Autoimmune Glial Fibrillary Acidic Protein Astrocytopathy: The Role of a Neurourogist From the Intensive Care Unit to Improving the Patient's Quality of Life.

Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is an autoimmune disease that involves GFAP autoantibodies in the cerebrospinal fluid (CSF) and serum. Clinical manifestations exhibit diverse symptoms affecting various brain regions and spinal cord. Diagnosis challenges persist due to the absence of standardized criteria, yet steroid therapy shows promise despite varied responses. Herein we present the case of a 30-year-old male with meningoencephalomyelitis symptoms, later diagnosed with autoimmune astrocytopathy. Treatment involved plasmapheresis, corticosteroids, and mycophenolate mofetil, with a positive outcome. Neurourological complications, including acute urinary retention, prompted catheterization, and urodynamic studies revealed detrusor overactivity. Timely intervention enabled the restoration of bladder function, underscoring the importance of specialized care in complex neurologic conditions for improving patients' quality of life (QoL). This case emphasizes the significance of early neurourological intervention and the role of specialized centers in delivering tailored care for better patient outcomes.

The Da Vinci Single-Port (SP) Treatment of Nutcracker Syndrome: A Case Report of a Novel Approach.

Nutcracker syndrome (NCS) is a rare disease affecting the left kidney. Surgical management is the only choice of treatment. Minimal invasive surgeries can be effective and may prevent complications of the major surgery. We present the case of a 33-year-old woman suffering from chronic left flank pain, diagnosed with NCS and treated with extravascular stents. Robotic-assisted extravascular stent insertion was performed using the Da Vinci single-port (SP) (Intuitive Surgical, Inc., Sunnyvale, USA) system. This approach offers the advantages of minimal invasiveness, precise stent placement, and reduced operative time. To our knowledge, this is the first case of using Da Vinci SP for this indication. Further studies are needed to evaluate the long-term outcomes and safety.

A review of robotic-assisted laparoscopic partial nephrectomy in the management of renal duplication anomalies.

Open and purely laparoscopic partial nephrectomy or heminephrectomy has been the standard management for renal duplication anomalies for symptomatic children with non-functional renal moieties. While robotic-assisted laparoscopic partial nephrectomy (RALPN) has been established as a safe and feasible option for the management of renal duplex anomalies, there remains a paucity of data on this topic. The aim of this study is to comprehensively review all available outcomes data and update the use of emerging technologies in robotic surgery which continue to make RALPN a viable and advantageous option in the management of renal duplex anomalies.

Utilizing Condoms in Laparoscopic Gynecologic Cancer Surgeries: A Profitable Safeguard?

Minimally invasive approach is a well-established strategy in the initial exploration or definitive management of the eligible gynecological cancers. It provides the benefits of improved surgical recovery to the patients. However, the last step of the specimen extraction through the smallest incision possible is always challenging for most of the surgeons. The in-bag retrieval of specimen needs utmost attention in most of the malignancies for the preservation of tumor integrity to avoid tumor seedling and upstaging of the disease. The various kinds of commercially available bags are already being utilized for the retrieval of specimens. However, the venture into innovative methods of development of novel and economical specimen retrieval system is desirable owing to the high cost of the commercial endobags. Here, we have described a very simple, safe, and cost-effective technique of specimen retrieval using the ETO sterilized condoms for smaller specimens' extraction in gynecological cancer surgeries.

Less correction with minimally invasive surgery for adolescent idiopathic scoliosis compared to open surgical correction.

Purpose: In this study, we investigated the relationship between the results of thoracic curve correction using minimally invasive surgeries in 35 patients and open surgical correction in 47 patients with adolescent idiopathic scoliosis. Methods: The correlations between the Cobb's angle of the primary and postoperative curves, angle of thoracic kyphosis and lumbar lordosis, correction percentage, derotation values, estimated blood loss, duration of surgery, and period of hospitalization after surgery were assessed by calculating the mean and standard deviation. Calculation and comparison were performed using Pearson correlation. Results: The Cobb's angle correction ranged from 53.4° ± 11.8° to 6.7° ± 5.2° (p < 0.001) in the open surgical correction group and from 51.2° ± 11.4° to 11.7° ± 5.8° (p < 0.001) in the minimally invasive surgery group before and after surgery, respectively. The percentage of curvature correction was 88.2% ± 8.0% and 77.7% ± 10.7% (p < 0.001) in the open surgical correction and minimally invasive surgery groups, respectively. The estimated blood loss was higher in the open surgical correction group than in the minimally invasive surgery group (208.7 ± 113.4 vs 564.3 ± 242.7 mL). Axial rotation was changed from 29.1°± 7.5 to 17.1°± 6.8 (p < 0.001) in the open surgical correction group and from 28.9°± 7.8 to 19.4°± 6.4 (p < 0.001) in the minimally invasive surgery group. The duration of surgery was shorter in the open surgical correction group than in the minimally invasive surgery group (266.6 ± 64.3 vs 346.2 ± 70.5 min). A positive correlation between time of operation and Cobb's angle correction (in °) in open surgical correction (r = 0.37) and minimally invasive surgery (r = 0.43) was found. Conclusion: The open surgical correction procedures were more effective than minimally invasive surgery in correcting the spinal curve. The increase in the duration of open surgical correction increases the estimated blood loss, but it also more significantly improves the correction of Cobb's angle. Level of evidence: III.

Indications and technical aspects of proximal gastrectomy.

According to the World Health Organization, gastric cancer is the fifth most common type of tumor, and is the third most common cause of tumor-associated death. Although gastric cancer incidence rates have decreased in the past few decades, the prevalence of proximal gastric cancer has been steadily rising in developed countries. Techniques regarding the improvement of treatment options must thus be developed. This can be achieved through incorporating both a wider use of endoscopic surgery (endoscopic mucosal resection-EMR, endoscopic submucosal dissection-ESD) and a review of applied surgical interventions. Even though there is no single international consensus available, the Japanese Gastric Cancer Association (JGCA) recommends proximal gastrectomy with D1+ lymphadenectomy in early gastric tumors. Despite recommendations from Asian guidelines and the short term outcomes of the KLASS 05 trial, surgical treatments in Western countries still rely on total gastrectomy. This is mostly due to technical and oncological challenges regarding surgical interventions in a proximal gastrectomy. However, the residual stomach after a proximal gastrectomy has been shown to diminish the incidence of dumping syndrome and anemia, and even improve postoperative quality of life (QoL). Therefore, it is necessary to define the place of proximal gastrectomy in the treatment of gastric cancers.

Perceived effectiveness of an innovative mobile-based serious game on the improvement of soft skills in minimally invasive surgical training.

INTRODUCTION: Soft skills have a pertinent role for the quality and efficient outcomes in minimally invasive surgical procedures that are difficult to practice due to time constraints, limited resources, and other logistical reasons. The literature says that serious games serve as better resources for learning soft skills but needs evaluation from stakeholders. This study explores the perceived effectiveness of serious gaming intervention as a learning tool to improve communication, collaborative skills among the residents in surgery, house officers and junior doctors. METHOD: A total of nine participants volunteered to take part in the exploratory study. During the study, the participants responded to a pre-test quiz, followed by exploration of the game and a post-test quiz. The perceived perceptions on the effectiveness of the gaming intervention were collected on a five-point Likert scale questionnaire with open-ended questions. RESULTS: There was no significant difference in pre-test and post-test scores on communication and collaborative skills. Among the three themes, there was significant effect of usefulness of the application of improvement of soft skills (90% response); however, technicalities should be addressed (50% of responses). The qualitative feedback renders that, better graphics, tutorial run, user-friendly interface and controls, and enhanced 3D environment would enhance the efficacy of the prototype. CONCLUSION: An innovative mobile-based serious gaming intervention was developed and tested for its effectiveness as a resource to develop soft skills among surgeons in training. The results indicate that gamified interventions can serve as educational resources and supplement the self-directed learning in surgical education.

Prostatic artery embolization compared to transurethral resection of the prostate and prostatic urethral lift: a real-world population-based study.

BACKGROUND: There are growing interests for minimally invasive surgical techniques (MISTs) for the treatment of benign prostatic hyperplasia (BPH)-associated lower urinary tract symptoms (LUTS). Prostatic artery embolization (PAE) uses selective angioembolization of prostatic arteries, thereby reducing size to improve LUTS/BPH. However, real-world data comparing surgical outcomes between MISTs and tissue resective techniques are lacking. We assessed the differences in surgical outcomes between PAE, transurethral resection of the prostate (TURP), and prostatic urethral lift (PUL) in a real-world population for LUTS/BPH. METHODS: We present an observational population-based study of 12,902 men with BPH in New York State who received PAE, TURP, and PUL in outpatient and ambulatory surgery settings from 2014 to 2018. For short-term outcomes, we report 30-day and 90-day risks of readmission to inpatient and emergency room (ER) with/without complications and compared them across groups using χ2 tests and mixed-effect logistic regressions. For long-term outcomes, we report surgical retreatment and stricture rates using Kaplan-Meier failure curves and compared them using Log rank tests and Cox regression models. RESULTS: Of 12 902 men, 335 had PAE, 11,205 had TURP, and 1362 had PUL. PAE patients had the highest 30-day (19.9%) and 90-day (35.6%) risks of readmission to inpatient or ER (p < 0.01). Non-specific abdominal pain was the main diagnosis associated with 30-day and 90-day readmissions to inpatient or ER after PAE (14.3% and 26.8%, respectively). After 2 years of follow-up, PAE patients had the highest retreatment rate of 28.5% (95%CI 23.7-34.2%) compared to TURP (3.4% (95%CI 3.1-3.8%)) and PUL (8.5% (95%CI 5.6-12.9%)) (p < 0.001). CONCLUSION: In a real-world population, PAE was associated with the most frequent 30-day and 90-day readmission to inpatient or ER and the highest retreatment rate among all surgical techniques even when controlled for individual patient comorbidities and surgical volume.

Enhanced Photoacoustic Visualisation of Clinical Needles by Combining Interstitial and Extracorporeal Illumination of Elastomeric Nanocomposite Coatings.

Ultrasound (US) image guidance is widely used for minimally invasive procedures, but the invasive medical devices (such as metallic needles), especially their tips, can be poorly visualised in US images, leading to significant complications. Photoacoustic (PA) imaging is promising for visualising invasive devices and peripheral tissue targets. Light-emitting diodes (LEDs) acting as PA excitation sources facilitate the clinical translation of PA imaging, but the image quality is degraded due to the low pulse energy leading to insufficient contrast with needles at deep locations. In this paper, photoacoustic visualisation of clinical needles was enhanced by elastomeric nanocomposite coatings with superficial and interstitial illumination. Candle soot nanoparticle-polydimethylsiloxane (CSNP-PDMS) composites with high optical absorption and large thermal expansion coefficients were applied onto the needle exterior and the end-face of an optical fibre placed in the needle lumen. The excitation light was delivered at the surface by LED arrays and through the embedded optical fibre by a pulsed diode laser to improve the visibility of the needle tip. The performance was validated using an ex-vivo tissue model. An LED-based PA/US imaging system was used for imaging the needle out-of-plane and in-plane insertions over approach angles of 20 deg to 55 deg. The CSNP-PDMS composite conferred substantial visual enhancements on both the needle shaft and the tip, with an average of 1.7- and 1.6-fold improvements in signal-to-noise ratios (SNRs), respectively. With the extended light field involving extracorporeal and interstitial illumination and the highly absorbing coatings, enhanced visualisation of the needle shaft and needle tip was achieved with PA imaging, which could be helpful in current US-guided minimally invasive surgeries.

A honeybee stinger-inspired self-interlocking microneedle patch and its application in myocardial infarction treatment.

Weak tissue adhesion remains a major challenge in clinical translation of microneedle patches. Mimicking the structural features of honeybee stingers, stiff polymeric microneedles with unidirectionally backward-facing barbs were fabricated and embedded into various elastomer films to produce self-interlocking microneedle patches. The spirality of the barbing pattern was adjusted to increase interlocking efficiency. In addition, the micro-bleeding caused by microneedle puncturing adhered the porous surface of the patch substrate to the target tissue via coagulation. In the demonstrative application of myocardial infarction treatment, the bioinspired microneedle patches firmly fixed on challenging beating hearts, significantly reduced cardiac wall stress and strain in the infarct, and maintained left ventricular function and morphology. In addition, the microneedle patch was minimally invasively implanted onto beating porcine heart in 10 minutes, free of sutures and adhesives. Therefore, the honeybee stinger-inspired microneedles could provide an adaptive and convenient means to implant patches for various medical applications. STATEMENT OF SIGNIFICANCE: Adhesion between tissue and microneedle patches with smooth microneedles is usually weak. We introduce a novel barbing method of fabricating unidirectionally backward facing barbs with controllable spirality on the microneedles on microneedle patches. The microneedle patches self-interlock on mechanically dynamic beating hearts, similar to honeybee stingers. The micro-bleeding and coagulation on the porous surface provide additional adhesion force. The microneedle patches attenuate left ventricular remodeling via mechanical support and are compatible with minimally invasive implantation.

Interrogating the Impassable: A Case Series and Literature Review of Unilateral SPECT-CT Groin Visualization in Men With Penile Cancer.

Penile squamous cell carcinoma (SCC) is a rare malignancy, which is known to invade local inguinal lymph nodes prior to progressing to the pelvis. Dynamic sentinel lymph node biopsy (DSLNB) is a standard for the minimally invasive assessment of lymphadenopathy in patients with subclinical groin metastasis. Hybrid 99mTc Single-Photon Emission Computed Tomography (SPECT-CT) has been shown to increase the accuracy of identifying first draining "sentinel" nodes (SN). Unilateral inguinal visualization on SPECT-CT is a rare presentation, which may increase the likelihood of a false negative SN biopsy. Retrospective analysis from three-penile cancer uro-oncologists in Melbourne, Australia identified 78 groins undergoing DSLNB for intermediate/high risk primary disease. Unilateral SPECT-CT results were observed in four patients suggesting a functional pattern of lymph diversion. Analysis confirmed malignancy (n = 2), sarcoidosis (n = 1), and evidence of local inflammation in SPECT-CT negative groins. Findings re-iterate the role of SPECT-CT a pre-operative adjunct. Experienced multimodal groin assessment using palpation, SPECT-CT, lymphoscintigraphy, and blue dye tracking remains paramount. Unilateral SN on pre-operative SPECT-CT in men with intermediate/high-risk penile SCC should elicit a higher degree of clinical suspicion. We recommend a low threshold for recommending radical inguinal lymph node dissection (ILND) for groins refractory to minimally invasive assessment.

Real-world data comparing minimally invasive surgeries for benign prostatic hyperplasia.

OBJECTIVES: To assess the differences in surgical outcomes between the prostatic urethral lift (PUL) and previous thermal energy procedures for the treatment of benign prostatic hyperplasia (BPH). METHODS: We present an observational population-based study of 2694 men with BPH in New York State and California who received PUL, transurethral needle ablation (TUNA), or transurethral microwave therapy (TUMT) in outpatient and ambulatory surgery settings from 2005 to 2018. For these surgical procedures, short-term outcomes were reported and compared using a Chi-square test and mixed-effect logistic regressions. Long-term outcomes were described using Kaplan-Meier failure curves and compared using a Log-rank test and Cox regressions. RESULTS: A significant portion of PUL patients had a comorbidity count ≥ 2 (n = 838, 37.0%). PUL exhibited the lowest 30 day and 90-day inpatient or ER readmission rates among all surgical techniques except for 90-day ER readmission (p < 0.05). No differences were observed for 1- and 3-year risks of reoperation between PUL [5.5% (95% CI 4.4-6.8%) and 14.9% (95% CI 10.9-20.1%)], TUNA [7.4% (95% CI 5.0-10.9%) and 11.3% (95% CI 8.3-15.4%)] and TUMT [8.5% (95% CI 4.7-15.2%) and 15.3% (95% CI 9.5-24.0%)]. 1- and 3-year risks of stricture development for PUL were 0.2% (95% CI 0.0-0.7%) and 0.2% (95% CI 0.0-0.07%), respectively. CONCLUSION: In a patient population with chronic conditions, patients treated with PUL exhibited similar 30- and 90-day inpatient or ER readmission rates when compared to previous reports. However, 1- and 3-year reoperation risks for PUL closely resembled previous thermal energy surgical procedures.

Intracranial Pressure and Cerebral Perfusion Pressure in Large Spontaneous Intracranial Hemorrhage and Impact of Minimally Invasive Surgery.

Introduction: We investigated the effect of hematoma volume reduction with minimally invasive surgery (MIS) on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in patients with large spontaneous intracerebral hemorrhage (ICH). Methods: Post-hoc analysis of the Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation (MISTIE III) study, a clinical trial with blinded outcome assessments. The primary outcome was the proportion of ICP readings ≥20 and 30 mmHg, and CPP readings <70 and 60 mm Hg. Secondary outcomes included major disability (modified Rankin scale >3) and mortality at 30 and 365 days. We assessed the relationship between proportion of high ICP and low CPP events and MIS using binomial generalized linear models, and outcomes using multiple logistic regression. Results: Of 499 patients enrolled in MISTIE III, 72 patients had guideline based ICP monitors placed, 34 in the MIS group and 38 in control (no surgery) group. Threshold ICP and CPP events ≥20/ <70 mmHg occurred in 31 (43.1%) and 52 (72.2%) patients respectively. On adjusted analyses, proportion of ICP readings ≥20 and 30 mmHg were significantly lower in the MIS group vs. control group [Odds Ratio (OR) 0.27, 95% Confidence Interval [CI] 0.11-0.63 (p = 0.002); OR = 0.18, 0.04-0.75, p = 0.02], respectively. Proportion of CPP readings <70 and 60 mm Hg were also significantly lower in MIS patients [OR 0.31, 95% CI 0.15-0.63 (p = 0.001); OR 0.30, 95% CI 0.11-0.83 (p = 0.02)], respectively. Higher proportions of CPP readings <70 and 60 mm were significantly associated with short term mortality (p = 0.04), and (p = 0.006), respectively. Long term mortality was significantly associated with higher proportion of time with ICP ≥ 20 (p = 0.04), ICP ≥ 30 (p = 0.04), and CPP <70 mmHg (p = 0.01). Conclusion: Our results are consistent with the hypothesis that surgical reduction of ICH volume decreases proportion of high ICP and low CPP events and that these variables are associated with short- and long-term mortality.

Towards development of a tele-mentoring framework for minimally invasive surgeries.

BACKGROUND: Tele-mentoring facilitates the transfer of surgical knowledge. The objective of this work is to develop a tele-mentoring framework that enables a specialist surgeon to mentor an operating surgeon by transferring information in a form of surgical instruments' motion required during a minimally invasive surgery. METHOD: A tele-mentoring framework is developed to transfer video stream of the surgical field, poses of the scope and port placement from the operating room to a remote location. From the remote location, the motion of virtual surgical instruments augmented onto the surgical field is sent to the operating room. RESULTS: The proposed framework is suitable to be integrated with laparoscopic as well as robotic surgeries. It takes on average 1.56 s to send information from the operating room to the remote location and 0.089 s for vice versa over a local area network. CONCLUSIONS: The work demonstrates a tele-mentoring framework that enables a specialist surgeon to mentor an operating surgeon during a minimally invasive surgery.

Tactile Sensing for Minimally Invasive Surgery: Conventional Methods and Potential Emerging Tactile Technologies.

As opposed to open surgery procedures, minimally invasive surgery (MIS) utilizes small skin incisions to insert a camera and surgical instruments. MIS has numerous advantages such as reduced postoperative pain, shorter hospital stay, faster recovery time, and reduced learning curve for surgical trainees. MIS comprises surgical approaches, including laparoscopic surgery, endoscopic surgery, and robotic-assisted surgery. Despite the advantages that MIS provides to patients and surgeons, it remains limited by the lost sense of touch due to the indirect contact with tissues under operation, especially in robotic-assisted surgery. Surgeons, without haptic feedback, could unintentionally apply excessive forces that may cause tissue damage. Therefore, incorporating tactile sensation into MIS tools has become an interesting research topic. Designing, fabricating, and integrating force sensors onto different locations on the surgical tools are currently under development by several companies and research groups. In this context, electrical force sensing modality, including piezoelectric, resistive, and capacitive sensors, is the most conventionally considered approach to measure the grasping force, manipulation force, torque, and tissue compliance. For instance, piezoelectric sensors exhibit high sensitivity and accuracy, but the drawbacks of thermal sensitivity and the inability to detect static loads constrain their adoption in MIS tools. Optical-based tactile sensing is another conventional approach that facilitates electrically passive force sensing compatible with magnetic resonance imaging. Estimations of applied loadings are calculated from the induced changes in the intensity, wavelength, or phase of light transmitted through optical fibers. Nonetheless, new emerging technologies are also evoking a high potential of contributions to the field of smart surgical tools. The recent development of flexible, highly sensitive tactile microfluidic-based sensors has become an emerging field in tactile sensing, which contributed to wearable electronics and smart-skin applications. Another emerging technology is imaging-based tactile sensing that achieved superior multi-axial force measurements by implementing image sensors with high pixel densities and frame rates to track visual changes on a sensing surface. This article aims to review the literature on MIS tactile sensing technologies in terms of working principles, design requirements, and specifications. Moreover, this work highlights and discusses the promising potential of a few emerging technologies towards establishing low-cost, high-performance MIS force sensing.

Contactless acoustic micro/nano manipulation: a paradigm for next generation applications in life sciences.

Acoustic actuation techniques offer a promising tool for contactless manipulation of both synthetic and biological micro/nano agents that encompass different length scales. The traditional usage of sound waves has steadily progressed from mid-air manipulation of salt grains to sophisticated techniques that employ nanoparticle flow in microfluidic networks. State-of-the-art in microfabrication and instrumentation have further expanded the outreach of these actuation techniques to autonomous propulsion of micro-agents. In this review article, we provide a universal perspective of the known acoustic micromanipulation technologies in terms of their applications and governing physics. Hereby, we survey these technologies and classify them with regards to passive and active manipulation of agents. These manipulation methods account for both intelligent devices adept at dexterous non-contact handling of micro-agents, and acoustically induced mechanisms for self-propulsion of micro-robots. Moreover, owing to the clinical compliance of ultrasound, we provide future considerations of acoustic manipulation techniques to be fruitfully employed in biological applications that range from label-free drug testing to minimally invasive clinical interventions.

Management of COVID-19-Positive Pediatric Patients Undergoing Minimally Invasive Surgical Procedures: Systematic Review and Recommendations of the Board of European Society of Pediatric Endoscopic Surgeons.

Introduction: Hospital response to the COVID-19 outbreak has involved the cancellation of elective, deferrable surgeries throughout Europe in order to ensure capacity for emergent surgery and a selection of elective but non-deferrable surgeries. The purpose of this document is to propose technical strategies to assist the pediatric surgeons to minimize the potential aerosolization of viral particles in COVID-19 patients undergoing urgent or emergent surgical treatment using laparoscopic approaches, based on the currently available literature. The situation and recommendations are subject to change with emerging information. Materials and Methods: The Scientific Committee and the Board of the European Society of Pediatric Endoscopic Surgeons gathered together in order to address the issue of minimally invasive surgery during this COVID-19 pandemic. A systematic search through PubMed, Embase, and World Wide Web of the terms "COVID-19," "Coronavirus," and "SARS-CoV-2" matched with "pneumoperitoneum," "laparoscopy," "thoracoscopy," "retroperitoneoscopy," and "surgery" was performed. Non-English language papers were excluded. A PRISMA report was performed. Criticalities were identified and a consensus was achieved over a number of key aspects. Results: We identified 121 documents. A total of 11 full-text documents were assessed to address all concerns related to the adoption of minimally invasive surgery. All aspect of pediatric minimally invasive surgery, including elective surgery, urgent surgery, laparoscopy, thoracoscopy, retroperitoneoscopy, and pneumoperitoneum creation and maintainance were extensively addressed through systematic review. A consensus regarding urgent laparoscopic procedures, setting and operation techniques was obtained within the Committee and the Board. Conclusions: The ESPES proposes the following recommendations in case minimally invasive surgery is needed in a COVID-19 positive pediatric patients: (1) consider conservative treatment whenever safely possible, (2) dedicate a theater, columns and reusable laparoscopic instrumentation to COVID-19 pediatric patients, (3) prefer disposable instrumentation and cables, (4) use low CO2 insufflation pressures, (5) use low power electrocautery, (6) prefer closed-systems CO2 insufflation and desufflation systems, and (7) avoid leaks through ports. These recommendations are subject to change with emerging information and might be amended in the near future.

Use of hemostatic agents for surgical bleeding in laparoscopic partial nephrectomy: Biomaterials perspective.

In recent years, there was an abrupt increase in the incidence of renal tumors, which prompt up the appearance of cutting-edge technology, including minimally invasive and organ-preserving approaches, such as laparoscopic partial nephrectomy (LPN). LPN is an innovative technique used to treat small renal masses that have been gaining popularity in the last few decades due to its promissory results. However, the bleeding control remains the main challenge since the majority of currently available hemostatic agents (HAs) used in other surgical specialities are inefficient in LPN. This hurried the search for effective HAs adapted for LPN surgical peculiarities, which resulted on the emergence of different types of topical HAs. The most promising are the natural origin HAs because of their inherent biodegradability, biocompatibility, and lowest toxicity. These properties turn them top interests' candidates as HAs in LPN. In this review, we present a deep overview on the progress achieved in the design of HAs based on natural origin polymers, highlighting their distinguishable characteristics and providing a clear understanding of their hemostat's role in LPN. This way it may be possible to establish a structure-composition properties relation, so that novel HAs for LPN can be designed to explore current unmet medical needs.
