In the beginning, the kidney opening and closure technique is (24). We had applied repair with fatty tissue in 79 patients and fatty tissue-free repair in 64 patients.…”

After nephron-sparing surgery (NSS), postsurgical fatty tumor could be mistakenly reported as angiomyolipoma during radiologic imaging of some patients. In the present paper, we studied the postsurgical fatty tumor detected after NSS but not covered before in the literature. In addi-tion, we also evaluated whether the postsurgical fatty tumor was related to the surgical technique employed. Patients admitted to the urology department of our university hospital from 2014 to 2019 and operated with open NSS were evaluated retrospectively. We detected those 156 patients were operated with NSS. Nine patients with angiomyolipoma as primary pathology and four patients with surgical border positivity were excluded from the study. The patients were divided into two groups based on the repair of tumor extraction region. In Group 1, fatty tissue was used for repair, and Group 2 is the primary repair group. In all, 143 patients (Group 1 = 79, and Group 2 = 64) were included in the study. No demographic and radiologic differences, such as number of patients, age, gender, positioning of tumor, mass localization, tumor diameter, and RENAL nephrometry scoring system, were detected between the two groups. Postsurgical fatty tumors were detected in 28 patients in Group 1 and in two patients in Group 2 (P < 0.001). In patients with negative surgical margins after partial nephrectomy, lesions that were radiologically detected mimicking as angiomyolipoma were defined as “postsurgical fatty tumor.” This mass containing adipose tissue only nei-ther depicted vascularization and enhancement nor increase in size for at least 1 year. We assumed that these lesions must be followed as benign lesions not requiring additional treatment.

“…Use of fatty tissue prevents urinary leakage, provides successful hemostasis, and a tension-free repair. Özkan et al called this technique “lipocorticoplasty” in a study published in 2011 ( 24 ). We had applied repair with fatty tissue in 79 patients and fatty tissue-free repair in 64 patients.…”

“…Some technical innovations have been attempted to prevent tearing of the suture through renal parenchyma and then to decrease complication rate of partial nephrectomy. 19,24,26 In recent years, different kinds of in vitro tissue loading system and force measurement device have been developed to investigate soft tissue properties. Snedeker et al 23 built up a force/displacement amplification apparatus to characterize the mechanical properties of the kidney capsular membrane.…”

Further understanding of the mechanical deformation and tear behavior of kidney during suturing helps to enhance surgical task execution that requires fine suture manipulation. This paper aims to develop a model to describe the relationship between the tensile force acting on suture line and the resulted kidney deformation in the tension of suture line. The tensile force was recorded during multiple suture procedures, filtered, and we extracted the force data between the beginnings of tensioning suture line and tearing renal remnant. The extracted data were interpolated to obtain the same data sample length for each suture procedure, and then used to train the back propagation (BP) neural network. In order to predict the tearing force, force data were collected in sequence and interpolated to be input into BP network. Suture processes were performed on in vitro porcine kidneys, and experimental results verified the effectiveness of predictive modeling and the accuracy of tearing force prediction. The relative error for tearing force prediction was about 15%. The predictive modeling method can be used to forecast the tearing force before the suture line tears through soft tissues.

Objective: To evaluate the impact of Double J stent (DJS) insertion during open partial nephrectomy (OPN) on postoperative prolonged urinary leakage. Materials and methods: A retrospective study was made in consecutive cases of OPN performed between 2002 and 2020 for localized kidney tumors at our tertiary center. Urinary leakage was defined as drainage > 72 hours after surgery by biochemical analysis consistent with urine or radiographic evidence of urine leakage. The patients were divided into two groups according to intraoperative DJS placement, and compared regarding clinicopathologic characteristics, perioperative and postoperative outcomes. Univariate and multivariate logistic regression analyses were performed to determine the factors associated with urinary leakage after the operation. Results: Review of records identified 182 patients who were included in the study. In 73 (40%) patients PN was performed without insertion of a DJS. Thus, 109 (60%) of patients had a DJS inserted. Apart from higher preoperative eGFR values among patients with DJS (96.6 vs. 94.3 mL/min/1.73 m²; p = 0.03), demographic characteristics were similar between groups. The two groups were not different regarding perioperative, postoperative and clinicopathologic outcomes. Patients with DJS had longer ischemia times (31 vs. 23 min; p = 0.02) and longer length of stay (6 vs. 5 days; p = 0.04). Urinary leakage was seen in 7.6% (n = 14) of all patients and it did not differ according to DJS placement (DJS+ 9.2 vs. DJS- 5.5%; p = 0.41). On multivariate analysis, the tumor nearness to the collecting system was the sole independently significant factor (p = 0.04) predicting postoperative urine leak. Conclusions: Routine intraoperative DJS insertion during OPN does not appear to reduce the probability of postoperative urine leak.
