Hand-assisted laparoscopic retroperitoneal donor nephrectomy: A single-institution experience of over 500 cases-Operative technique and clinical outcomes

Robotic donor nephrectomy: optimizing outcomes beyond the limitations of laparoscopy

BACKGROUND

Robotic donor nephrectomy (RDN) has emerged as a safe alternate to laparoscopic donor nephrectomy (LDN), offering improved visualization, instrument dexterity and ergonomics. There is still concern about how to safely transition from LDN to RDN.

METHODS

We performed a retrospective review of 150 consecutive living donor operations (75 LDN and 75 RDN) at our center, comparing the first 75 RDN's with the last 75 LDN's performed prior to the initiation of the robotic transplant program. Operative times and complications were used as surrogates of efficiency and safety, respectively, to estimate the learning curve with RDN.

RESULTS

RDN was associated with a longer total operative time (RDN 182 vs LDN 144 min; P < 0.0001) but a significantly shorter post-operative length of stay (RDN 1.8 vs LDN 2.1 days; P = 0.0213). Donor complications and recipient outcomes were the same between both groups. Learning curve of RDN was estimated to be about 30 cases.

CONCLUSIONS

RDN is a safe alternate to LDN with acceptable donor morbidity and no negative impact on recipient outcomes even during the early part of the RDN learning curve. Surgeon preferences for the robotic approach compared to traditional laparoscopy will require further scrutiny to improve ergonomics and operative efficiency.

Hand port-site infection after hand-assisted laparoscopic donor nephrectomy for living-donor kidney transplantation: a retrospective cohort study

Background

Hand-assisted laparoscopic donor nephrectomy (HALDN) is widely performed to minimize burden on living kidney donors. However, hand port-site infections after HALDN may occur. This study aimed to assess the impact of donor characteristics including preoperative comorbidities and operative factors on hand port-site infection after HALDN.

Methods

In this single-center, retrospective cohort study, 1,260 consecutive HALDNs for living-donor kidney transplantation performed between January 2008 and December 2021 were evaluated. All living donors met the living kidney donor guidelines in Japan. Hand port-site infections were identified in 88 HALDN cases (7.0%). To investigate risk factors for hand port-site infection, donor characteristics including preoperative comorbidities such as hypertension, glucose intolerance, dyslipidemia, obesity, and operative factors such as operative duration, blood loss, preoperative antibiotic prophylaxis, and prophylactic subcutaneous suction drain placement at the hand port-site were analyzed using logistic regression analysis.

Results

In the multivariate analysis, significant differences were identified regarding sex (P = 0.021; odds ratio [OR], 1.971; 95% confidence interval [CI], 1.108-3.507), preoperative antibiotic prophylaxis (P < 0.001; OR, 0.037; 95% CI [0.011-0.127]), and prophylactic subcutaneous suction drain placement at the hand port-site (P = 0.041; OR, 2.005; 95% CI [1.029-3.907]). However, a significant difference was not identified regarding glucose intolerance (P = 0.572; OR, 1.148; 95% CI [0.711-1.856]). Preoperative comorbidities may not cause hand port-site infections within the donors who meet the living kidney donor guidelines. Preoperative antibiotic prophylaxis is crucial in preventing hand port-site infection, whereas prophylactic subcutaneous suction drain placement may increase the risk of hand port-site infection.

Nefrectomía laparoscópica en un programa de donante vivo en la Costa Caribe de Colombia

La nefrectomía laparoscópica en donante vivo es la mejor opción en el proceso del trasplante para pacientes con enfermedad renal crónica en estadio cuatro y cinco. El objetivo del artículo es describir la experiencia en el programa de donante vivo de riñón entre el 2013 y el 2018 en Colombiana de Trasplantes en la costa Caribe colombiana. Se realizó un estudio descriptivo que incluyó una muestra consecutiva de 55 donantes vivos de riñón operados por Colombiana de Trasplantes, entre enero de 2013 y enero de 2018; se llevó a cabo el análisis estadístico de las variables relevantes. La media de la edad fue de 41 años. El 57,4% de los donantes fueron mujeres. El tiempo de cirugía tuvo una media de 1,9 horas. Ninguno de los pacientes falleció en el seguimiento a los seis meses y el promedio de la estancia hospitalaria posterior a la cirugía fue de dos días. Las variables relevantes y los desenlaces de los pacientes son similares a los de otros grupos de trasplantes, sin embargo, hay características específicas que pueden ayudar a mejorar las estrategias en salud en la costa Caribe colombiana.
