“…Traditional printing technology can not meet the huge workload, and can not adapt to the update frequency of packaging style. 7 And digital printing technology, using digital layout, no plate making time, can greatly save time, save production costs. And digital printing can ensure the quality of the label, avoid the printing effect is not good, resulting in effective information is difficult to convey or affect the corporate image.…”

“…Furthermore, the continence function in both the day- and nighttime must be achieved [ 14 ]. The standard technique involves the creation of the Studer neobladder; however, other ileo-colonic neobladder techniques have also been used, such as the Karolinska-modified Studer neobladder, the University of Southern California-modified Studer neobladder, the N pouch, the W pouch, the modified Y-shaped, and other orthotopic neobladders for which the long-term outcomes are comparable in oncological and functional outcomes to standard Studer technique or ileal conduit [ 7 , 15 – 18 ]. Although the Studer technique has significant advantages over the other alternatives.…”

Background To explore a method of constructing an orthotopic ileal neobladder (ONB) in the Y-pouch configuration. We describe the steps followed to create the Y-pouch ileal orthotopic neobladder (ONB) and compared the perioperative, functional, and urodynamics outcomes with the Studer neobladder technique. Methods A retrospective cohort study of 90 bladder cancer patients, who received open radical cystectomy with the ONB performed at a hospital from June 2009 to May 2020. These patients were divided into two groups—the Y-pouch and the Studer neobladder groups. Perioperative, functional outcome, complication, renal function data outcomes, and pressure–volume study were used to evaluate the treatment outcomes after a radical cystectomy. Results Ninety patients (54 Studer and 36 Y-pouch neobladder) were enrolled. The median patient age was 62.6 (± 11) years. The mean operative time for the Studer technique was 290 (242.5–350) min, and the Y-pouch technique was 300 (271.2–335) min) (p = 0.826). At 30 days postoperatively, the Clavien-Dindo classification of surgical complications revealed grade-2 urinary infections in two patients (5.6%) and six patients (11.1%) for the Y-pouch and Studer techniques, respectively. Intermediate complications (30–90 days) were reported in 4 (11.1%) and 18 patients (44.4%) in the Y-pouch and the Studer techniques, respectively (p = 0.062). In the urodynamics study (UDS), the Y-pouch group had a mean postvoid residual volume of 20 mL and Studer of 40 ml (p = 0.06). A mean capacity of 462 (380–600) mL compares to the Studer neobladder group with 495 (400–628) mL. The average mean compliance of the Studer group was 35.5 (28–52) ml/cm H2O and 33 (30–43) ml/cm H2O for Y pouch, and most patients had > 30 ml/cm H2O compliance (80/90 patients). Conclusions The Y-pouch neobladder technique in an RC with an orthotopic neobladder provides perioperative and functional outcomes compared to those of the Studer orthotopic neobladder resulting in similar intermediate-term. Therefore, the Y-pouch ileal neobladder is both feasible and safe to be used as a standard neobladder technique for urinary diversion in patients with bladder cancer undergoing radical cystectomy and needs confirmation with long-term results.

Bladder cancer represents the most common malignancy of the urinary system, posing a significant threat to patients' life. Animal models and two-dimensional (2D) cell cultures, among other traditional models, have been used for years to study various aspects of bladder cancer. However, these methods are subject to various limitations when mimicking the tumor microenvironment in vivo, thus hindering the further improvement of bladder cancer treatments. Recently, three-dimensional (3D) culture models have attracted extensive attention since they overcome the shortcomings of their traditional counterparts. Most importantly, 3D culture models more accurately reproduce the tumor microenvironment in the human body because they can recapitulate the cell-cell and cell-extracellular matrix interactions. 3D culture models can thereby help us gain deeper insight into the bladder cancer. The 3D culture models of tumor cells can extend the culture duration and allow for co-culturing with different cell types. Study of patient-specific bladder cancer mutations and subtypes is made possible by the ability to preserve cells isolated from particular patients in 3D culture models. It will be feasible to develop customized treatments that target relevant signaling pathways or biomarkers. This article reviews the development, application, advantages, and limitations of traditional modeling systems and 3D culture models used in the study of bladder cancer and discusses the potential application of 3D culture models.
