RESUMEN

ABSTRACT BACKGROUND: Kidney transplantation is often regarded as the preferred therapy for end-stage renal disease. Several surgical procedures have been developed to reduce postoperative donor complications, while maintaining kidney quality. OBJECTIVE: This study aimed to compare the preoperative and postoperative outcomes of living kidney donors who underwent either transperitoneal laparoscopic nephrectomy or open nephrectomy. DESIGN AND SETTING: Retrospective study conducted in Istanbul, Turkey. METHODS: Fifty-five living-related kidney donors underwent nephrectomy and were retrospectively divided into two groups: 21 donors who underwent open nephrectomy (Group 1) and 34 donors who underwent transperitoneal laparoscopic nephrectomy (Group 2). RESULTS: In comparison to the donors who underwent open nephrectomy, those who underwent transperitoneal laparoscopic nephrectomy had significantly shorter postoperative hospital stays (2.3 ± 0.2 versus 3.8 ± 0.8 days, P = 0.003), duration of urinary catheterization (1.2 ± 0.8 days versus 2.0 ± 0.7 days, P = 0.0001), operating times (210 ± 27 minutes versus 185 ± 24 minutes, P = 0.02), and less blood loss (86 ml versus 142 ml, P = 0.048). There was no statistically significant difference between the two groups with regard to the estimated blood transfusion and warm ischemia time. The preoperative week, first postoperative week, and 1-month postoperative serum creatinine levels were comparable between the groups. CONCLUSIONS: Laparoscopic donor nephrectomy can be safely performed at centers with expertise in laparoscopic surgery. Laparoscopic donor nephrectomy has better outcomes than open donor nephrectomy in terms of length of hospital stay, duration of urinary catheterization, operating time, and blood loss.

RESUMEN

El abordaje laparoscópico para la nefrectomía del donante vivo, ha representado en los últimos años un paradigma con resultados comparables e incluso superiores al abordaje abierto. Objetivo: Evaluar el abordaje laparoscópico en la nefrectomía de donante vivo como procedimiento de elección en el trasplante renal. Métodos: Entre los meses de enero y octubre de 2010, se evaluaron de manera prospectiva 13 pacientes donantes vivos de riñón, sometidos a nefrectomía laparoscópica para trasplante renal en el Hospital Dr. Miguel Pérez Carreño. Resultados: La sobrevida de los pacientes y del órgano fue de 100 %, sin necesidad de conversión en ningún caso. La edad promedio de los donantes fue de 33,8 años, el tiempo quirúrgico promedio fue 187 min, el tiempo de isquemia caliente promedio fue 4,31 min. En el 15,4 % de los pacientes se encontraron variantes anatómicas y en el 23,1 % se presentaron complicaciones intraoperatorias resueltas sin inconvenientes. La estancia hospitalaria fue 3,6±1,4 días. El promedio del dolor postoperatorio (EVA) fue de 5,9 durante el primer día con descenso a 2,1 en el tercero. Conclusiones: La nefrectomía laparoscópica en donantes vivos es una técnica reproducible que requiere de instrumental adecuado y personal entrenado, demuestra sus ventajas en cuanto a disminución de sangrado, dolor postoperatorio, complicaciones y estancia hospitalaria(AU)

RESUMEN

Background: Live Donor Laparoscopic Nephrectomy (LDLN) has substantial benefits when compared with open nephrectomy such as shorter hospital stay, prompt return to work, less post-operative pain, better cosmetic results, less blood loss and less surgical wound infections. It is the mode of choice for safely harvesting a kidney for organ transplantation. Aim: To describe the surgical results of LDLN in a pioneer renal transplant center in Chile. Material and Methods: Review of clinical records of 75 subjects aged 27 to 60 years (37 males) subjected to a LDLN in a public hospital between 1998 and 2013. Information about clinical and surgical data and perioperative complications was retrieved. Results: No subject died. All kidneys were satisfactorily implanted in their receptors. The mean operative time was 116 minutes. Mean hospital stay was 1.6 days, warm ischemia time was 6.8 minutes, and cold ischemia time was 31.5 minutes. Operative adverse events occurred in 8 percent. The conversion and reoperation rates were 4 and 1.3 percent, respectively. Among receptors, 1.5 percent evolved with Acute Tubular Necrosis and 2.2 percent required graft excision. Conclusions: LDLN is a safe and pioneering surgical technique in Chile. Its results are satisfactory and comparable to those obtained with classic lumbotomy.


Introducción: El trasplante renal es en la actualidad el tratamiento de elección de la Insuficiencia Renal Crónica Terminal. La Nefrectomía Laparoscópica del Donante Vivo (NLDV) tiene ventajas sustanciales en relación a la Nefrectomía Clásica. Entre estas se destacan una menor estancia hospitalaria, pronto regreso a la actividad laboral, disminución del dolor post-operatorio, mejores resultados cosméticos, menor pérdida de volumen sanguíneo y una disminución de infecciones de heridas operatorias, consolidándose como la primera prioridad como forma de obtener un órgano para trasplante renal. El presente trabajo tiene como objetivo mostrar la casuística y complicaciones en el Hospital Barros Luco-Trudeau (HBLT), como centro pionero en NLDV en nuestro país. Material y Método: Estudio retrospectivo de corte transversal. Se realiza una revisión de registros clínicos de 75 NLDV realizadas entre 1998-2013, seleccionando datos demográficos, clínicos y quirúrgicos de donantes y receptores, con un especial énfasis en relación a complicaciones peri-operatorias. Resultados: Sin mortalidad. Todos los riñones fueron implantados satisfactoriamente en sus respectivos receptores. Cirugía con duración promedio de 116 min, estadía hospitalaria promedio de 1,6 días, isquemia caliente promedio de 6,8 min e isquemia fría promedio de 31,5 min. Incidentes operatorios 8 por ciento y 4 por ciento conducentes a conversión. Tasa de reoperación de 1,3 por ciento. En cuanto a receptores, un 1,5 por ciento desarrolla Necrosis Tubular Aguda. 2,2 por ciento requiere transplantectomía. Discusión: La NLDV representa una técnica segura, que ha llegado a constituir el 100 por ciento de las nefrectomías de donantes vivos realizadas durante los últimos tres años. Los resultados son satisfactorios y plenamente comparables a los resultados obtenidos por lumbotomía clásica y de otros centros de alto volumen laparoscópico a nivel internacional.

RESUMEN

Objective To analyze the clinical value of 16-row multislice CT in the live kidney donor preoperative assessment. Methods Thirty-six kidney donors underwent 16-slice CT preopera-tive assessment. The non-enhanced, arterial phase, venous phase and excretory phase examinations were performed. Two radiologists independently studied renal vessels and urinary system of each case by maximum intensity projections and volume rendering techniques. The specificity and accuracy of 16-row muhislice CT in the evaluation o{ renal vessels and urinary system were calculated after comparing with surgical findings as reference. Results 16-row muhislice CT found 7 variant renal arteries. One variant artery confirmed in surgery was missed in the CT study. 16-row muhislice CT made cor-rect diagnosis of all variant anatomy of renal veins and ureters which were confirmed in surgery. For i-dentification of variant anatomy of renal arteries, veins and ureters, the specificity of 16-slice CT was 100% (29/29), 100% (32/32), and 100% (35/35), the overall accuracy was 97%(36/37), 100% (36/ 36), and 100%(36/36), respectively. Conclusions 16-row muhislice CT shows excellent value in the evaluation of renal vessels and urinary system in live kidney donors. 16-row multislice CT is suit-able for the noninvasive examination in live kidney donor preoperative assessment and provides all sup-portive and relevant information required by the surgeons.

RESUMEN

PURPOSE: Laparoscopic living donor nephrectomy has recently been emerged as a very attractive measure to the standard open surgical procedure for kidney transplantation (KTx) because of many advantages. But it also has some disadvantages such as technical difficulty, impaired early graft function and expensiveness. To overcome this shortcomings, we developed a new surgical method of retroperitoneoscopy assisted live donor nephrectomy. The method has been reported as an attractive surgical methods with many advantages to donor. But, recipient`s outcome is also equally important in living donor kidney transplantation. METHODS: We retrospectively studied recipient`s outcome between patients who received living donor kidneys from conventional open nephrectomies (Group I, n=247) and retroperitoneoscopy assisted nephrectomies (Group II, n=82) at our institution from March 1, 1997 and July 30, 2000. We compared postoperative complication, patient and graft survival and graft function between two groups for 12 months retrospectively. RESULTS: Demographic data such as age, sex, kidney weight/body weight ratio; ABO compatibility; degree of HLA matching and method of immunosuppression were not different between two groups (p>0.05). Complications, such as delayed graft function, acute rejection, ureter complication, graft failure, patients motality were not different. For the evaluation of graft function, we measured serum creatinine level for 12 months after trasplantation. There also was no difference of graft function between two groups. CONCLUSION: Recipient's outcome in patient received kidney by retroperitoneoscopy assisted live donor nephrectomy was similar to those of patient received kidney by conventional operation.
