autograft as learning laparoscopic model]. / Autotrasplante renal laparoscópico experimental como modelo de aprendizaje de técnica laparoscópica.

INTRODUCTION: Laparoscopic surgery requires a long training period of time in which the complexity of the training is increased. GOALS: The technique presented in this paper has been developed in order to find an experimental model that allows us to improve the learning of the vascular suture. Our main goal was to evaluate this technique as an experimental model for the vacular anastomosis, not to obtain a functional autotransplant. In this regard, here we summarize our experience during the first two cases performed. MATERIAL AND METHODS: Laparoscopic renal autotransplant was perfomed in female lab pigs weighing 15-20 kg. International Experimental Animal Care rules were accomplished. RESULTS: After sacrifizing the animals, only one case of vascular thrombosis was observed. The other cases showed normal arterial and venous flow. CONCLUSIONS: Experimental Renal Laparoscopic autotransplant constitutes a good surgical model. We are trying to implement the technique in the clinics in the next future.

[Laparoscopic adrenalectomy. Five-year experience]. / Suprarrenalectomía laparoscópica. Experiencia de 5 años.

OBJECTIVE: Adrenal conditions requiring surgery are uncommon and are usually seen in several surgical departments. Our experience in laparoscopic management of adrenal pathology after almost five years of use of laparoscopy for retroperitoneal conditions at our center is reported. MATERIALS AND METHODS: A total of 37 laparoscopic adrenalectomies were performed over 53 months for benign and malignant conditions. The transperitoneal approach was used in most cases (97%) because of the greater surgeon experience with this route. Pregnancy and suspected periadrenal infiltration were considered as absolute contraindications. RESULTS: Mean operating time was 90 minutes, mean intraoperative bleeding 80 ml, and mean hospital stay was 2 days. The main complication was one death. A malignancy was found in 4 patients (10%), while all other patients (90%) had a benign condition, including 8 pheochromocytomas. CONCLUSIONS: Laparoscopy is considered to be the gold standard for benign adrenal conditions. When the malignant mass is a single metastasis from a primary tumor, the laparoscopic approach appears to be reliable. When the malignant lesion is a primary adrenal tumor, laparoscopic management is more controversial, although the results reported by experienced surgeons in their series appear to be adequate.

[Laparoscopic nephron-sparing surgery. 5 years' experience]. / Cirugía conservadora de parénquima renal laparoscópica. Cinco años de experiencia.

INTRODUCTION: Laparoscopic nephron-sparing surgery is among the most complex urological procedures currently performed. Open surgery continues to be the gold standard of care, but the laparoscopic approach is gaining ground slowly but surely. Our 5 years' experience is reported. MATERIALS AND METHODS: From September 2004 to March 2009, 38 laparoscopic nephron-sparing procedures were performed at our hospital. A transperitoneal laparoscopic approach was used in all cases, with en bloc clamping of renal hilum in most patients. RESULTS: Mean operating time was 141 min, mean intraoperative bleeding 130 mL, mean warm ischemia time 24 min, and mean hospital stay 3.3 days. Bleeding was the most common complication (requiring transfusion in 13.5% of patients). Positive surgical margins were found in 5.4% of patients. CONCLUSIONS: Adequate selection of the patient (tumor size, location) and the procedure to be used, surgeon experience, and surgical skills are essential for achieving good oncological results and for minimizing the complications of this demanding procedure.

A review of penile cancer.

UNLABELLED: Cancer of the penis is a rare tumour in Europe and mainly affects the elderly patient population. The aim of this paper was to analyse and study the characteristics of this tumour, in our patient population. MATERIALS AND METHODS: A retrospective study was conducted on penile tumours diagnosed and treated in the Urology Department of the Hospital Universitario La Paz, Madrid, in the last ten years. RESULTS: A total of 34 patients were diagnosed and treated. The mean age at presentation was 71.27 years. The mean time between symptoms and the first consultation was 12.54 months with a median of 6 months. The most common form of presentation was balanoposthitis (32%) and the most common site in our series was the glans. Partial penectomy was performed in 22 cases, total amputation in 8, and local excision in 3. DISCUSSION: Carcinoma of the penis is a pathology which mostly affects elderly patients; in our series, the highest incidence was observed in patients in the group aged 75-84 years. The most common histological type was epidermoid carcinoma in its various forms of presentation. We recorded a mortality of 23%. CONCLUSION: Penile carcinoma is a rare pathology which affects elderly persons and is diagnosed late.

[Clinical pathway for TUR of bladder neoplasms. Analysis of the first 2 years of its implementation]. / Vía clínica para la RTU de neoformaciones vesicales. Análisis de los 2 primeros años de implantación.

OBJECTIVE: To analyze the results of the first two years of application of the clinical pathway for transurethral resection (TUR) of bladder tumors at La Paz University Hospital. METHODS: We developed a clinical pathway of 4 hospital stays (5 days) for TUR of the bladder that included the following: matrix-verification, treatments prescribed, verification of changes, patient information sheet and patient satisfaction questionnaire. The information for the evaluation of the results were obtained from the pathway records and data on the activities of the Urology services. To assess the results for efficiency in the use of resources, the mean duration of hospital stay of patients in the pathway were compared with that of a control group comprised of 50 randomly selected patients submitted to TUR of the bladder in 1997. RESULTS: From June 1998 to May 2000, 481 of the 494 (97.4%) treated patients entered the clinical pathway. CONCLUSIONS: In our experience, the clinical pathway for the urinary bladder is a useful instrument for developing the clinical management of this condition. It reduces the unwanted changes in patient care and hospital stay, carries a low incidence of complications and readmissions, and achieves a high degree of patient satisfaction.
