Minimally invasive open nephrectomy on children with multicystic dysplastic kidney

Abstract

The aim of the study was to summarize the preliminary experience of minimally invasive open nephrectomy operation on children with multicystic dysplastic kidney (MCDK). A retrospective review was performed on the clinical materials of the 15 children that had accepted consecutive minimally invasive open nephrectomies during the previous 2 years. The enrolled children were diagnosed with unilateral MCDK under computed tomography, emission computerized tomography and ultrasound and no anomaly in the contralateral functioning kidney was found. Of the 15 children, 12 were boys and 3 were girls, with 5 cases on the right and 10 cases on the left. Operations were completed at the retroperitoneal space in order to open an incision on the waists and ribs of the children, the length of which ranged from 1.5 to 2.0 cm (average 1.7 cm). The age of the children at operation ranged from 3 months to 5.6 years old, with an average of 2.4 years old. Surgery lasted for 30–50 min, with an average of 34.6 min. The estimated blood loss of each child was <5 ml. After operation, prophylactic intravenous antibiotics were administered for 2–4 days to prevent infection. All of the operations proved very successful. Following surgery the children were hospitalized for 2–4 days for observation, with an average of 2.8 days. No complications occurred during the follow-up period. In conclusion, minimally invasive open nephrectomy is effective for children with MCDK. The procedure is superior with regard to operative time, cosmesis, and length of stay. It is a safe and effective treatment choice for patietns with MCDK and can be easily performed on children.

“Watch and Wait” Strategy for Multicystic Dysplastic Kidney (MCDK): Status Survey of Perceptions, Attitudes, and Treatment Selection in Chinese Pediatric Urologists and Pediatric Surgeons

“…However, debate and problems have been continuing in the implementation process in China. Some Chinese scholars support surgical resection of the affected kidney because of concerns regarding the potential risks, such as malignancy and hypertension (12). In this report, we designed a survey to gather information about the opinions and practice patterns of pediatric urologists and pediatric surgeons from different parts of China regarding this question.…”

“…A "watch and wait" strategy is advocated according to recent natural history studies of MCDK (2). However, in some institutions, routine early surgical removal of these kidneys was advocated previously because of concerns about the potential for hypertension and malignancy (11,12). The appropriate management strategy for this anomaly is debated, and strategies are inconsistent within and between institutions.…”
