European Association of Urology biochemical recurrence risk groups after radical prostatectomy: External validation and identification of independent risk factors for progression and death.

BACKGROUND: The EAU proposed a progression and death risk classification in patients with biochemical recurrence after radical prostatectomy (PR). OBJECTIVE: To validate the EAU BCR-risk classification in our setting and to find factors related to progression and death. MATERIAL AND METHODS: Multicenter, retrospective, observational study including 2140 patients underwent RP between 2011 and 2015. Patients with BCR were identified and stratified in low risk (PSA-DT >1yr and pGS <8) or high-risk (PSA-DT ≤1yr or pGS ≥8) grouping. PSA and metastatic free survival (PSA-PFS, MFS), cancer specific survival (CSS) and overall survival (OS) were calculated (Kaplan Meier curves and log-rank test). Independent risk factors were identified (Cox regression). RESULTS: 427 patients experienced BCR (32.3% low-risk and 67.7% high-risk). Median PSA-PFS was 135,0 mo (95% CI 129,63-140,94) and 115,0 mo (95% CI 104,02-125,98) (p<0,001), for low and high-risk groups, respectively. There were also significant differences in MFS and OS. The EAU BCR risk grouping was independent factor for PSA-progression (HR 2.55, p 0.009). Time from PR to BCR, was an independent factor for metastasis onset (HR 0.43, 95% CI 0.18-0.99; p 0.044) and death (HR 0.17, 95% CI 0.26.0.96; 23 p 0.048). Differences in MFS (p 0.001) and CSS (p 0.004) were found for <12, ≥12-<36 and ≥36 months from PR to BCR. Others independent factors were early salvage radiotherapy and PSA at BCR. CONCLUSIONS: High-risk group is a prognostic factor for biochemical progression, but it has a limited accuracy on MP and death in our setting. The inclusion of other factors could increase its predictive power.

The impact of psychiatric pathology on the prognosis and survival of men with prostate cancer undergoing radical prostatectomy.

INTRODUCTION AND OBJECTIVE: Cancer-specific anxiety is the most frequently reported psychological response after radical prostatectomy (RP). We evaluated the prevalence of pretreatment psychiatric pathology in patients with prostate cancer undergoing RP and identified the effects of psychiatric diagnoses on their survival and prognosis. MATERIAL AND METHODS: Retrospective multicenter observational study including 1078 men treated with RP for organ-confined prostate cancer. Groups: GP: patients with psychiatric pathology prior to RP; GNP: patients without psychiatric pathology prior to RP. Urological, oncological and psychiatric variables, descriptive statistics and multivariate analysis were included. RESULTS: 37.94% of patients presented a psychiatric diagnosis. Adjuvant radiotherapy was required in 27.83% and hormone therapy in 23.38%; being more frequent in GP. Cancer-specific survival was higher in GNP. Anxiety, depression, insomnia, smoking, psychosis and alcoholism were the most frequent. Low TNM and low presence of LUTS and SUI increased the probability of absence of psychiatric pathology. Fatigue, erectile dysfunction and cognitive impairment after RP with RT and/or HT were higher in GP. Older age and higher PSA at diagnosis increased the relative risk of psychiatric pathology and worse outcome. The most frequently related factors were RP, PSA, age and survival time. CONCLUSIONS: Psychiatric pathology is present in patients undergoing radical prostatectomy for prostate cancer, with a high impact on survival and prognostic outcomes.

Single-port robot-assisted retroperitoneal surgery: A feasible approach.

INTRODUCTION: The concept of surgery through a single incision has been pursued in the field of minimal invasion for the treatment of different pathologies. This, added to a retroperitoneal approach, implies less aggression for the patient at different levels. We describe the first cases of single-port robot-assisted retroperitoneal surgery (SP-RARS) in our country using the da Vinci Xi® system. MATERIAL AND METHODS: We present two cases of patients with right adrenal masses larger than 4 cm. The first case was a 55-year-old woman with an incidental diagnosis of angiomyolipoma, and the second case was a 62-year-old man with a non-functioning adrenal adenoma. Both cases were operated through a single 4-cm subcostal incision using the da Vinci Xi® system, annulling arm 4 without reallocating laterality on the surgeon's console. RESULTS: Both surgeries were performed with console times of 75 and 150 min, respectively, with access and docking times below 30 min. Bleeding was less than 100 cc in both surgeries without the need to make accessory incisions or leave a drainage tube. The surgical specimens were removed through the same initial incision without the need for enlargement. Postoperative intravenous analgesia was not necessary in any case (VAS 0) and hospital stay was less than 24 h in both patients without reporting any complications. CONCLUSIONS: SP-RARS is a feasible approach using the da Vinci Xi® system.

Non-metastatic castration-resistant prostate cancer: management recommendations.

INTRODUCTION AND OBJECTIVE: Survival and quality of life (QoL) of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) deteriorate significantly when they develop metastases. New generation antiandrogens (apalutamide, enzalutamide and darolutamide) can prolong metastasis-free survival (MFS) and overall survival (OS) in these patients, maintaining their QoL. MATERIAL AND METHODS: After the performance of a systematic review of the literature, a scientific committee reached a consensus on simple and practical recommendations to consolidate and improve the management of patients with nmCRPC in urology consultations. RESULTS: Recommendations are made on the frequency of PSA determination and imaging tests in patients with nmCRPC. The importance of co-morbidities in patients with nmCRPC is also highlighted, and recommendations are also made on functional and QoL assessment that can be carried out during urology consultations. The efficacy, safety, and effects on QoL of new generation antiandrogens are reviewed. CONCLUSIONS: To evaluate treatment of patients with nmCRPC, it is necessary to consider co-morbidities and QoL, in addition to age. New generation antiandrogens are a safe and effective treatment option for patients with nmCRPC. The recommendations of this review can be helpful in optimizing the management of nmCRPC patients in urology consultations.

Single-port retroperitoneoscopic adrenalectomy: Initial experience and standardization of the technique.

INTRODUCTION AND OBJECTIVE: The minimally invasive surgical approach to adrenal gland pathology is the most widely used nowadays, and retroperitoneoscopy occupies a relevant place. However, the evolution of these techniques towards even less invasive surgery through single-port access is anecdotal. The aim of this work is to describe our initial experience in single-port retroperitoneoscopic surgery (SPORS) of the adrenal gland focusing on perioperative data and postoperative pain. MATERIAL AND METHODS: We collected and analyzed the demographic and operative data of a series of patients undergoing adrenalectomy through SPORS. All procedures were performed through a single 3-4 cm subcostal incision with a multichannel port. Surgical data such as operative time, bleeding, length of stay and presence of complications were collected. We used the visual analog scale (VAS) for postoperative pain assessment. RESULTS: From December 2018 to August 2020, 6 patients with different types of adrenal pathology underwent consecutive surgeries in our Department by the same surgeon using SPORS. All surgeries were performed without requiring accessory trocar placement or reconversion to open surgery. The mean operative time was 91.6 ±â€¯16.3 min, with <150 mL bleeding, mean length of stay of 35.8 ±â€¯13.3 h and postoperative pain of VAS ≤3 (median 0.5). The mean size of specimens was 57.8 ±â€¯18 mm. No complications were reported according to the Clavien-Dindo scale. CONCLUSIONS: Even in initially adverse cases, SPORS adrenalectomy is a feasible and safe technique with good cosmetic and perioperative results.

Safety and efficacy of various strains of bacille Calmette-Guérin in the treatment of bladder tumours in standard clinical practice. / Eficacia y seguridad de distintas cepas de BCG en el tratamiento del tumor vesical en práctica clínica habitual.

BACKGROUND: The natural progression of bladder tumours (nonmuscle-invasive bladder cancer [NMIBC]) is recurrence with a high rate of progression. Bacille Calmette-Guérin (BCG) has been shown effective in reducing these rates, but there are few comparative studies between strains. MATERIAL AND METHODS: An observational, prospective and multicentre registry studied 433 patients with a 12-month follow-up visit from 961 registered patients, assessing disease-free survival (DFS), progression-free survival (PFS) cancer-specific survival (CSS) and adverse effects. We studied the Tice, Russian, Tokyo, Connaught and RIVM strains. RESULTS: The sociodemographic data, NMIBC history, comorbidities, size, number, stage, grade, associated carcinoma in situ and transurethral resection were well balanced. DFS: There were 85 relapses (19.6%). The median DFS time was 20months. When comparing the various strains, we detected no statistically significant differences (log-rank test; P=.93). LPS: There were 33 cases of progression (7.62%). When comparing the various strains, we detected no statistically significant differences (log-rank test; P=.69). CSS: Seven patients died (1.68%). When comparing the various strains, we detected no statistically significant differences (log-rank test; P=.93). In terms of safety, 33.3% of the patients presented some type of adverse effect, mostly lower urinary symptoms (no urinary tract infections) <48h, >48h and haematuria. According to the Common Toxicity Criteria of the European Organisation for Research and Treatment of Cancer, 92.7% of the patients were grade1. There were no statistically significant differences between the strains. CONCLUSIONS: In this intermediate analysis, the risk of recurrence, progression, specific death and safety were independent of the BCG strain employed.

Bladder cancer in Spain 2011: population based study.

PURPOSE: We estimate the annual incidence of bladder cancer in Spain and describe the clinical profile of patients with bladder cancer enrolled in a population based study. MATERIALS AND METHODS: Using the structure of the Spanish National Health System as a basis, in 2011 the AEU (Spanish Association of Urology) conducted this study with a representative sample from 26 public hospitals and a reference population of 10,146,534 inhabitants, comprising 21.5% of the Spanish population. RESULTS: A total of 4,285 episodes of bladder cancer were diagnosed, of which 2,476 (57.8%) were new cases and 1,809 (42.2%) were cases of recurrence, representing an estimated 11,539 new diagnoses annually in Spain. The incidence of bladder cancer in Spain, age adjusted to the standard European population, was 20.08 cases per 100,000 inhabitants (95% CI 13.9, 26.3). Of patients diagnosed with a first episode of bladder cancer 84.3% were male, generally older than 59 years (81.7%) with a mean ± SD age of 70.5 ± 11.4 years. Of these patients 87.5% presented with some type of clinical symptom, with macroscopic hematuria (90.8%) being the most commonly detected. The majority of primary tumors were nonmuscle invasive (76.7%) but included a high proportion of high grade tumors (43.7%). According to the ISUP (International Society of Urologic Pathology)/WHO (2004) classification 51.1% was papillary high grade carcinoma. Carcinoma in situ was found in 2.2% of primary and 5.8% of recurrent cases. CONCLUSIONS: The incidence of bladder cancer in Spain, age adjusted to the standard European population, confirms that Spain has one of the highest incidences in Europe. Most primary nonmuscle invasive bladder cancer corresponded to high risk patients but with a low detected incidence of carcinoma in situ.

[Neprhon sparing surgery for renal tumours on kidney transplantation]. / Cirugía conservadora en el tratamiento de los tumores renales de novo en injertos de trasplante renal.

INTRODUCTION: Nowadays, nephron sparing surgery for renal carcinoma achieves good oncological results, similar to radical surgery, with the advantage of preserving renal function. Renal cell carcinomas appear de novo in 4.6% of post-transplant patients compared with 3% of tumors in the general population, affecting less than 10% to renal allograft. OBJECTIVE: The purpose is to analyze our experience and make a literature review about the role of nephron sparing surgery to treat de novo renal tumours in renal grafts. MATERIAL AND METHODS: A retrospective and descriptive analysis has been realized, finding four patients who presented with de novo renal tumours over renal graft after kidney transplantation and treated by nephron sparing surgery. A Medline review is done to search similar series published. Oncological and functional results were reviewed and analyzed. We worked with SPSS 12.0 software. RESULTS: Medium age at diagnosis was 46.5 y (42-62). Medium size was 2.4cm. (1.5-3.5) and final histology showed medium tumours size of 3.0cm. (1.7-3.5). Medium hospital stay was 6.0d. Medium time from transplantation to diagnosis was 92 months (42-192). NSS was done in all cases, in 3 cases tumorectomy and one partial nephrectomy. Transfusion was only needed in one case. All cases had pT1aN0M0 RCC histology exam. Renal function did not change from preoperative. All patients are free of progression with a medium follow-up of 46.5 months (15-58). CONCLUSIONS: NSS could be an option to treat graft tumours in selected cases, preserving renal function. In our experience, is a safe and efficient treatment in patients with small de novo renal tumours over renal graft.

[Kaposis sarcoma in a renal graft]. / Sarcoma de Kaposi sobre injerto renal.

Kaposi's sarcoma is an infrequent tumor of unknown cause, but with a higher impact in immune depressed individuals, particularly in HIV and transplant patients. It usually appears as a benign cutaneous lesions, while the invasive visceral form is uncommon with malignant evolution and wit rare remission. We present a patient with a Kaposi's sarcoma localised in a renal graft and bad response even when immuno suppression was discontinued.

[Clinicopathological study of incidental cancer prostate in patients undergoing surgery for symptomatic diagnosis of BPH]. / Estudio clínico-patológico sobre el cancer de próstata incidental en pacientes intervenidos bajo el supuesto diagnóstico de HBP sintomática.

UNLABELLED: OBJECTIVES-INTRODUCTION: Retrospective study of a series of patients with prostate surgery (suprapubic prostate adenomectomy -APS-, and prostate transurethral resection -RTU-P-) for presumed BPH symptomatic non-respondent to the conservative medical treatment. Analysis of prevalence, incidence, clinical-pathological, treatment, tumor progression and evolution of the patients with incidental prostate cancer (CPI) detected. MATERIAL AND METHODS: 1593 patients with prostate surgery (APS and RTU-P) during 6 years (1996-2001) were revised. APS 35%, RTU-P 65%. Revision of all pathological anatomy of surgical specimens and the evolutions of the patients with CPI. RESULTS: 78 CPI; Prevalence 4,89%; Incidence 13 cases/year. Mean age 73.6 years. Digital rectal examination was normal in 100%, mean PSA 6 ng/ml (0.5-30). Group APS: 25 CPI (32%); prevalence 4.55%; incidence 4 cases/year; mean PSA 7.7 ng/ml (2.8-30); mean weight resection 65 gs. Group RTU-P: 53 CPI (68%); prevalence 5,07%; incidence 9 cases/year; mean PSA 5.2 ng/ml (0,5-29); mean weight resection 20 gs. 22% biopsy previously by high PSA, mean PSA 14 ng/ml (4,8-30). Gleason average 5 (mean 4.8), rank 3-8. pTla 66%, pTlb 33%. TREATMENT: 57% follow-up watched without treatment (wait and see); 18% hormonal treatment; 3% finasteride; 9% Radical Prostatectomy; 9% radiotherapy. Follow Lost 4%. Mean follow-up 47.19 months (12-96). Tumor progression 13.3% (10 patients). Specific CPI mortality 2.6% (2 patients). CONCLUSIONS: We didn't observe significant differences between the prevalence of CPI in both groups (APS and RTU-P). The detected tumours were mainly well differentiated and in stage pTla. In more than half of the cases an expectant attitude without treatment was decided. 13,3% of tumor progression after 47.19 months of follow mean and specific CPI mortality 2.6%.

[Traumatic urethral disruption in women. A rare entity. Report of two cases]. / Rotura traumática de uretra femenina: una rara entidad. Aportación de dos casos.

We present two cases of urethral disruption in women, a very uncommon situation because of the anatomical features. Yet it must be always suspected in all women under a pelvic politraumatism, for eviting important problems. Both cases are traffic politraumatized young girls presenting with pelvic fracture, among others. The surgery performed was combined suprapubic-transvaginal approach, even in one a previous endoscopic realinement was done, who also needed endoscopic complementary treatment: electrofulguration of a fistulous bridge. Outcome of both is fine, achieving good continence. We also make a literature review.

[Double-barreled wet colostomy: analysis of a urinary diversion]. / Colostomía húmeda en doble barra: análisis de una derivación.

We analyse our experience in performing the wet colostomy, also called urocolostomy and present seven cases treated at our hospital in which this was used. We present: a) three women, one underwent an urocolostomy as a result of a myelomeningocele with urinary and fecal incontinence, another because of a pelvic malignancy, and the third after developing a post radiotherapy cysto-proctitis; b) four men, one underwent this surgical procedure as a result of a traumatic paraplegia with multiple urinary fistulae and neurogenic bladder, the other three were secondary to pelvic malignancies (two bladder and one sigmoid malignacies). The outcome was fine in all cases with no pyelonephritis or metabolic imbalances; in all cases it represented a good option for these patients.

[Surgical management of renal cell carcinoma with vena cava-right atrium thrombus]. / Cirugía del carcinoma renal con trombo tumoral en vena cava-aurícula.

Historically the presence of a thrombus in vena cava was associated with worse prognosis in patients with renal cell carcinoma, and the effective of surgery limited. However a extensive tumor thrombi can be present without evidence of lymph node and distant metastasis, an aggressive surgical approach with curative intent is justified. We retrospectively reviewed 25 patients with renal cell carcinoma and thrombus in vena cava and they underwent radical nephrectomy and thrombectomy. The IRM allowed to know the level of the thrombus into vena cava in all patients: 56% level I, 8% level II, 26% level III. There were 14 pT3b, 8 pT3c, 3 pT4, and 48% N+. The rate of complications was 36% and there were 4 perioperative death (16%). Patients without lymph node and no distant metastasis had a mean survival of 64% 46%, 37% to 2, 3, 4 years respectively. Patients with lymph node invasive an distant metastasis the prognosis was poor. We no noted correlation between level thrombus and prognosis.

[Conservative surgery for renal carcinoma]. / Cirugía conservadora en el carcinoma renal.

OBJECTIVES: To report on our experience in conservative surgery for renal cell carcinoma, pointing at indications, surgical techniques and results. We also make a review of the literature. MATERIAL AND METHODS: From 1975 until 1997, 231 patients underwent surgical treatment of renal cell carcinoma. In 17 cases conservative surgery was done. 11 patients were male and 6 female, with age range 33-78 years. Polar nephrectomy was done in 4 cases and tumorectomy in 13 cases. The indication was elective in 10 cases, and imperative in 7 due to: 4 bilateral carcinomas, 1 chronic renal failure, 1 von Hippel Lindau disease and 1 tumor associated with surgical lithiasis of the kidney. RESULTS: 58.8% of the patients did not have clinical symptoms and the diagnose was incidental. The average size of the tumors was 3.8 cm. The pathological stage was: 3 cases T1N0M0 and 12 T2N0M0. All the T1 cases had an incidental diagnose. The complications were: 1 urinary fistula, 1 haematoma, and 1 case of postoperative fever. All these complications were solved in a conservative way. We had tumoral recurrence in one patient affected with von Hippel Lindau disease. It appeared 4 years after the surgical procedure and required radical nephrectomy. One patient died 24 months after surgery because of causes not related with renal tumor. The rest of the patients are alive, with no tumoral recurrence, within an average follow-up of 49.6 months. None of the patients needed dialysis. CONCLUSIONS: Our experience, though not great is enough to demonstrate the benefits of conservative surgery for renal cell carcinoma. Partial nephrectomy in selected patients and with the appropriate surgical technique offers short-term results similar to those obtained with radical nephrectomy. It is indispensable to make the resection and intraoperative pathological study of a margin of renal parenchyma surrounding the tumor, and also to examine the whole surface of the kidney to search for satellite tumoral nodules. It is very important to do a close follow up of these patients after the surgery.

[A solitary cerebellar metastasis: a diagnostic exercise]. / Metástasis cerebelosa solitaria: un ejercicio diagnóstico.

Presentation of a solitary cerebellar mass lead us to think about the presence of a primary tumour or the possibility of a pulmonary, mammary or digestive metastasis. However, once discarded these origins, is necessary to search the primary neoplasms in less frequent organs. Approximately, 5% of all intracranial metastasis have it's origin in a renal cancer. These lesions generally appear at the supratentorial area and within a generalized disease. In the other hand, the presentation of a solitary cerebellar metastasis from a renal carcinoma without affectation of other organs is a very unusual fact. We present a case of these characteristics discussing about diagnostic, therapeutic and prognostic aspects of this unpredictable tumor.

[Marsupialization via minilaparotomy in the kidney transplant]. / Marsupialización mediante minilaparotomía en el trasplante renal.

OBJECTIVE: To describe the results of treatment of posttransplant lymphoceles by marsupialization through a mini-laparotomy. METHODS: From March 1996 to May 1998, 7 patients with a symptomatic lymphocele that had not been resolved by conservative treatment with drainage and povidone-iodine sclerosis underwent internal marsupialization to the peritoneal cavity through a minilaparotomy. RESULTS: All patients showed a good postoperative course and were discharged two days after the procedure. Recent US scans of 5 patients showed a renal graft with a normal appearance and no perineal collections. Two patients had a recurrence; one of them was symptomatic and required another treatment. Drainage and povidone-iodine sclerosis resolved this condition. CONCLUSIONS: Marsupialization through a mini-laparotomy is an alternative to the laparoscopic approach and does not require new instruments or learning a new technique.

[Renal carcinoma with tumor thrombus in the vena cava and auricle. Experience and review]. / Carcinoma renal con trombo tumoral en vena cava-aurícula. Experiencia y revisión.

OBJECTIVES: To report on our experience in the treatment of renal cell carcinoma with vena caval or right atrial extension, with special reference to the level of involvement and the surgical technique indicated for each case. METHODS: From early 1975 to April, 1997, 212 patients underwent surgery for renal cell carcinoma. Of these, 15 patients (11 male, 4 female), aged 27 to 73 years, had a tumor thrombus extending to the inferior vena cava. The tumor was located in the right kidney in 11 patients and in the left kidney in 4 patients. The tumor thrombus was infrahepatic in 10 cases, it extended beyond the suprahepatic veins in 3 cases, and 2 cases showed right atrial extension. The 10 patients with infrahepatic caval thrombus underwent radical nephrectomy with cavotomy and thrombus removal. In the remaining 5 patients with suprahepatic or atrial extension, thrombus removal was performed via cardiopulmonary by-pass with hypothermic circulatory arrest, with the assistance of a team of cardiac surgeons. RESULTS: Pathological staging showed 2 T3cNoMo, 1 T3bNoMo and 2 T3bN1Mo in the patients who underwent cardiopulmonary bypass. There were 5 T3bNoMo, 2 T3bN2Mo, 1 T3bN2M1, 1 T4NoMo and 1 T4N1M1 in the group of patients with infrahepatic thrombus. There were two postoperative deaths. The overall survival rate was poor. Six patients are alive at 3-26 months' follow-up and 9 have died from disease progression. Patients with lymph node involvement or metastasis at the time of diagnosis had a worse survival rate. CONCLUSIONS: Surgical treatment of renal cancer with vena caval extension is specially difficult depending on the level of involvement, which must therefore be determined with precision. MRI is an effective and noninvasive technique. Tumors with thrombus below the suprahepatic veins can be managed by the direct approach with cavotomy. The use of cardiopulmonary bypass is advocated for tumors with suprahepatic caval or atrial extension. Tumors with caval-atrial extension have a negative influence on survival.
