Shift from severe hypotension to salt-dependent hypertension in a child with autosomal recessive polycystic kidney disease after bilateral nephrectomies: a case report.

BACKGROUND: Autosomal recessive polycystic kidney disease (ARPKD) is a significant cause of morbidity and mortality in infants and children. In severe cases bilateral nephrectomies are considered but may be associated with significant neurological complications and life-threatening hypotension. CASE PRESENTATION: We describe a case of a 17 months old boy with genetically confirmed ARPKD who underwent sequential bilateral nephrectomies at the age of 4 and 10 months. Following the second nephrectomy the boy was started on continuous cycling peritoneal dialysis with blood pressure on the lower range. At the age of 12 months after a few days of poor feeding at home the boy experienced a severe episode of hypotension and coma of Glasgow Come Scale of three. Brain magnetic-resonance imaging (MRI) showed signs of hemorrhage, cytotoxic cerebral edema and diffuse cerebral atrophy. During the subsequent 72 h he developed seizures requiring anti-epileptic drug therapy, gradually regained consciousness but remained significantly hypotensive after discontinuation of vasopressors. Thus, he received high doses of sodium chloride orally and intraperitoneally as well as midodrine hydrochloride. His ultrafiltration (UF) was targeted to keep him in mild-to-moderate fluid overload. After two months of stable condition the patient started to develop hypertension requiring four antihypertensive medications. After optimizing peritoneal dialysis to avoid fluid overload and discontinuation of sodium chloride the antihypertensives were discontinued, but hyponatremia with hypotensive episodes reoccurred. Sodium chloride was reintroduced resulting in recurrent salt-dependent hypertension. CONCLUSIONS: Our case report illustrates an unusual course of blood pressure changes following bilateral nephrectomies in an infant with ARPKD and the particular importance of tight regulation of sodium chloride supplementation. The case adds to the scarce literature about clinical sequences of bilateral nephrectomies in infants, and as well highlights the challenge of managing blood pressure in these patients. Further research on the mechanisms and management of blood pressure control is clearly needed.

Predominant Liver Cystic Disease in a New Heterozygotic PKHD1 Variant: A Case Report.

BACKGROUND The polycystic kidney and hepatic disease 1 (PKHD1) gene codes for fibrocystin-polyductin, a protein that takes part in cell-signaling for cell differentiation, especially in kidney tubules and bile ducts. A homozygous or compound heterozygous defect in this gene can cause autosomal recessive polycystic kidney disease (ARPKD). Polycystic liver disease (PCLD) can also be caused by single heterozygous variants in the PKHD1 gene. ARPKD presents with renal insufficiency and cystic dilatation of bile ducts, although disease is not expected with a single heterozygous mutation. PCLD presents with multiple cysts in the liver and dilated bile ducts as well, but with less of an impact on the kidneys than with ARPKD. Our purpose in publishing this report is to introduce an as-yet unknown variant to the body of genetic defects associated with ARPKD and PCLD, as well as to argue for the likely pathogenicity of the variant according to the prevailing criteria used for classifying gene variants. CASE REPORT We present a patient with a de novo PKHD1 variant currently classified as a variant of unknown significance manifesting with bilaterally enlarged cystic kidneys and echogenic cystic structures in the hepatic portal system, indicative of cystic disease. CONCLUSIONS Given this patient's liver and kidney presentation that does not fully align with either ARPKD or PCLD, the authors believe that the single heterozygous variant in this patient's PKHD1 gene is worthy of reporting. This new single heterozygous variant in PKHD1 gene causing cystic kidney and cystic hepatic disease in the patient should be considered 'likely pathogenic' according to the criteria set by the American College of Medical Genetics.

Kidney concentrating capacity in children with autosomal recessive polycystic kidney disease is linked to glomerular filtration and hypertension.

BACKGROUND: Impaired kidney concentration capacity is present in half of the patients with autosomal dominant polycystic kidney disease (ADPKD). The kidney concentrating capacity was further impaired within the animal model of autosomal recessive polycystic kidney disease (ARPKD). To date, only one small study has investigated it in children having ARPKD. Therefore, we aimed to study the kidney concentrating ability in a larger cohort of children with ARPKD. METHODS: Eighteen children (median age 8.5 years, range 1.3-16.8) were retrospectively investigated. A standardized kidney concentrating capacity test was performed after the application of a nasal drop of desmopressin (urine osmolality > 900 mOsmol/kg). The glomerular filtration rate was estimated using the Schwartz formula (eGFR) and blood pressure (BP) was measured as office BP. RESULTS: Kidney concentrating capacity was decreased (urine osmolality < 900 mOsmol/kg) in 100% of children with ARPKD. The median urine osmolality after desmopressin application was 389 (range 235-601) mOsmol/kg. Sixteen patients (89%) were defined as hypertensive based on their actual BP level or their use of antihypertensive drugs. The maximum amounts of urinary concentration correlated significantly with eGFR (r = 0.72, p < 0.0001) and hypertensive scores (r = 0.50, p < 0.05), but not with kidney size. Twelve patients (67%) were defined as having CKD stages 2-4. The median concentrating capacity was significantly lower in children within this group, when compared to children with CKD stage 1 possessing a normal eGFR (544 mOsmol/kg, range 413-600 mOsmol/kg vs. 327 mOsmol/kg, range 235-417 mOsmol/l, p < 0.001). CONCLUSIONS: Impaired kidney concentrating capacity is present in most children with ARPKD and is associated with decreased eGFR and hypertension.

Liver and spleen volume and stiffness in patients post-Fontan procedure and patients with ARPKD compared to normal controls.

PURPOSE: Both congestive (patients post-Fontan hepatopathy) and congenital (patients with ARPKD) disease can lead to hepatic fibrosis and portal hypertension with eventual development of splenomegaly. We investigated liver and spleen stiffness as measured by MRE between post-Fontan, ARPKD patients and controls independent of organ volume. METHODS: Our study included 122 subjects (70 Fontan patients, 14 ARPKD patients, and 38 controls). The mean MRE liver and spleen stiffness values of Fontan patients and patients with ARPKD were compared to controls. Similarly, the liver and spleen volumes of the Fontan patients and patients with ARPKD were then compared to the volumes of controls. RESULTS: Post-Fontan and ARPKD patients, mean liver stiffness, mean liver volume as well as mean spleen stiffness and mean spleen volume were higher than mean liver stiffness, mean liver volume, mean spleen stiffness, and mean spleen volume of controls. While liver stiffness correlated to liver volume in controls, we found no correlation between stiffness and volume in either Fontan or ARPKD patients, which indicates MRE's ability to act as an independent biomarker. However, these findings are not true in the spleen, where there is significant association between volume and stiffness in patients with ARPKD, but not in Fontan patients or controls. CONCLUSION: Liver and spleen stiffness and volumes are significantly different among Fontan patients, ARPKD patients, and controls. Our findings suggest that beyond diagnosing fibrosis, MRE cut-off values could be disease-specific since not only the severity but the underlying pathology causing organ congestion or fibrosis influences MRE results.

Ambulatory blood pressure and hypertension control in children with autosomal recessive polycystic kidney disease: clinical experience from two central European tertiary centres.

OBJECTIVE: : Arterial hypertension is a common complication in patients with autosomal recessive polycystic kidney disease (ARPKD), occurring in 33-75% of children when measured by office blood pressure (OBP). Ambulatory blood pressure monitoring (ABPM) is a superior tool for investigating blood pressure relative to OBP. The aim of our study was to investigate the prevalence and control of hypertension in children with ARPKD based on ABPM. METHODS: This retrospective study evaluated 36 children with ARPKD and at least one ABPM performed in two our tertiary paediatric nephrology centres and 29 children with at least two ABPM. Ambulatory hypertension was defined as mean daytime or night-time BP at least 95th percentile or use of antihypertensives and controlled hypertension as normal ambulatory BP in children on antihypertensive drugs. RESULTS: The first ABPM study revealed ambulatory hypertension in 94% of children. Untreated or uncontrolled ambulatory hypertension was diagnosed in 67% and controlled hypertension in only 28%. Masked hypertension was found in 5.5% and white-coat hypertension in 14%. The last ABPM study revealed ambulatory hypertension in 86% (all 86% hypertensive children on drugs, i.e. no untreated hypertension), the prevalence of controlled hypertension increased to 59%. Masked hypertension was detected in 8.3% and white-coat hypertension in 10%. Ambulatory blood pressure correlated neither with kidney length nor with glomerular filtration rate. Echocardiography demonstrated left ventricular hypertrophy (LVH) in 27% of children at the time of their first ABPM. CONCLUSION: The prevalence of ambulatory hypertension is very high in children with ARPKD, while the control of hypertension improves over time.

Intrahepatic bile ductal ectasia in autosomal recessive polycystic kidney disease evaluated by fetal magnetic resonance imaging: a more frequent complication.

OBJECTIVE: This study aimed to evaluate liver malformations and intrahepatic bile ductal ectasia and dilatation (IBDED) in cases of prenatal diagnosis of autosomal recessive polycystic kidney disease (ARPKD) using magnetic resonance imaging (MRI). METHODS: This retrospective study involved 209 cases referred for fetal MRI studies (f-MRI) from March 2004 and December 2019, suspicious of congenital renal disease. Fetuses that met the criteria for ARPKD were selected. RESULTS: Six cases were diagnosed as ARPKD (2.8%). The median gestational age at MRI examination was 28 weeks (24-36 weeks). IBDED was observed in 84% of cases. Moreover, 66% presented multilobar liver lesions, and 33% exhibited monolobar lesions. The "central dot sign" (CDS) was found in half of the cases. CONCLUSION: In this case series of prenatal diagnosis of ARPKD using f-MRI, IBDED was present in the majority of the cases, and the CDS was noted in half of the cases.

Imaging manifestations of Caroli disease with autosomal recessive polycystic kidney disease: a case report and literature review.

BACKGROUND: Both Caroli disease (CD) and autosomal recessive polycystic kidney disease (ARPKD) are autosomal recessive disorders, which are more commonly found in infants and children, for whom surviving to adulthood is rare. Early diagnosis and intervention can improve the survival rate to some extent. This study adopted the case of a 26-year-old pregnant woman to explore the clinical and imaging manifestations and progress of CD concomitant with ARPKD to enable a better understanding of the disease. CASE PRESENTATION: A 26-year-old pregnant woman was admitted to our hospital for more than 2 months following the discovery of pancytopenia and increased creatinine. Ultrasonography detected an enlarged left liver lobe, widened hepatic portal vein, splenomegaly, and dilated splenic vein. In addition, both kidneys were obviously enlarged and sonolucent areas of varying sizes were visible, but color Doppler flow imaging revealed no abnormal blood flow signals. The gestational age was approximately 25 weeks, which was consistent with the actual fetal age. Polyhydramnios was detected but no other abnormalities were identified. Magnetic resonance imaging revealed that the liver was plump, and polycystic liver disease was observed near the top of the diaphragm. The T1 and T2 weighted images were the low and high signals, respectively. The bile duct was slightly dilated; the portal vein was widened; and the spleen volume was enlarged. Moreover, the volume of both kidneys had increased to an abnormal shape, with multiple, long, roundish T1 and T2 abnormal signals being observed. Magnetic resonance cholangiopancreatography revealed that intrahepatic cystic lesions were connected with intrahepatic bile ducts. The patient underwent a genetic testing, the result showed she carried two heterozygous mutations in PKHD1. The patient was finally diagnosed with CD with concomitant ARPKD. The baby underwent a genetic test three months after birth, the result showed that the patient carried one heterozygous mutations in PKHD1, which indicated the baby was a PKHD1 carrier. CONCLUSIONS: This case demonstrates that imaging examinations are of great significance for the diagnosis and evaluation of CD with concomitant ARPKD.

Bladder Agenesis and Bilateral Ectopic Ureters in an Infant Male With Cystic Renal Dysplasia, Imperforate Anus, and Penoscrotal Transposition.

Bladder agenesis is a rare congenital anomaly infrequently reported in the literature, with an incidence of 1/600,000 patients.1 Commonly associated with other fatal malformations, the condition is often incompatible with life.2 Prior reports estimate that over 90% of living children born with this malformation are female, owing to renal preservation resulting from low pressure drainage of urine into the vagina, uterus, and vestibule.3,4 Herein we report a rare case of an infant male born with penoscrotal transposition and end stage renal disease secondary to bilateral cystic renal dysplasia found to have concurrent bladder agenesis and bilateral ureteral ectopia.

Long-term kidney and liver outcome in 50 children with autosomal recessive polycystic kidney disease.

BACKGROUND: Autosomal recessive polycystic kidney disease (ARPKD) is a rare ciliopathy characterized by congenital hepatic fibrosis and cystic kidney disease. Lack of data about long-term follow-up makes it difficult to discuss timing and type of organ transplantation. Our objectives were to evaluate long-term evolution and indications for transplantation, from birth to adulthood. METHODS: Neonatal survivors and patients diagnosed in postnatal period with ARPKD between 1985 January and 2017 December from 3 French pediatric centers were retrospectively enrolled in the study. RESULTS: Fifty patients with mean follow-up 12.5 ± 1 years were enrolled. ARPKD was diagnosed before birth in 24%, and at mean age 1.8 years in others. Thirty-three patients were < 1 year of age at first symptoms, which were mostly kidney-related. These most often presented high blood pressure during follow-up. Portal hypertension was diagnosed in 29 patients (58%), 4 of them with bleeding from esophageal varices. Eight patients presented cholangitis (> 3 episodes in three children). Liver function was normal in all patients. Nine children received a kidney transplant without liver complications. A 20-year-old patient received a combined liver-kidney transplant (CLKT) for recurrent cholangitis, and a 15-year-old boy an isolated liver transplant for uncontrollable variceal bleeding despite portosystemic shunt. CONCLUSIONS: Long-term outcome in patients with ARPKD is heterogeneous, and in this cohort did not depend on age at diagnosis except for blood pressure. Few patients required liver transplantation. Indications for liver or combined liver-kidney transplantation were limited to recurrent cholangitis or uncontrollable portal hypertension. Liver complications after kidney transplantation were not significant.

Early nephrectomy in neonates with symptomatic autosomal recessive polycystic kidney disease.

INTRODUCTION: Autosomal recessive polycystic kidney disease (ARPKD) is a rare cause of renal failure with a highly variable clinical course. Patients who are symptomatic early in life frequently require early nephrectomy and peritoneal dialysis. In these patients there are little data to guide clinicians on whether to select unilateral nephrectomy or bilateral nephrectomy at the initial operative intervention. We review our experience with this disease process. METHODS: A retrospective review was performed of 11 patients at our institution with ARPKD symptomatic within the first month of life. Charts were reviewed for relevant clinical data, and patients were divided into groups based on undergoing either unilateral or bilateral nephrectomy at their initial intervention. The decision for unilateral versus bilateral nephrectomy was decided by the clinical team without any available guidelines. RESULTS: Of the 11 patients reviewed, two patients died within the first two weeks from other complications. The remaining 9 all required nephrectomy, with 5 undergoing synchronous bilateral nephrectomy, and 4 undergoing initial unilateral nephrectomy. All four patients required removal of their contralateral kidney, a median of 25.5 days later. There was no difference in mortality, ventilator free days, or time to full feeds between the two groups, although the group undergoing initial unilateral nephrectomy had more TPN days than their counterparts (28 vs 17 days, p = 0.014). CONCLUSIONS: In our cohort, there were few significant differences between the groups based on choice of initial unilateral or bilateral nephrectomy, and all children ultimately required removal of both kidneys. These data suggest that anesthetic exposures and other clinical outcomes might be optimized by initial bilateral nephrectomy. LEVEL OF EVIDENCE: III.

Type IV choledochal cyst with polycystic kidney disease: a case report.

BACKGROUND: Choledochal cysts are divided into 5 types. Physicians believe that Caroli disease (which refers to type V biliary cysts) is a special type of biliary cyst caused by a mutation in the PKHD1 gene and is associated with autosomal recessive polycystic kidney disease (ARPKD). There is currently no clear association between other types of choledochal cysts and polycystic kidney disease. CASE PRESENTATION: We report a 65-year-old male patient with jaundice, decreased appetite, and itchy skin. His biochemistry test results indicated obstructive jaundice disease. Cross-sectional imaging showed a type IVA choledochal cyst accompanied by autosomal dominant polycystic kidney disease (ADPKD). Due to economic difficulties, the patient achieved percutaneous transhepatic cholangial drainage (PTCD) instead of surgery. CONCLUSION: To our knowledge, this is the second case report of the coexistence of type IVA choledochal cysts and ADPKD. We conclude that it is vital to be aware that the above condition is a possibility. This case report will aid earlier diagnosis and management and possibly prevent further damage to liver and kidney function.

Prospective evaluation of kidney and liver disease in autosomal recessive polycystic kidney disease-congenital hepatic fibrosis.

BACKGROUND AND OBJECTIVES: We have previously published the characteristics of kidney and liver disease in a cohort of 73 individuals with molecularly confirmed autosomal recessive polycystic kidney disease-congenital hepatic fibrosis, based upon cross-sectional data. Here, we present prospective data on the same cohort. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: Comprehensive biochemical and imaging data on progression of kidney and liver disease in 60 of the 73 patients were prospectively collected at the NIH Clinical Center on multiple visits between 2003 and 2019. RESULTS AND CONCLUSIONS: Of the 73 patients, 23 received a renal allograft at an average age of 17.5 years and 10 underwent liver transplantation at an average age of 20.3 years. Patients who presented perinatally and those who had corticomedullary disease required kidney transplantation significantly earlier. The mean eGFR slope in patients with corticomedullary disease was -1.6 ml/min/1.73 m2/y, in comparison to -0.6 ml/min/1.73 m2/y in those with medullary disease. Kidney size remained the same over time and normalized to the upper limit of normal by 20-25 years of age. The extent of renal disease on ultrasound remained largely unchanged; no patient progressed from the "medullary" to the "corticomedullary" group. There was no correlation between eGFR slope and kidney size. The synthetic function of the liver remained largely intact even in patients with advanced portal hypertension. Based on spleen length/height ratio, two thirds of patients had portal hypertension which remained stable in 39% and worsened in 61%. Patients with portal hypertension had lower platelet counts and relatively higher levels of AST, GGT, direct bilirubin and ammonia. The progression rates of kidney and liver disease were independent of each other. Patients with bi-allelic non-truncating PKHD1 variants had similar progression of kidney and liver disease in comparison to those who were compound heterozygous for a non-truncating and a truncating variant.

Individualized concept for the treatment of autosomal recessive polycystic kidney disease with end-stage renal disease.

Management of children with autosomal recessive polycystic kidney disease (ARPKD) who develop end-stage renal disease (ESRD) remains challenging because of concomitant liver disease. Patients with recurrent cholangitis are candidates for liver-kidney transplantation, while the treatment for patients with splenomegaly and pancytopenia due to portal hypertension is controversial. Herein, we report 7 children who were treated using an individualized treatment strategy stratified by liver disease. Two patients with recurrent cholangitis underwent sequential liver-kidney transplantation, while 4 patients with splenomegaly and pancytopenia but without recurrent cholangitis underwent splenectomy followed by isolated kidney transplantation. The remaining patient, who did not have cholangitis and pancytopenia, underwent isolated kidney transplantation. Blood cell counts were normalized after splenectomy was performed at the median age of 8.7 (range, 7.4-11.7) years. Kidney transplantation was performed at the median age of 8.8 (range, 1.9-14.7) years in all patients. Overwhelming post-splenectomy infections and cholangitis did not occur during the median follow-up period of 6.3 (range, 1.0-13.2) years. The estimated glomerular filtration rate at the last follow-up was 53 (range, 35-107) mL/min/1.73 m2 . No graft loss occurred. Our individualized treatment strategy stratified by recurrent cholangitis and pancytopenia can be a feasible strategy for children with ARPKD who develop ESRD and warrants further evaluation.

A rare case of hemodialysis-related portosystemic encephalopathy and review of the literature.

Hemodialysis-related portosystemic encephalopathy (HRPSE) is a clinical phenomenon where portosystemic encephalopathy (PSE) develops without liver dysfunction, usually caused by changes in the portosystemic blood flow related to hemodialysis. We describe the case of a 22-year old patient with a transjugular intrahepatic portosystemic shunt (TIPS) who developed HRPSE several months after initiation of hemodialysis. Despite initial therapy with laxatives and neomycin symptoms recurred. It was only after relocation of the hemodialysis catheter from the superior caval vein to the femoral vein that symptoms completely resolved.

Ruptured intracranial aneurysm and recessive polycystic kidney Disease: A Rare Association.

Autosomal recessive polycystic kidney disease (ARPKD) is the most common childhood-onset ciliopathy. Intracranial aneurysms (ICA) are a serious complication of autosomal dominant polycystic kidney disease (ADPKD). However, there are only three reports about ICA in an adult patient with ARPKD. We describe a rare case of a 29-year-old man with ARPKD presenting with subarachnoid hemorrhage secondary to a ruptured intracranial aneurysm. The diagnosis of ARPKD was at the age of eight years based on typical ultrasonography findings with polycystic kidneys and liver disease. Magnetic resonance cholangiography showed a nonobstructive dilatation of intrahepatic bile ducts. Liver biopsy showed hepatic fibrosis. None of the family members was affected. At the age of 15 years, he had progressed to end-stage kidney disease, and hemodialysis was started. The patient had always a severe arterial hypertension. At the age of 29 years, he complained of headaches with an uncontrolled hypertension and disturbance of consciousness, computed tomography angiography showed subarachnoid hemorrhage and multiple cerebral aneurysms. Early neurologic screening of intracranial aneurysm should be recommended in ARPKD like in ADPKD patients.

A teenage patient with autosomal recessive polycystic kidney disease, a splenorenal shunt, and congenital hepatic fibrosis: a case report / Doença renal policística autossômica recessiva, shunt esplenorrenal e fibrose hepática congênita em adolescente: relato de caso

ABSTRACT A 16-year-old female patient previously diagnosed with autosomal recessive polycystic kidney disease (ARPKD) presented with acute bilateral pneumonia, upper gastrointestinal bleeding caused by ruptured esophageal varices, ascites, and lower limb edema. She required intensive care and an endoscopic procedure to treat the gastrointestinal bleeding. The analysis of the differential diagnosis for chronic liver disease indicated she had a spontaneous splenorenal shunt. Ultrasound-guided biopsy revealed the patient had cirrhosis, as characteristically seen in individuals with ARPKD. She had no symptoms at discharge and was referred for review for a combined transplant.

RESUMO Relato de caso de uma paciente adolescente de 16 anos de idade com diagnóstico prévio de doença renal policística autossômica recessiva (DRPAR), que apresentou quadro agudo de pneumonia bilateral e hemorragia digestiva alta por ruptura de varizes esofágicas, bem como ascite e edema de membros inferiores. Necessitou de estabilização clínica intensiva e tratamento endoscópico do sangramento digestivo. Após investigação dos diagnósticos diferenciais da hepatopatia crônica, diagnosticou-se shunt esplenorrenal espontâneo, e realizou-se biópsia hepática guiada por ecografia com diagnóstico de cirrose, espectro típico da DRPAR. Recebeu alta hospitalar assintomática e foi encaminhada para avaliação de transplante duplo.

Clinical courses and complications of young adults with Autosomal Recessive Polycystic Kidney Disease (ARPKD).

Autosomal recessive polycystic kidney disease (ARPKD) is a severe pediatric hepatorenal disorder with pronounced phenotypic variability. A substantial number of patients with early diagnosis reaches adulthood and some patients are not diagnosed until adulthood. Yet, clinical knowledge about adult ARPKD patients is scarce. Here, we describe forty-nine patients with longitudinal follow-up into young adulthood that were identified in the international ARPKD cohort study ARegPKD. Forty-five patients were evaluated in a cross-sectional analysis at a mean age of 21.4 (±3.3) years describing hepatorenal findings. Renal function of native kidneys was within CKD stages 1 to 3 in more than 50% of the patients. Symptoms of hepatic involvement were frequently detected. Fourteen (31%) patients had undergone kidney transplantation and six patients (13%) had undergone liver transplantation or combined liver and kidney transplantation prior to the visit revealing a wide variability of clinical courses. Hepatorenal involvement and preceding complications in other organs were also evaluated in a time-to-event analysis. In summary, we characterize the broad clinical spectrum of young adult ARPKD patients. Importantly, many patients have a stable renal and hepatic situation in young adulthood. ARPKD should also be considered as a differential diagnosis in young adults with fibrocystic hepatorenal disease.

Simultaneous laparoscopic left lateral sectionectomy and nephrectomy in the same living donor: The first case report.

With the presence of organ shortage, living donors remain important sources of grafts, especially for pediatric recipients. Laparoscopic nephrectomy has become the gold standard for living donors. Additionally, laparoscopic partial liver procurement in living donors has proven its safety and feasibility in the latest studies. We have combined both approaches to perform a simultaneous liver-kidney transplantation in a pediatric patient from the same living donor. Our experience of laparoscopic left lateral sectionectomy and laparoscopic nephrectomy in living donors was the basis for adapting to this procedure. A 29-year-old mother was an ABO-incompatible (ABOi) donor for the left lateral section (LLS) of the liver and left kidney for her 2-year-old son. The postoperative period was uneventful. Two sessions of plasmapheresis and rituximab induction were necessary to prepare for ABOi transplantation. The donor and recipient were discharged on postoperative days 5 and 28, respectively. Simultaneous laparoscopic left lateral sectionectomy and nephrectomy in the same living donor is feasible for transplantation from the parent to the child with advanced laparoscopic expertise.
