We aimed to investigate the pre-operative predictive role of haematological parameters in patients with testicular torsion. The medical records of patients operated between January 2016 and November 2018 were retrospectively analysed. The demographic characteristics and complete blood count of the patients were recorded. We divided the patients who operated with testicular torsion into two groups: detorsion (Group 1) and orchiectomy (Group 2). A control group (Group 3) was created from healthy volunteers. All haematological parameters and other demographic data were compared between three groups. A total of 144 participants were included; Group 1, Group 2 and Group 3; 61, 27 and 56 respectively. The duration of symptoms and monocyte counts were found statistically significantly higher in patients undergoing orchiectomy than detorsion (p < .01). We found a significant difference in terms of neutrophil, lymphocyte, monocyte counts and neutrophil-lymphocyte ratio between patients with testicular torsion and controls. We also found that the monocytes count and symptom duration differed significantly between the detorsion group and the orchiectomy group. It is obvious that there is contradictory information according to the studies in the literature. We can say that the duration of symptoms and the number of monocytes are predictors of testicular viability.

Backgrounds: In the renal intrarenal stone surgery (RIRS) procedure, ureteral access sheath (UAS) is still used in the majority of surgeries to both protect the flexible ureteroscope (FURS) and reduce intrarenal pressure. ClearPETRA is a new UAS that has an integrated aspiration port. We aimed to evaluate the clinical outcomes and effectiveness of Aspiration-Assisted UAS (ClearPETRA) in the RIRS procedure. Methods: One thousand six hundred twenty patients who underwent RIRS between January 2021 and January 2024 were evaluated retrospectively and 512 patients were included in the study. According to stone size, patients with stones less than 2 cm and those with stones between 2 and 3 cm were analyzed separately. Patient's demographic data, stone size, body mass index, Extracoporeal Shockwave Lithotripsy (ESWL) history, stone side, stone density (Hounsfield Unit), operation time, stone-free rate (SFR), and the number of patients with sepsis were recorded. SFR was evaluated with kidney urinary bladder 3 months after surgery for opaque calculi. Nonopaque calculi patients were evaluated with noncontrast computed tomography 3 months after surgery. In the postoperative evaluation, patients with stones less than 4 mm were evaluated as SFR. P value of <0.01 was considered statistically significant. Results: Patient's demographic data, stone characteristics, and history of ESWL were similar in the ClearPETRA and UAS groups (P > .05). A total of 328 patients who underwent RIRS for stones less than 2 cm were included (80 ClearPETRA, 248 UAS). Length of hospital stay, operation time, SFR, secondary intervention, or postoperative sepsis (P ≥ .01) were similar in both groups. The incidence of postoperative fever was statistically significantly lower in the ClearPETRA group (P = .006). A total of 184 patients who underwent RIRS for stones between 2 and 3 cm were included (42 ClearPETRA, 142 UAS). In the ClearPETRA group, operation time was statistically significantly shorter (P = .002), SFR was statistically significantly higher (P = .003), and the number of fever and sepsis were statistically significantly less (P = .003 and 0.002, respectively). Conclusion: We found that ClearPETRA reduces the likelihood of postoperative fever after RIRS surgeries. Moreover, we can say that the use of ClearPETRA in RIRS, especially for stones larger than 2 cm, reduces the operation time, increases the SFR, and also reduces sepsis rates.

Introduction: We aimed to show the effect of patient information videos on preoperative anxiety before performing the percutaneous nephrolithotomy (PCNL) for kidney stones. Methods: This study was designed as a randomized, controlled trial with patients scheduled for PCNL operation for kidney stones. Demographic information, such as age, gender, and American Society of Anesthesiologists (ASA) score were collected. State-Trait Anxiety Inventory (STAI) was used to measure anxiety levels. Before informing the patients, anxiety levels were evaluated using the state anxiety scale (pre-information STAI-S and STAI-T). Patients were randomly divided into two groups: both groups received written and verbal information, while the “video” group was also shown a video of a PCNL procedure. The post-information anxiety levels of both groups were evaluated using STAI-S (post-information). Results: A total of 109 patients were included in the study and 50 patients were included in each group after nine patients were excluded. The participants in the two groups were similar in terms of gender distribution, mean age, and pre-information STAI-S scores. Post-information STAI-S scores were statistically significantly lower in the video group (p=0.02). There was no significant difference between post-information and pre-information STAI-S scores in the no-video group (p=0.86), whereas a significant decrease was found in post-information STAI-S scores in the video group (p<0.01). Conclusions: In addition to written and verbal information before PCNL operations, informative videos are an inexpensive, effective method to reduce preoperative anxiety levels. Video-based briefing may be routinely used in addition to preoperative verbal and written information.
