Influence of laparoscopic surgery on the outcomes of radical cystectomy within a multimodal rehabilitation protocol.

INTRODUCTION AND OBJECTIVE: The implementation of Enhanced Recover After Surgery (ERAS) multimodal rehabilitation protocols in radical cystectomy has shown to improve outcomes in hospital stay and complications. The aim of this analysis is to evaluate the impact of laparoscopic surgery on radical cystectomy within a multimodal rehabilitation program. MATERIAL AND METHODS: The study was carried out in a third level center between 2011 and 2020 including patients with bladder cancer submitted to radical cystectomy according to an ERAS (Enhanced Recovery After Surgery) protocol and the Spanish Multimodal Rehabilitation Group (GERM) with 20 items to be fulfilled. RESULTS: A total of 250 radical cystectomies were performed throughout the study period, 42.8% by open surgery (OS) and 57.2% by laparoscopic surgery (LS). The groups are comparable in demographic and clinical variables (p > 0.05). Operative time was longer in the LS group (248.4 ±â€¯55.0 vs. 286.2 ±â€¯51.9 min; p < 0.001). However, bleeding was significantly lower in the LS group (417.5 ±â€¯365.7 vs. 877.9 ±â€¯529.7 cc; p < 0.001), as was the need for blood transfusion (33.6% vs. 58.9%; p < 0.001). Postoperative length of stay (11.5 ±â€¯10.5 vs. 20.1 ±â€¯17.2 days; p < 0.001), total and major complications were also significantly lower in this group (LS). The readmission rate was lower in the LS group but not significantly (36.4% vs. 29.4%; p = 0.237). The difference between 90-day mortality in both groups was not statistically significant (2.8% LS vs. 4.3% OS; p = 0.546). The differences were maintained in the multivariate models. CONCLUSIONS: Laparoscopic surgery within a multimodal rehabilitation program increases operative time but significantly decreases intraoperative bleeding, transfusion requirements, postoperative length of stay, and complications.

La infección del tracto urinario como causa principal de ingreso en pacientes cistectomizados / Urinary tract infection as the main cause of admission in cystectomized patients

Introducción y objetivos: La cistectomía radical con derivación urinaria asociada a linfadenectomía pélvica ampliada continúa siendo el tratamiento de elección en el cáncer vesical musculoinvasivo. Un 64% de los pacientes presentan complicaciones postoperatorias, siendo la infección urinaria responsable en un 20-40% de los casos. El objetivo del presente proyecto es valorar la tasa de infección urinaria como causa de reingreso tras cistectomía, e identificar factores protectores y predisponentes de infección urinaria en nuestro medio. Por último, conocer los resultados obtenidos al aplicar el protocolo de profilaxis antibiótica tras la retirada de los catéteres ureterales.Material y métodosEstudio descriptivo retrospectivo de pacientes cistectomizados en el Servicio de Urología del Hospital Clínico Universitario desde enero de 2012 hasta diciembre de 2018. Desde octubre de 2017, de forma estandarizada, a todo paciente se le aplica un protocolo de prevención de infección del tracto urinario (ITU) tras la retirada de catéteres.ResultadosLa ITU es responsable del 54,7% de los reingresos, siendo un 55,1% de estos por causa de una ITU tras la retirada de los catéteres ureterales. El 9,5% de los pacientes con profilaxis presenta ITU tras la retirada, frente a un 10,6% en el grupo de pacientes sin profilaxis. El paciente que reingresa por ITU tras la retirada tiene un tiempo de catéteres medio de 24,3±7,2 días, frente a los 24,5±7,4 días en el grupo sin ITU (p=0,847).ConclusionesEl tipo de derivación urinaria empleada no guarda relación con la tasa de infección urinaria. El modelo de regresión no identifica la profilaxis antibiótica, ni tampoco el tiempo de catéteres, como factores independientes de ITU tras la retirada de los catéteres. (AU)

Introduction and objectives: Radical cystectomy with urinary diversion associated with extended pelvic lymphadenectomy continues to be the treatment of choice in muscle invasive bladder cancer. Sixty-four percent of patients submitted to this procedure present postoperative complications, with urinary infection being responsible in 20-40% of cases. The aim of this project is to assess the rate of urinary infection as a cause of re-admission after cystectomy, and to identify protective and predisposing factors for urinary infection in our environment. Finally, we will evaluate the outcomes after the establishment of a prophylactic antibiotic protocol after removal of ureteral catheters.Material and methodsRetrospective descriptive study of cystectomized patients in the Urology Service of the Hospital Clínico Universitario of Zaragoza, from January 2012 to December 2018. A urinary tract infection (UTI) prevention protocol after catheter removal is established for all patients since October 2017.ResultsUTI is responsible for 54.7% of readmissions, with 55.1% of these being due to UTI after removal of ureteral catheters. Of the patients who received with prophylaxis, 9.5% presented UTIs after withdrawal, compared to 10.6% in the group of patients without prophylaxis. The patient who is re-admitted for UTI after withdrawal has a mean catheter time of 24.3±7.2 days, compared to 24.5±7.4 days for patients in the group without UTI (P=.847).ConclusionsThe type of urinary diversion performed is not related to the rate of urinary infection. The regression model does not identify antibiotic prophylaxis, nor catheter time, as independent factors of UTI after catheter removal. (AU)

Escroto agudo

El interés del síndrome del escroto agudo en atención primaria radica en la importancia del diagnóstico precoz de una de las posibles causas: la torsión testicular. Se trata de una urgencia subsidiaria de tratamiento quirúrgico en las primeras horas del diagnóstico, ya que la viabilidad del testículo torsionado disminuye conforme aumenta la duración de la torsión. Otras causas de escroto agudo, con las que estableceremos el diagnóstico diferencial, son torsión de los apéndices testiculares, epididimitis, hidrocele, varicocele, traumatismo, etc (AU)

[Surgery of abdominal aortic aneurysm in horseshoe kidney. Report of a case and review of the literature]. / Cirugía del aneurisma de aorta abdominal en presencia de riñón en herradura, a propósito de un caso y revisión de la literatura.

OBJECTIVE: A case of coexistent abdominal aortic aneurysm and horseshoe kidney is presented. The diagnostic difficulties and the different treatments are discussed. METHODS/RESULTS: A 55-year-old male patient with aneurysm of the abdominal aorta associated with a horseshoe kidney is described and the literature is reviewed. The diagnosis was made by CT and arteriography. Treatment was by the transperitoneal approach, division of the renal isthmus and placement of an aortoiliac dacron graft. CONCLUSION: Horseshoe kidney associated with abdominal aortic aneurysm requiring surgical management is uncommon, but when it occurs, aortic repair is significantly more difficult.

[Rectal hemorrhage as a first sign of renal cell adenocarcinoma]. / Rectorragia como primera manifestación de adenocarcinoma de células renales.

Renal cell carcinoma accounts for 85% of all renal primary tumours, the remaining 15% tumours originating either in the renal pelvis or the renal capsule. Clinical signs and symptoms of renal adenocarcinoma can be classified in four groups: specifically urological signs and symptoms, unspecific general symptoms, paraneoplastic syndromes, and metastasis-derived symptoms. The classical triad consists of haematuria, pain and palpable abdominal mass; at present this triad appears in a minority of cases, and is usually a late finding. The number of cases diagnosed from unspecific signs and symptoms is increasingly larger. Routine use of ultrasound and CAT allows a higher number of diagnosis, which frequently occur in the less advanced stages. The present paper presents a case report of renal cell adenocarcinoma, diagnosed from an infrequent early symptom such as rectal bleeding.

Technique and complications of percutaneous nephroscopy: experience with 557 patients in the supine position.

PURPOSE: Percutaneous nephroscopy is usually performed with the patient prone, which is uncomfortable for the patient and does not prevent damage to the colon. We assess the possibility of performing percutaneous nephroscopy using local anesthesia with the patient supine, and evaluate the advantages and complications. MATERIALS AND METHODS: A total of 557 consecutive percutaneous nephroscopies were attempted in 221 men and 242 women in the supine position. Patient age ranged from 8 to 87 years (mean 55.1). Patients are supine with a 3 l. serum bag below the ipsilateral flank. We catheterize the affected uretheral meatus with a 5F catheter through a flexible cystoscope. The tract is infiltrated with local anesthesia. The skin is punctured in the posterior axillary line which corresponds to approximately 1 cm. above the bag. We use an Alken set to dilate the tract to 30F, which is the size of the Amplatz sheath we commonly use. RESULTS: Nephroscopy was performed in 519 cases (93.1%). Mean operation time was 85 minutes (range 15 to 240). Serious bleeding occurred in 3 cases. The colon was never damaged in patients treated in the supine position. CONCLUSIONS: Percutaneous nephroscopy using local anesthesia with the patient supine is safe and easy. According to our experience the advantages in comfort to the patient and feasibility to the surgeon justify its use.

[Wilms' tumor. The experience of the University Clinical Hospital of Zaragoza]. / Tumor de Wilms. Experiencia del Hospital Clínico Universitario de Zaragoza.

OBJECTIVES: The present study reviewed the records of patients with Wilms' tumor treated at the University Hospital of Zaragoza from January, 1980 to January, 1995. METHODS: A retrospective study was conducted in 12 patients (5 boys and 7 girls) with Wilms' tumor, aged 9 months to 9.5 years, with special reference to the clinical symptoms and signs. RESULTS: In 9 of the 12 cases, the tumor was localized to the left kidney and 3 cases had right-sided involvement. No patient showed an unfavorable histological finding, intraoperative rupture or the associated phenotypic manifestations that are frequently described in cases with this tumor type. CONCLUSION: The mortality and survival rates are comparable with those reported by other authors in our country.
