“…Duplex kidney is the most common congenital anomaly of the urinary system, with a prevalence of approximately 0.8-1% in the general population, often detected incidentally due to the lack of symptoms [5,6,11]. Although RCC is the most common kidney cancer, RCC in duplex kidneys is an exceedingly rare condition [4,6].…”

Background The duplex kidney is one of the common congenital anomalies of the kidney and urinary tract. We present two cases of renal tumor accompanied with ipsilateral duplex kidney. The image of the tumor, renal artery system and collecting system were rendered by AI software (Fujifilm’s Synapse® AI Platform) to support the diagnosis and surgical planning. Case presentation Two Vietnamese patients (a 45-year-old man and a 54-year-old woman) with incidental cT1 renal cell carcinoma (RCC) were confirmed to have ipsilateral duplex kidneys by 3D reconstruction AI technique. One patient had a Renal score 9ah tumor of left kidney while the other had a Renal score 9 × tumor of right kidney in which a preoperative CT scan failed to identify a diagnosis of duplex kidney. Using the Da Vinci platform, we successfully performed robotic partial nephrectomy without any damage to the collecting system in both cases. Conclusion RCC with duplex kidneys is a rare condition. By utilizing a novel AI reconstruction technique with adequate information, two patients with RCC in duplex kidneys were successfully performed robotic partial nephrectomy without complication.

“…The majority of patients with duplicated kidneys are asymptomatic, often discovered incidentally during prenatal examinations or postnatal check-ups. Some patients may experience recurrent urinary tract infections, dribbling outside of the voiding period, difficulty in urination caused by ureteral cysts, abdominal pain, progressive decline in renal function, and worsening of hydronephrosis ( 2 - 4 ). The management options for completely duplicated kidney anomalies with surgical indications include anomalous single ureter reimplantation, double ureteral sheath reimplantation, distal ureteral cystostomy, upper and lower pole ureteroureterostomy (UU), and upper pole nephrectomy ( 5 ).…”

Background Duplicated kidneys, though rare, are common in pediatric urinary issues. For children with complete kidney duplication and symptoms or complications, surgery is often needed. Ureteroureterostomy (UU) is a common procedure for this condition. This study aims to evaluate and compare the clinical efficacy and safety of laparoscopic ureteroureterostomy (LUU) and open ureteroureterostomy (OUU) in the treatment of pediatric duplicated kidneys. Methods A retrospective study at Children’s Hospital of Anhui Province from February 2017 to January 2023 included pediatric patients who underwent LUU or OUU for completely duplicated kidneys. Comparative measures included operative time, postoperative hospital stay, intraoperative blood loss, pre- and postoperative renal pelvis anteroposterior diameter, pre- and postoperative upper renal parenchymal thickness, pre- and postoperative upper ureteral diameter, and postoperative complications. Results There are 30 patients, 20 in the LUU group and 10 in the OUU group. All patients underwent surgery successfully, with no conversions to open surgery in the LUU group. Comparison between the LUU group (average age 3.7±3.4 years) and the OUU group (average age 1.6±1.3 years) showed that laparoscopic surgery had a mean duration of 178.8±60.71 min, intraoperative blood loss of 4.3±0.92 mL, drainage tube removal time of 1.8±0.6 days, and postoperative hospital stay of 4.2±2.2 days. In contrast, the OUU group had a mean surgery duration of 181.6±37.8 min, drainage tube removal time of 2.3±0.7 days, intraoperative blood loss of 6.4±4.06 mL, and postoperative hospital stay of 5.8±1.8 days. Although the LUU group had a shorter surgical duration, the difference was not statistically significant. However, intraoperative blood loss, drainage tube removal time, and postoperative hospital stay were significantly reduced in the LUU group, with statistical significance (P<0.05). After surgery, one case of urinary tract infection occurred in each group. Both groups had double-J stents placed postoperatively, which were removed cystoscopically 4–6 weeks later. Preoperative examinations showed no significant differences between the LUU and OUU groups in terms of upper renal pelvis anteroposterior diameter, upper renal ureteral diameter, and upper renal parenchymal thickness. However, in terms of postoperative recovery indicators, the LUU group outperformed the OUU group significantly, including upper renal pelvis anteroposterior diameter, upper renal ureteral diameter, and upper renal parenchymal thickness, with statistical significance (P<0.05). No hydronephrosis or worsening hydronephrosis was observed in the lower kidneys and ureters of the 30 patients postoperatively. Symptoms disappeared in patients with preoperative dribbling, and pain symptoms in the waist and abdomen relieved. No postoperative febrile urinary tract infections were observed. Conclusions UU is an effective and safe m...

“…The exact causes and mechanisms of kidney abnormalities have yet to be fully understood [3], but research in recent years has identified a variety of genetic, environmental, and lifestyle factors that may contribute to their development [4]. The severe symptoms of kidney abnormalities include a pain in the side or back; blood in the urine; fatigue; and swelling in the legs and feet [5]. The most common kidney abnormalities that impair kidney function are the development of cysts, nephrolithiasis (kidney stones), and renal cell carcinoma (kidney tumor) [6].…”

Exploring the Capabilities of a Lightweight CNN Model in Accurately Identifying Renal Abnormalities: Cysts, Stones, and Tumors, Using LIME and SHAP

Kidney abnormality is one of the major concerns in modern society, and it affects millions of people around the world. To diagnose different abnormalities in human kidneys, a narrow-beam x-ray imaging procedure, computed tomography, is used, which creates cross-sectional slices of the kidneys. Several deep-learning models have been successfully applied to computer tomography images for classification and segmentation purposes. However, it has been difficult for clinicians to interpret the model’s specific decisions and, thus, creating a “black box” system. Additionally, it has been difficult to integrate complex deep-learning models for internet-of-medical-things devices due to demanding training parameters and memory-resource cost. To overcome these issues, this study proposed (1) a lightweight customized convolutional neural network to detect kidney cysts, stones, and tumors and (2) understandable AI Shapely values based on the Shapley additive explanation and predictive results based on the local interpretable model-agnostic explanations to illustrate the deep-learning model. The proposed CNN model performed better than other state-of-the-art methods and obtained an accuracy of 99.52 ± 0.84% for K = 10-fold of stratified sampling. With improved results and better interpretive power, the proposed work provides clinicians with conclusive and understandable results.
