The purpose of the review: The analysis of the components of enhanced recovery after surgery (ERAS) protocols in urologic surgery. Recent findings: ERAS protocols has been studied for over 20 years in different surgical procedures, mostly in colorectal surgery. The concept of improving patient care and reducing postoperative complications was also applied to major urologic surgery and especially procedure of radical cystectomy. This procedure is technically challenging, due to a major surgical resection and high postoperative complication rate that may reach 65%. Several clinical pathways were introduced to improve perioperative course and reduce the length of hospital stay. These protocols differ from ERAS modalities in other surgeries. The reasons for this are longer operative time, increased risk of perioperative transfusion and infection, and urinary diversion achieved using transposed intestinal segments. Previous studies in this area analyzed the need for mechanical bowel preparation, postoperative nasogastric tube decompression, as well as the duration of urinary drainage. Furthermore, the attention has also been drawn to perioperative fluid optimization, pain management, and bowel function. Summary: Notwithstanding partial resemblance between the pathways in major urologic surgery and other pelvic surgeries, there are still scarce guidelines for ERAS protocols in urology, which is why further studies should assess the importance of preoperative medical optimization, implementation of thoracic epidural anesthesia and analgesia, and perioperative nutritional management.

Study aimed to investigate relationship between oxidative stress markers and postoperative recovery in woman after abdominal hysterectomy, as well as to test the hypothesis that different analgesics differently influence redox status. The quality of recovery was evaluated with a QoR-40 questionnaire in fifty-one patients who underwent abdominal hysterectomy, preoperatively and on the 1^st, 2^nd, 3^rd postoperative days (POD1,2,3). Blood samples were collected at baseline (T0), 3 (T1), 24 (T2), 48 (T3) and 72 (T4) hours after surgery. Oxidative stress markers concentrations (TBARS, NO₂ ⁻, H₂O₂, O₂ ⁻ ) as well as antioxidative enzymes (SOD, CAT, and GSH) were analyzed. QoR-40 total score significantly declined on POD1 and POD2 and returned to baseline levels on POD3 (p0.05). Changes in TBARS levels from T0 to T3 were statistically significant between the study subgroups primarily due to increase of the concentrations in patients receiving paracetamol (p=0.031). Patients age, duration of surgery and cigarette smoking status showed significant influcences on and association with some oxidative stress response markers (TBARS, O₂ ⁻, CAT) (p<0.05). Women who underwent hysterectomy had significant changes of H₂O₂ and TBARS activity however, those changes were not associated with changes of QoR-40 total scores during recovery.

Background and Objectives: Coagulation disorders during COVID-19 infection are associated with a poorer prognosis and higher disease severity because thrombosis and inflammation are two processes that interfere with each other. A very important issue for clinicians is timely and adequate hemostasis and inflammation monitoring to prevent and treat potentially lethal consequences. The aim of this study was to identify specific hemostatic parameters that are associated with a higher risk of intrahospital mortality. Materials and Methods: This study was approved by the Ethics Committee of the Clinical Center Nis in Serbia. One hundred and forty-two patients presented with COVID-19 ARDS and were admitted to the ICU in the Clinic for Anesthesiology at the Clinical Center Nis from 14 April 2020 to 25 May 2020. Upon admission, blood was collected for biochemical and coagulation testing. The data obtained were analyzed using the Statistical Package for Social Sciences (SPSS v. 25, Chicago, IL, USA). Results: Among all the parameters assessed, older age; increased levels of fibrinogen, INR, D-dimer, and presepsin; and higher results in the platelet aggregation tests (aggregation induced by adenosine diphosphate based on the ADP test (AU/min), aggregation induced by arachidonic acid based on the ASPI test (AU/min), and aggregation induced by thrombin based on the TRAP test (AU/min)) and some assays of the viscoelastic test (clot amplitude after 5 min in the extrinsic coagulation pathway based on the A5 EX-test (mm), clot amplitude after 10 min in the extrinsic coagulation pathway based on the A10 EX-test (mm), clot amplitude after 5 min regarding functional fibrinogen based on the A5 FIB-test (mm), clot amplitude after 10 min regarding functional fibrinogen based on the A10 FIB-test (mm), and maximum clot firmness based on the MCF FIB-test (mm)); and lower values of viscoelastic clotting time in the extrinsic coagulation pathway based on the CT EX-test (s) were significantly correlated with mortality. In the multivariate analysis, D-dimer levels above 860 ng/mL, higher TRAP test value bins, and values above the normal reference range of the A10 FIB test were found to be independent predictors of mortality. Conclusions: Sophisticated hemostasis parameters can contribute to early risk assessment, which has initially been performed only on the basis of patients’ clinical status. Hypercoagulability is the main coagulation disorder in COVID-19 infection.

Short bowel syndrome (SBS) develops when the remaining intestine is unable to sustain adequate nutrient and electrolyte absorption following extensive bowel resection. The condition is characterized by malabsorption and significant fluid losses which lead to dehydration and progressive weight loss, thus promoting patient dependence on parenteral fluids or nutrition. After an initial acute phase marked by accelerated intestinal transit and gastric hypersecretion, long-term clinical outcomes are largely determined by the capacity of the remaining bowel for intestinal adaptation—a sustained process of structural, functional, and molecular remodeling that enhances absorptive efficiency and restores fluid and nutrient homeostasis. This review summarizes the key histological and cellular features of the adaptive response, including crypt and villus remodeling, mucosal hyperplasia, and smooth muscle hypertrophy, and integrates emerging concepts in crypt biology that define the dynamic cross-talk between intestinal stem cells and the mesenchymal niche, together with their upstream regulatory pathways.

Percutaneous nephrostomy and ureteral stenting are temporary treatments for the upper urinary tract obstruction. The aim of this study was to evaluate the efficacy of these two methods by comparing complications, placement success, urinary symptoms, urine culture analyses prior to derivation placement and derivation removal and success of stone elimination after extracorporeal shock wave lithotripsy (ESWL). This prospective study included 157 patients with supravesical obstruction caused by ureteral stones. Eighty-one patients underwent percutaneus nephrostomy, and JJ stent was inserted in seventy-six (76) patients. After resolving the obstruction, ESWL was performed in all patients. There were no statistically significant differences in success of the urinary derivation placement, the urine culture results before and after placement and success of ESWL treatment between the two studied groups (p>0.05). Urinary symptoms (dysuria, hematuria, urinary urgency, frequent urination during the day) were significantly more present in patients with a JJ stent and this difference was statistically significant for each symptom (p<0.001). Major complications were verified in 2 (2.46%) patients with PCN catheter, and in 7 (9.2%) patients in the group with the JJ stent. Minor complications were significantly more frequent in the group with the JJ stent compared to the group with PCN catheter (28.39% vs 60.52%, p<0.001). Percutaneous nephrostomy and JJ stenting are optimal methods for temporary treatment of supravesical obstruction caused by ureteral stones, with similar incidence of the following complications, except for the pain, which dominates in patients with the JJ stent. Urinary symptoms and asymptomatic bacteriuria are more common in patients with the JJ stent. If the ESWL treatment of ureteral stone is performed after urinary derivation placement, we can expect greater success in patients with the JJ stent
