Non-simultaneous kidney exchange cycles in resource-restricted countries without non-directed donation - a prospective single-center cohort study.

Recent reports suggest that bridge-donor reneging is rare (1.5%) in non-simultaneous kidney exchange chains. However, in developing countries, the non-directed donors who would be needed to initiate chains are unavailable, and furthermore, limited surgical space and resources restrain the feasibility of simultaneous kidney exchange cycles. Therefore, the aim of this study was to evaluate the bridge-donor reneging rate during non-simultaneous kidney exchange cycles (NSKEC) in a prospective single-center cohort study (n = 67). We describe the protocol used to prepare co-registered donor-recipient pairs for non-simultaneous surgeries, in an effort to minimize the reneging rate. In addition, in order to protect any recipients who might be left vulnerable by this arrangement, we proposed the use of standard criteria deceased-donor kidneys to rectify the injustice in the event of any bridge-donor reneging. We report 17 successful NSKEC resulting in 67 living-donor kidney transplants (LDKT) using 23 bridge-donors without donor renege and no intervening pairs became unavailable. We propose that NSKEC could increase LDKT, especially for difficult-to-match sensitized pairs (25 of our 67 pairs) in countries with limited transplantation resources. Our study confirms that NSKEC can be safely performed with careful patient-donor selection and non-anonymous kidney exchanges.

Past, present and future of kidney paired donation transplantation in India.

One third of healthy willing living kidney donors are rejected due to ABO blood group incompatibility and donor specific antibody. This increases pre-transplant dialysis duration leading to increased morbidity and mortality on the kidney transplantation waiting list. Over the last decade kidney paired donation is most rapidly increased source of living kidney donors. In a kidney transplantation program dominated by living donor kidney transplantation, kidney paired donation is a legal and valid alternative strategy to increase living donor kidney transplantation. This is more useful in countries with limited resources where ABO incompatible kidney transplantation or desensitization protocol is not feasible because of costs/infectious complications and deceased donor kidney transplantation is in initial stages. The matching allocation, ABO blood type imbalance, reciprocity, simultaneity, geography were the limitation for the expansion of kidney paired donation. Here we describe different successful ways to increase living donor kidney transplantation through kidney paired donation. Compatible pairs, domino chain, combination of kidney paired donation with desensitization or ABO incompatible transplantation, international kidney paired donation, non-simultaneous, extended, altruistic donor chain and list exchange are different ways to expand the donor pool. In absence of national kidney paired donation program, a dedicated kidney paired donation team will increase access to living donor kidney transplantation in individual centres with team work. Use of social networking sites to expand donor pool, HLA based national kidney paired donation program will increase quality and quantity of kidney paired donation transplantation. Transplant centres should remove the barriers to a broader implementation of multicentre, national kidney paired donation program to further optimize potential of kidney paired donation to increase transplantation of O group and sensitized patients. This review assists in the development of similar programs in other developing countries.

Anesthetic management of two cases of Bardet-Biedl syndrome for renal transplantation.

Bardet-Biedl syndrome (BBS) is a multisystem autosomal recessive disorder with clinical and genetic heterogeneity. It is a type of ciliopathy characterized by retinal dystrophy, central obesity, polydactyly, cognitive impairment, and gonadal and renal dysgenesis. It has been suggested that the involved proteins attach to the basal body of ciliated cells making this a disorder of ciliary dysfunction. We report two cases of typical BBS in a 17-year-old female and 29-year-old male patient, who presented for live-related renal transplant. We discuss the relevant points of the syndrome regarding anesthetic management.

Impact of single centre kidney paired donation transplantation to increase donor pool in India: a cohort study.

In a living donor kidney transplantation (LDKT) dominated transplant programme, kidney paired donation (KPD) may be a cost-effective and valid alternative strategy to increase LDKT in countries with limited resources where deceased donation kidney transplantation (DDKT) is in the initial stages. Here, we report our experience of 300 single-centre KPD transplantations to increase LDKT in India. Between January 2000 and July 2016, 3616 LDKT and 561 DDKT were performed at our transplantation centre, 300 (8.3%) using KPD. The reasons for joining KPD among transplanted patients were ABO incompatibility (n = 222), positive cross-match (n = 59) and better matching (n = 19). A total of 124 two-way (n = 248), 14 three-way (n = 42), one four-way (n = 4) and one six-way exchange (n = 6) yielded 300 KPD transplants. Death-censored graft and patient survival were 96% (n = 288) and 83.3% (n = 250), respectively. The mean serum creatinine was 1.3 mg/dl at a follow-up of 3 ± 3 years. We credit the success of our KPD programme to maintaining a registry of incompatible pairs, counselling on KPD, a high-volume LDKT programme and teamwork. KPD is legal, cost effective and rapidly growing for facilitating LDKT with incompatible donors. This study provides large-scale evidence for the expansion of single-centre LDKT via KPD when national programmes do not exist.

Increasing access to kidney transplantation for sensitized recipient through three-way kidney paired donation with desensitization: The first Indian report.

The combination of kidney paired donation (KPD) with desensitization represents a promising method of increasing the rate of living donor kidney transplantation (LDKT) in immunologically challenging patients. Patients who are difficult to match and desensitize due to strong donor specific antibody are may be transplanted by a combination of desensitization and KPD protocol with more immunologically favorable donor. We present our experience of combination of desensitization protocol with three-way KPD which contributed to successful LDKT in highly sensitized end stage renal disease patient. All recipients were discharged with normal and stable allograft function at 24 mo follow up. We believe that this is first report from India where three-way KPD exchange was performed with the combination of KPD and desensitization. The combination of desensitization protocol with KPD improves access and outcomes of LDKT.

Ultrasound guided peritubal infiltration of 0.25% Bupivacaine versus 0.25% Ropivacaine for postoperative pain relief after percutaneous nephrolithotomy: A prospective double blind randomized study.

BACKGROUND AND AIM: Percutaneous nephrolithotomy (PCNL) is a common for managing renal calculi. Pain in the initial post operatie period is relieved by infiltration of local anaesthetic around the nephrostomy tract. We aimed to compare the analgesic efficacy of bupivacaine and ropivacaine. METHODS: A total of 100 adult patients undergoing elective PCNL-under balanced general anaesthesia were randomly divided into bupivacaine group (Group B) and ropivacaine group (Group R). After completion of procedure, 23G spinal needle was inserted at 6 and 12 O'clock position under ultrasonic guidance up to renal capsule along the nephrostomy tube. A volume of 10 ml of either 0.25% bupivacaine or 0.25% ropivacaine solution was infiltrated in each tract while withdrawing the needle. Post-operative pain was assessed using visual analogue scale (VAS) and dynamic visual analogue scale (D-VAS) for initial 24 h. Intravenous tramadol was given as rescue analgesia when VAS >4. Time to first rescue analgesic, number of doses and total amount of tramadol required in initial 24 h and side-effects were noted. RESULTS: Visual analogue scale and D-VAS at 6 h and 8 h in Group B was significantly higher than Group R. Mean time to first rescue analgesia in Group R was significantly longer than Group B. Mean number of doses of tramadol and total consumption of tramadol in 24 h was less in Group R, though not statistically significant. CONCLUSION: Peritubal infiltration of 0.25% ropivacaine infiltration along the nephrostomy tract is more effective than 0.25% bupivacaine in alleviating initial post-operative pain after PCNL.

Outcome of renal transplantation from deceased donors: experience from developing country.

BACKGROUND: In India, there are a large number of end-stage renal disease (ESRD) patients waiting for renal transplantation (RT). Organ retrieval from brain dead deceased donor (DD) is getting increased attention as the waiting list for organ recipients far exceeds the organ donor pool. In our country, despite a large population, the number of brain dead donors undergoing organ donation is very less. DDRT is the possible solution to bridge the disparity between organ supply and demand. In India, the potential for DDRT is huge due to the high number of fatal road traffic accidents and this pool is yet to be tapped. PATIENTS AND METHODS: We report DDRT outcome in 294 patients (age: 36.5 ± 14.1 years; male:female, 200:94) between 2005 and 2012. All patients received single-dose rabbit-anti-thymocyte globulin for induction and steroids, calcineurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. RESULTS: Our retrospective study in 294 DDRT shows a fairly successful outcome. Over a mean follow-up of 3.93 years, patient and graft survival rates were 81.7% and 92.6%, respectively, with a median serum creatinine of 1.5 mg/dL. 20.7% had biopsy-proven acute rejection. CONCLUSION: Given the widespread organ shortage, DDRT has a potential to expand the donor pool and shorten the waiting list for RT, encouraging the use of this approach even in low-income countries. Aggressive donor management, increasing public awareness about the concept of organ donation, good communication between clinician and the family members, and a well-trained team of transplant coordinators can help in improving the number of organ donations.

Anaesthetic consideration during laparoscopic bilateral simultaneous nephrectomy.

STUDY OBJECTIVE: To assess outcome from anaesthesia during laparoscopic bilateral simultaneous nephrectomy. DESIGN: Retrospective study. MEASUREMENTS: Preoperative Hb%, serum potassium, coagulation profile electrocardiography (ECG) changes, 2D Echography, x-ray chest, haemodynamic changes, end-tidal carbon dioxide (EtCO2), fluid management and postoperative analgesia. RESULTS: The mean age was 24.75 ± 14.35 years. The mean duration of surgery was 120 ± 80 minutes. The Hb%, serum creatinine and serum potassium were 9.4 ± 1.04%, 6.79 ± 4.91 meq/L and 3.61 ± 0.51 meq/L, respectively. Pulse rate mean blood pressure and EtCO2 were recorded after creation of pneumoperitoneum and at 15, 30, 45 and after exsufflation of pneumoperitoneum. After pneumoperitoneum, there was increase in pulse rate, systolic blood pressure, diastolic blood pressure and EtCO2. After 30 minutes and throughout the surgery, these variables remained stable. Four patients required nitroglycerine infusion for intraoperative hypertention. Only one patient required packed cell volume (PCV) transfusion and total intravenous fluid was 1 ± 0.5 L. At the time of exsufflation, there was decrease in pulse rate, systolic and diastolic blood pressure and EtCO2. CONCLUSION: Because of advancement in anaesthetic agents and muscle relaxant, there is safe outcome from anaesthesia during laparoscopic bilateral simultaneous nephrectomy.

Ultrasound guided peritubal infiltration of 0.25% ropivacaine for postoperative pain relief in percutaneous nephrolithotomy.

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is a common endourologic procedure with less morbidity than open surgery. However, pain around the nephrostomy tube requires good post operative analgesia. So we hypothesize that infiltration of local anesthetic from the renal capsule to the skin around the nephrostomy tract would relieve the pain in the initial postoperative period. METHODS: 60 adult patients of either sex with ASA physical status I to III and undergoing percutaneous nephrolithotomy were randomized for a prospective double-blind controlled study. Patients were divided into control group (n = 30) and ropivacaine group (n = 30). Balanced general anesthesia was given. After completion of surgical procedure, 23 gauge spinal needle was inserted at 6 and 12 o'clock position under ultrasonic guidance up to therenal capsule along the nephrostomy tube. 10 ml of 0.25% ropivacaine or normal saline solution was infiltrated in each tract while withdrawing the needle from renal capsule to the skin. Post-operative pain was assessed using visual analogue scale (VAS) and dynamic visual analogue scale (D-VAS) during deep breathing and coughing on a scale of 0-10 during the initial postoperative 24 hours. Rescue analgesia was given in the form of injection tramadol 1.0 mg/kg intravenously when VAS > 4 and maximum up to 400mg in 24 hours. Time to first rescue analgesic, number of doses of tramadol and total amount of tramadol required in the initial postoperative 24 hours were noted. Patients were observed for any side effect and treated accordingly. RESULTS: VAS at rest (VAS) as well as during deep breathing and coughing (DVAS) were significantly lower in ropivacaine group during first 24 hours. Mean time to 1st rescue analgesic in ropivacaine group was longer (10.7 +/- 2.64 hours) as compared to control group (2.05 +/- 1.44 hours) (P = 0.0001). Mean number of doses of tramadol in 24 hours in group-R were less (2.25 +/- 0.51) than group-C (4.4 +/- 0.68) (P = 0.0001). The mean total amount of tramadol in 24 hours in group-R was significantly lower than group-C. Side effects like nausea and vomiting and sedation were minimum and non-significant in both groups. CONCLUSION: Local anesthetic infiltration of 0.25% ropivacaine along the nephrostomy tract is efficient in alleviating post-operative pain after percutaneous nephrolithotomy surgery. The number of doses and total consumption of rescue analgesic were also decreased in the initial postoperative 24 hours.

Ten kidney paired donation transplantation on World Kidney Day 2013: raising awareness and time to take action to increase donor pool.

BACKGROUND: Kidney paired donation (KPD) is feasible for any center that performs living related donor renal transplantation (LRDRTx). Lack of awareness, counseling and participation are important hurdles in KPD patients with incompatible donors. MATERIALS AND METHODS: This is an institutional review board approved study of 10 ESRD patients who consented to participate in the KPD transplantation at our center. All the surgeries were carried out on the same day at the same center on the occasion of World Kidney Day (WKD) (14 March 2013). All recipients had anatomic, functional and immunological similar donors. RESULTS: KPD were performed to avoid blood group incompatibility (n = 8) or to avoid a positive crossmatch (n = 2). None of the patients experienced delayed graft function and surgical complications. At 3 month follow-up, median serum creatinine was 1 (range 0.6 to 1.25) mg/dL and two patients developed allograft biopsy-proven acute rejection and responded to antirejection therapy. Due to impact of our awareness activity, 20 more KPD patients are medically fit for transplantation and waiting for permission from the authorization committee before transplantation. CONCLUSION: This is a report of 10 simultaneous KPD transplantations in a single day in a single centre on WKD raising awareness of KPD. KPD is viable, legal and rapidly growing modality for facilitating LRDRTx for patients who are incompatible with their healthy, willing LRD.

Analgesic efficacy of peritubal infiltration of ropivacaine versus ropivacaine and morphine in percutaneous nephrolithotomy under ultrasonic guidance.

BACKGROUND AND PURPOSE: Percutaneous nephrolithotomy is a safe and effective endourologic procedure which is less morbid than open surgery. However, pain around a nephrostomy tube requires good post-operative analgesia. We hypothesize that infiltration of local anesthetic with opioid from the renal capsule to the skin around the nephrostomy tract under ultrasonic guidance would alleviate the postoperative pain for a long period. METHODS: A total of 60 ASA physical status I to II patients were selected for a prospective randomized double-blind controlled study in percutaneous nephrolithotomy surgeries. Patients were divided into group R (n=30) and group RM (n=30). Balanced general anesthesia was given. After completion of the surgical procedure, a 23-gauze spinal needle was inserted at 6 and 12 O'clock position under ultrasonic guidance up to renal capsule along the nephrostomy tube. A 10 ml drug solution was infiltrated in each tract while withdrawing from renal capsule to the skin. After extubation, the patient was shifted to the post-anesthesia care unit for 24 hours. Post-operative pain was assessed using the visual analog scale (VAS) and dynamic visual analog scale (DVAS) (during deep breathing and coughing) rating 0-10 for initial 24 hours. Rescue analgesia was given in the form of injection tramadol 1.0 mg/kg intravenously when VAS ≥4 and maximum up to 400 mg in 24 hours. Time to 1(st) rescue analgesic, number of doses of tramadol and total consumption of tramadol required in initial 24 hours were noted. Patients were observed for any side effect and treated accordingly. RESULTS: Time to 1(st) rescue analgesic, i.e., duration of analgesia in group RM is more prolonged than group R (P=0.0004). The number of doses of tramadol in 24 hours in group R were higher as compared to group RM (P=0.0003). The total amount of tramadol in 24 hours in group R was more than in group RM (P=0.0013). Side effects like nausea and vomiting and sedation were comparable in both the groups. CONCLUSION: Addition of morphine to ropivacaine for nephrostomy tract infiltration significantly prolonged the duration of post-operative analgesia and reduced the number of doses and total consumption of rescue analgesic in initial 24 hours in percutaneous nephrolithotomy surgery.

The analgesic efficacy of peritubal infiltration of 0.25% bupivacaine in percutaneous nephrolithotomy - A prospective randomized study.

BACKGROUND: Percutaneous nephrolithotomy is a routine endourologic procedure in patients with renal stones. Although it is less painful than open surgery, good postoperative analgesia is required to alleviate pain around nephrostomy tube. MATERIALS AND METHODS: Sixty ASA grade I patients, 18 to 60 years of age, of either sex were randomized to receive 20 ml of 0.25% bupivacaine (group S) or 20 ml of normal saline (group C) through 23-gauge spinal needle along the nephrostomy tube under fluroscopic guidance at the end of the surgery. Postoperative pain score was assessed by visual and dynamic visual analog scores. When the scores were ≥4, rescue analgesia was given in the form of tramadol 1 mg/kg i.v. upto maximum 400 mg in 24 hours. Time to first demand analgesia and total dose of tramadol in first 24 hours was noted. RESULTS: Pain scores at rest and during coughing as well as rescue analgesic requirements for first 24 hours were significantly less in the bupivacaine group than those of the control group (P < 0.05). The first request for demand analgesia was around 9 hours in group S, while in group C it was around 2.6 hours (P < 0.05). Total requirement of tramadol in group S was 119.3 mg and in C group it was 276.8 mg (P < 0.05). CONCLUSION: Peritubal infiltration of 0.25% bupivacaine is efficient in alleviating postoperative pain after PCNL.
