ABSTRACT

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease and one of the most common causes for end-stage renal disease (ESRD). Kidney transplantation is the optimal renal replacement therapy for ADPKD patients complicated with ESRD. Currently, scholars at home and abroad have a certain controversy about whether polycystic kidney resection is necessary in ADPKD patients before kidney transplantation, and the criteria and methods for polycystic nephrectomy also differ. To further standardize the clinical technical operation of kidney transplantation in ADPKD patients, experts in organ transplantation organized by Branch of Organ Transplantation of Chinese Medical Association formulated this specification from the aspects of diagnosis of ADPKD, indications and contraindications of kidney transplantation for ADPKD, preoperative evaluation and treatment, polycystic nephrectomy, and postoperative management, etc.

ABSTRACT

Laparoscopic decortication is the standardized surgical treatment for simple renal cysts. With the continuous maturation of minimally invasive techniques, percutaneous nephroscopic decortication and decompression is gradually implemented, which has advantages of minimal invasiveness, fast recovery and good prognosis. Ureteroscopic plasma electrode is a modified procedure, which can achieve more exact intraoperative hemostasis and efficient cutting efficiency than traditional surgery. This article reviews the current treatments of simple renal cysts, and introduces our experience of using minimally invasive percutaneous nephroscopic plasma electrode decortication, its surgical procedures and technical points.

ABSTRACT

Objective:To explore the application value of dual contrast-enhanced ultrasound in the differential diagnosis of renal cystic lesions.Methods:Eighty-four cases with renal cysts who were diagnosed by routine ultrasound in Zhejiang Cancer Hospital and Zhejiang Xiaoshan Hospital from January 2019 to October 2020 were included in the study. Intravenous contrast-enhanced ultrasound and enhanced MRI were performed to differentiate benign and malignant cysts. Patients with benign cysts underuent intravenous pyelography and intracapsular contrast-enhanced ultrasound. Before sclerotheraphy to exclude renal pelvic cysts. The diagnostic results of dual radiography were compared with MRI and intravenous pyelography.Results:Among 84 patients with suspected renal cysts, the diagnostic accuracy of enhanced MRI for cystic renal cancer was 97.62%, and the sensitivity was 97.62%. The diagnostic accuracy of intravenous contrast-enhanced ultrasound was 98.81, the sensitivity was 100%, and the specificity was 98.73%. There was no statistically significant difference between the two groups (all P>0.05). 77 cases were diagnosed as benign renal cysts, the detection rate of intravenous pyelography was 9.1% (7/77), the detection rate of renal pelvic cysts by intracystic ultrasonography was 6.5% (5/77). With intravenous pyelography as the gold standard, the diagnostic accuracy of intracapsular contrast-enhanced ultrasound was 97.4% (75/77), the sensitivity was 71.4% (5/7), and the specificity was 100% (70/70). Conclusions:Compared with enhanced magnetic resonance and intravenous pyelography before renal cyst sclerosing therapy, there is no difference in diagnostic efficiency of double contrast ultrasound for benign and malignant cysts. The diagnostic efficiency of renal pelvic cysts is high, and the operation is convenient. It can identify cystic renal cancer and cysts from the renal pelvis and improve the safety of sclerotherapy.

ABSTRACT

Objective:To investigate the clinical characteristics, differential diagnosis and treatment of IgG4-related kidney disease (IgG4-RKD) presenting as a cystic renal mass.Methods:A 42-year-old male patient was found having a tumor in the left kidney in an annual physical examination. Subsequent CTU scan revealed a round shadow in the lower pole of the left kidney, with slightly lower, uneven density and obscure boundaries, which was slightly enhanced on contrast-enhanced CT imaging, suggesting a cystic mass (Bosniak category Ⅲ). Contrast-enhanced MRI showed a long T1, long T2 signal lesion in the lower pole of the left kidney, which was not obviously enhanced in the cortical phase but exhibited continuous and separated enhancement in parenchymal and delayed phases, suggesting a cystic renal cell carcinoma. A preoperative diagnosis of a left renal mass was made, for which the patient underwent a laparoscopic partial nephrectomy.Results:The resected cystic mass was grey white with obscured boundaries. Microscopically, the mass showed lymphoplasmacytic hyperplasia with lymphoid follicles, cystic formation, fibrosis hyperplasia and vascular obstruction. Immunohistochemistry revealed that the number of IgG4 (+ ) plasma cells was more than 50/HPF, and over 40% IgG (+ ) plasma cells were IgG4 (+ ). By virtue of the radiologic and pathologic findings, the patient was diagnosed with IgG4-RKD. At 2 weeks after operation, serum IgG level was 0.71g/L (reference: 0.03-2.01 g/L). Chest and abdominal CT scans performed 3 months after operation showed no evidence of other organ involvement and serum IgG4 level was within the normal range. Therefore no adjuvant therapy was prescribed.Conclusions:It is usually difficult to differentiate IgG4-RKD presenting as a cystic renal mass by radiography alone. The presence of other organ involvement, serum IgG4 test and renal biopsy can help the diagnosis and so as to avoid unnecessary surgery.

ABSTRACT

Objective: To analyze the clinical characteristics, the typical pathological features and treatment methods of the patients with congenital hepatic fibrosis (CHF), and to improve the prognosis of the patients. Methods: The clinical data of a patient with CHF underwent liver transplantation for liver function failure were collected, and the relevant literatures were reviewed; the classification, clinical characteristics, diagnosis and treatment of CHF were analyzed. Results: The patient was a 39-year-old man and prensented with upper gastrointestinal bleeding. The results of gastroscope examination showed the severe varicose veins of the esophagus, which was marked by portal hypertension. The imaging examination after admission showed liver cirrhosis, splenomegaly and right renal cyst; the patient had mild liver function change, poor coagulation function, and liver function failure. After medical treatment, the condition was not improved, and the patient underwent allogeneic orthotopic liver transplantation. The postoperative liver pathology indicated CHF; all the laboratory indicators were normal after 1 month of transplantation. The patient recovered better 1 year after operation. Conclusion: CHF is characterized by liver fibrosis, portal hypertension and renal cystic lesions. Liver biopsy is the gold standard for its diagnosis, clinical treatment is mainly for the complications, and liver transplantation is the fundamental treatment.

ABSTRACT

Los quistes renales simples son poco frecuentes en recién nacidos, niños y adolescentes. Suelen ser únicos, y ocasionalmente múltiples. No existen evidencias de riesgo familiar. El objetivo de la presentación fue resaltar la importancia del diagnóstico precoz de malformaciones congénitas y/o defectos estructurales del feto, por ultrasonografía, en la atención primaria de salud. Presentamos las imágenes ecográficas de un caso de afectación fetal por un quiste renal simple a las 36 semanas, sin otros hallazgos ultrasonográficos. Previo asesoramiento genético y dado la avanzada edad gestacional y el buen pronòstico con que cursan estos casos además de no tener otro defecto genético asociado, la pareja decidió la continuación del embarazo. El caso fue confirmado por ecografía posnatal(AU)


Simple renal cysts are rare in newborns, children and adolescents. They tend to be unique, and occasionally multiple. There is no evidence of family risk. The objective of the presentation was to highlight the importance of early diagnosis of congenital malformations and / or structural defects of the fetus, by ultrasonography, in primary health care. We present the echography of a case of fetal involvement by a simple renal cyst at 36 weeks, with no other ultrasonography findings. The parents decided to continue the pregnancy previous genetic counseling, given the advanced gestational age and good prognosis with these cases, and considering there is no other genetic defect associated. The case was confirmed by postnatal ultrasound(AU)

ABSTRACT

Objective@#To investigate the efficacy and safety of rapamycin in children with tuberous sclerosis complex (TSC) associated renal disease.@*Methods@#A prospective self-control study was conducted. The clinical data of 92 children diagnosed with tuberous sclerosis complex associated kidney disease at the People′s Liberation Army General Hospital from January 2011 to January 2019 were collected. The long-term rapamycin treatment for all patients initiated at 1 mg/(m2·d), which was gradually adjusted to reach a blood concentration of 5-10 μg/L. The changes of the maximum diameter of renal lesions in children after rapamycin treatment were observed and analyzed with Wilcoxon test.@*Results@#Ninety-two children, including 52 males and 40 females, who met the criteria were analyzed. Sixty patients had only renal angiomyolipoma(RAML), while 24 patients had only multiple renal cysts(MRC), and 8 patients had both lesions. The age of TSC diagnosis was 16.0 (7.0, 42.0) months, and the age of initial treatment with rapamycin was 63.5 (21.0, 103.0) months. The follow-up lasted for 12.0 (4.0, 23.0) months. Sequencing of TSC1 and TSC2 genes was performed in 54 children with TSC, including 3 patients (6%) with mutations in TSC1 gene and 51 patients (94%) with mutations in TSC2 gene. The maximum RAML diameter before treatment was 7.0 (4.0, 9.0) mm. The best effect reached at 3 months of treatment, with the diameter of 4.0 (0,7.0) mm. The maximum diameters at 6 months, 1 year and 1-2 years were 5.0 (0,9.8) mm, 5.0 (1.5, 8.5) mm, 5.5 (3.0, 9.0) mm, respectively, and were significantly different from the baseline (Z=-2.404,-2.350,-2.750,P=0.016,0.019,0.006, respectively). The maximum diameter after 2-3 years, and ≥3 years were 5.0 (3.9,7.0) mm and 6.0 (1.0, 11.0) mm, without significant difference from the baseline (Z=-0.856,-0.102,P=0.393,0.919, respectively).The maximum diameters of MRC after 3 months, 6 months, 1 year,1-2 years, 2-3 years, and ≥3 years were 11.0 (5.0, 14.0) mm,3.0 (0.0,11.0) mm,5.0 (0,21.0) mm,0 (0,14.0) mm,0 (0,10.0) mm, and 0 (0,18.3) mm, respectively, but were not significantly different rom the baseline (7.0 (5.0, 15.7) mm)(Z=-0.944,-1.214,-1.035,-1.896,-1.603,-1.214,P=0.345,0.225,0.301,0.058,0.109,0.225, respectively).Twenty-nine patients (32%) had oral ulcers during the entire treatment period, and no serious adverse reactions were observed.@*Conclusions@#Rapamycin could decrease the diameter of TSC-related RAML, but could not inhibit the growth of cysts. It is well tolerated in the treatment of renal diseases associated with tuberous sclerosis complex.

ABSTRACT

Cystic kidney disease is the main disease of cystic kidney change in children. It may be caused by non_genetic fetal malformations or genetic diseases,or may be acquired rarely. Most renal cysts are usually isolated oraspart of a syndrome. However,fatal renal cystic diseases can develop from these space occupying lesions. Although renalcystic diseases are similar in presentation,they possess distinct features and variable prognosis later in life. In order to correctly diagnose this kind of disease in the early stage,it claim to accurately grasp its pathogenesis,pathology,clini_cal characteristics and radiological findings. A comprehensive analysis of common cystic kidney disease in children is carried out to help clinicians to aid in early distinction and appropriate treatment.

ABSTRACT

Cystic renal masses pose diagnostic challenge especially when they belong to Bosniak Type II and III. Septal and nodular enhancement on computed tomography (CT) is the strongest predictor of malignant process. A unilocular cyst with a calcified rim or a multilocular cystic lesion with heterogeneity on CT goes in favor of hydatid disease. We report a case in a 65-year-old female who presented with painless hematuria, was found to have a cystic mass in the right kidney. The mass turned out to be collecting duct carcinoma after histopathological examination though imaging studies were in favor of a hydatid cyst.

ABSTRACT

Renal cysts are frequently seen in the general population. Most small simple renal cysts are managed by conservative treatment. A renal cell carcinoma (RCC) presenting as a renal cyst is extremely uncommon, and collecting duct carcinoma is a rare type of RCC. This report describes a collecting duct carcinoma initially presnted as a renal cyst. The patient was a 52-year-old man who had been diagnosed with a renal cyst in the left lower pole 8 years earlier but was not regularly follow-up. He presented with left flank pain and gross hematuria. Computed tomography revealed a heterogeneous enhanced mass in the left lower pole and multiple para-aortic lymph nodes. He underwent radical nephrectomy and lymph nodes dissection which confirmed collecting duct carcinoma with sarcomatoid differentiation.

ABSTRACT

Objective To analyze the clinical value of ultrasound-guided percutaneous Lauromacrogol Injection sclerotherapy in the treatment of simple renal cyst. Methods A total of eighty patients with simple renal cyst, who were divided into 40 groups according to the random number table, were divided into two groups from February 2016 to April 2017. The traditional group used traditional open renal cyst unroofing decompression. Ultrasound guided ultrasound guided percutaneous Lauromacrogol Injection sclerotherapy was performed in the ultrasound guided group. The therapeutic effect, operation time and the rate of successful puncture were compared between two groups of simple renal cysts. It needs to compare the volume of the cyst and the quality of life before and after the intervention. Results Ultrasound guided group simple renal cyst treatment effect was higher than the traditional group (P<0.05). The operation time of the ultrasound guided group was shorter than that of the traditional group, and the success rate of the one shot puncture was higher than that of the traditional group(P<0.05). Before the intervention, the volume and quality of life of the two groups were similar. In the ultrasound guided group, the volume and quality of life in the ultrasound guided group were better than those in the traditional group(P<0.05). Conclusion Ultrasound guided percutaneous Lauromacrogol Injection sclerotherapy is of high clinical value in the treatment of simple renal cysts. The utility model can improve the success rate of one puncture, shorten the operation time, and the exact effect can speed up the regression of symptoms and reduce the volume of the cyst. Therefore, this method can improve the quality of life of patients.

ABSTRACT

Objective: To evaluate the performance of contrastenhanced ultrasound (CEUS) in the risk stratification of indeterminate renal lesions picked up incidentally on abdominal imaging, in patients with renal impairment. Methods: A retrospective study was performed of nonconsecutive patients who underwent CEUS at our tertiary care centre for indeterminate renal lesions between March 2010 and September 2014. A total of 63 patients with 74 nodules were assessed with CEUS and stratified into either benign (Bosniak I, II, IIF) or suspicious for malignancy (Bosniak III, IV or hypervascular solid lesions). Diagnostic accuracy was determined by comparing these findings to subsequent histological diagnoses, temporal change after at least 20 months follow-up or after a diagnostic computer tomography / magnetic resonance imaging study. Results: CEUS correctly identified 49/52 (94.2%) of benign lesions and 21/22 (95.5%) of malignant lesions, resulting in a sensitivity of 95.5% (95% CI 77.2-99.9%), specificity of 94.2% (95% CI 84.1-98.8%), positive predictive value (PPV) 87.5% (95% CI 67.6-97.3) and negative predictive value (NPV) 98.0% (95% CI 89.4-100%). Conclusion: CEUS has high diagnostic performance in predicting the benignity of a renal lesion in patients with renal impairment, showing sensitivity and NPV approaching 100%.
