BSD only allows widening of the ostia of the maxillary, frontal and sphenoid sinuses. BSD offers shorter post-surgical recovery, and a more rapid return to work because of its less invasive and less traumatic nature.

Sinus pilonidalis (SP) is an acquired inflammatory disease, which is relatively common in the paediatric population. Surgery is indicated in symptomatic patients. In 2017, minimally invasive pilonidal sinus treatment (EPSiT) was adapted to the paediatric population.

To evaluate the first experience with minimally invasive endoscopic treatment of SP (PEPSiT) in children and adolescents in the Czech Republic.

A retrospective review of all consecutive paediatric patients who underwent PEPSiT from November 2018 to February 2020. The monitored parameters were demographics, perioperative course of the disease, surgery, length of hospitalisation, postoperative complications, healing, disease recurrence, and follow-up.

Seventeen patients were enrolled in the study. The median age at surgery was 17.1 years (range 12.5-18). The subjects comprised 76% males, and the median body mass index was 25.6 kg/m

(range 17-30.3 kg/m

). Thirteen patients underwent previous surgical treatment (76%) under local anaesthesia. The median duration of PEPSiT was 50 min (range 30-85 min). The subjective evaluation of pain by patients on the VAS scale was 0 on the day of discharge. There were no postoperative complications up to the 30

postoperative day. Two disease recurrences were successfully managed by re-PEPSiT. By the end of follow-up, 14/15 patients had healed. Two patients are still within 3 months of surgery, which is too soon to definitively evaluate possible recurrence of the disease.

These preliminary results show that PEPSiT is a highly promising method. It is safe and well-tolerated by patients (short hospital stay, quick return to normal life, low pain and analgesic consumption). Two recurrences of disease were treated by re-PEPSiT.

Current literature suggests various predictors related to the stone and patient, which could influence stone fragmentation and clearance rates.

To establish clinical characteristics of stone disease for patients undergoing extracorporeal shockwave lithotripsy (ESWL) which may predict the success of the procedure.

One hundred and nine patients with renal stone disease diagnosed by non-contrast computed tomography (NCCT) who underwent ESWL between January 2015 and December 2019 were included in the study. Endpoints patient being stone free (SF) or when < 4 mm fragments were detected. Age, gender, location, skin-to-stone distance, maximum stone length, stone volume, stone surface area, mean stone Hounsfield units (HU) and highest HU score were explored in uni- and multivariate regression analysis.

Stone size revealed the highest prognostic power for ESWL failure, where OR for stone volume and stone surface area were 1.06 (1.03-1.10) and 1.04 (1.02-1.06), respectively (all p < 0.01) while a tendency was observed for skin-to-stone distance 1.02 (1.00-1.03). The amount of energy applied during the procedure to one cubic millimeter of stone volume (SMLI/stone volume) was predictive for treatment success (OR = 0.60, 95% CI 0.41-0.87, p < 0.01). Stone volume (OR = 1.06, 95% CI 1.00-1.14, p = 0.01) and stone surface area (OR = 1.03, 95% CI 1.01-1.06, p = 0.02) remained as statistically significant prognostic factors for treatment failure.

Both greater stone volume and stone surface area, as well as lower power delivered per stone volume unit during the ESWL procedure, were found to be significant factors and could be useful to predict treatment failure.

Salvage lymph node dissection (sLND) using novel imaging methods is an interesting alternative to treat lymph node (LN) metastasis after radical prostatectomy (RP); however, recommendations for using sLND as such are still being developed.

To assess the clinical outcomes of prostate cancer (PCa) after fluorine-18-choline (18F-choline) positron emission tomography/computed tomography (PET/CT) guided sLND.

Ten patients who had undergone sLND under 18F-choline PET/CT guidance (positive nodes median 1, range 1-3) and had biochemical recurrence or persistence of prostate-specific antigen (PSA median PSA 2.05 ng/ml, range 0.8-8.4) after RP were enrolled in this retrospective study. Complete biochemical response (cBCR) after salvage surgery was defined as PSA < 0.2 ng/ml.

The median follow-up time after salvage surgery was 33 months. The median PSA level 6 weeks after sLND and at the end of follow-up was 0.93 and 2.95 ng/ml, respectively. At 6 weeks after targeted sLND only 1 patient had cBCR, whereas a PSA decrease was noted in 7 patients. No patient had cBCR at the end of follow-up.

Laparoscopic sLND in cases of LN metastatic PCa after RP is a feasible option with low morbidity. However, an initial cBCR occurs in a negligible proportion of patients, and a long-term response is unlikely to be achieved.

The effect of repeated cystoscopy on bladder cancer (BC) patient anxiety and feelings is rarely evaluated.

To compare the difference of patients' anxiety and subjective feelings caused by different cystoscopes.

We prospectively included 192 BC patients who accepted regular cystoscopy follow-up after transurethral resection of bladder tumor (TURBT) 93 in the flexible group and 99 in the rigid group. The method of anesthesia and the order of examinations were consistent between different groups. We analyzed the anxiety level before cystoscopy, the maximum pain during the examination and the change of lower urinary tract symptoms (LUTS) before and after cystoscopy. Meanwhile, we analyzed the rate of gross hematuria and pyuria after cystoscopy. The anxiety and pain levels were evaluated by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and visual analogue scale (VAS). LUTS was reflected by the Core Lower Urinary Tract Symptom Score (CLSS). read more We distinguished gender during analysis.

The median APAIS score of male patients undergoing flexible or rigid cystoscopy was 8 vs.
