ABSTRACT

In recent years, the incidence of single-gene nephrolithiasis has been increasing year by year. With the application of whole-genome analysis and whole-exome sequencing technology, the etiology of single-gene mutations leading to the development of urinary calculi has been extensively verified. Therefore, this article reviews the research on urinary calculi-related genetic diseases at home and abroad, and introduces transport proteins and channels; ions, protons and amino acids. The role of urinary calculi in the majority of clinicians realizes the significance of genetic testing in such diseases, thereby increasing the understanding of genetically related urinary calculi and improving the level of clinical diagnosis and treatment.

ABSTRACT

Benign prostatic hyperplasia (BPH) is a slowly progressing benign disease. Some patients still have to receive operation. If surgical treatement time is not proper, it may increase the risk of operation and reduce therapeutic effect. However, there is still lack an effective method to evaluate the optimal timing of BPH surgery. The large-scale, multi-center, high-quality clinical trials are needed to clarify the reasonable solutions.

ABSTRACT

Traditional expulsive methods,such as a high fluid intaking,more physical activity and medical expulsive therapy,was aimed at increasing voiding volume,frequency and strength of ureter movement,dilating ureter to detach the stone from mucosa and facilitate the stone clearance.It is usually termed as "passive lithecbole".The external physical vibration lithecbole system has gradually attracted the urologist's attention in recent years.This system develops a simple harmonic to drive the stone explusion along the urinary tract,which was named this new concept as " active lithecbole".The clinic safety and efficacy of active lithecbole has been proved during recent 5 years.In this paper,we reviewed the treatment of upper urinary tract stone from passive lithecbole to active lithecbole,and discussed the innovation of this concept altering.

ABSTRACT

Objective To assess the safety and efficacy of a novel technology referred to as percutaneous ureteroscopic laser deroofing in the management of renal cysts.Methods From November 2014 to August 2016,59 patients having surgical indications with renal cysts were enrolled and evaluated by ultrasound and CT scan.Of all the 59 patients,36 were males and 23 were females.Their mean age was 46 years (ranging 35-64 years).41 patients complained about the reported flank and abdominal pain.18 patients were found by imaging examination.Their mean diameter of cyst was 6.3cm(ranging 4.9-9.1cm).In regards to the 59 patients,include 6 patients suffered with parapelvic cysts and 4 patients suffered with renal cyst complicated with ipsilateral renal calculi.Their mean stone surface area was 5.7 cm2 (ranging 3.4-9.8 cm2).All of the patients received combined spinal and epidural analgesia or paravertebral nerve block anesthesia.Patients were placed in the prone position for percutaneous puncture and tract dilation.Under ultrasound guidance,an eighteen gauge needle was placed inside the cyst cavity percutaneously,a metal guidewire was introduced followed by sequential dilation up to F26-28.9.8F rigid ureteroscope was inserted through the Amplazt access sheath and advanced into the cyst cavity.Then sheath and ureteroscope both returned to the exterior cyst together.Cyst wall was dissociated from perirenal adipose tissue by used ureteroscope.A majority of the collapsed cyst wall was grasped and gently pulled towards the Amplazt sheath interior using grasping forceps and incised using either Thulium (Power 40 ~50W) or Holmium laser(Power 60 ~70W) and was taken for pathological examination.Nephrostomy tube was left in place for 2-3 days and removed before discharge.For parapelvic cysts patients,ureter stent was inserted into the renal pelvis i n the dorsal lithotomy position firstly.Patients were then placed in the prone position for percutaneous puncture and tract dilation.Laser was used to incise cyst wall towards identified pelvis to create a permanent communication between the cyst and adjacent renal collecting system.F6 double-J stent was inserted into the cyst cavity at the end to prevent auto-closure for at most two months.F22 nephrostomy tube was left in renal pelvis for two weeks.For renal cyst complicated with ipsilateral renal calculi patients,a puncture was created targeting the stone through the cyst,after fragmenting and extracting the stone,the same laser was used to deroof the cyst.More than 50% reduction in cyst volume was considered a success.The perioperative complications,hospitalization days and the effective rate of surgery were evaluated.Results All operations were conducted without intraoperative complications such as bleeding,urinary leakage or injury of the renal parenchyma and the adjacent organs.The hospital stay after the surgery was 2-4 days (mean 2.5 days).After 3-12 months follow-up (mean 8.1 months),patients underwent imaging examinations.42 out of 59 cases were completely resolved,15 were reduced to less than 50%,the total effective rate for the operation is 96.6% (57/59).4 patients with ipsilateral renal calculi were completely clear.However,two cases failed probably due to incomplete resection and follow treated with laparoscopic renal cyst deroofing.Conclusions Percutaneous ureteroscopy renal cyst laser deroofing is a safe,effective,less invasive,which can be performed in any endourological center without the need of special instruments and training.

Objective To assess the clinical safety and feasibility for ultrasound guided paravertebral block anesthesia of percutaneous nephrolithotomy.Methods Between December 2015 to June 2016,180 patients with renal or ureteral calculi were enrolled and evaluated with uhrasonography and CT scan.Of all the 180 patients,108 males and 82 females.Their mean age was 39 years (23-71 years).The clinical characteristics of the patients in each group,such as age,gender,BMI index,ASA status,mean arterial pressure and disease type had no significant differences (P > 0.05).These patients were randomized into general anesthesia group (G group),combined spinal epidural anesthesia group (C group) and paravertebral nerve block anesthesia group (P group).G group:35 males and 25 females.Their mean age was (40.1 ± 11.8) years and BMI was (25.1 ± 3.8) kg/m2;Renal calculi 52 cases,ureteral calculi 8 cases,Average maximum stone diameter was (2.6 ± 0.8)cm.C group:38 males and 22 females.Their mean age was (39.7 ± 12.4) years and BMI was (24.6 ± 4.1) kg/m2;Renal calculi 54 cases,ureteral calculi 6 cases,Average maximum stone diameter was (2.4 ± 0.8) cm.P group:35 males and 25 females.Their mean age was (38.9 ± 12.7) years and BMI was (25.4 ± 4.0) kg/m2;Renal calculi 51 cases,ureteral calculi 9 cases,Average maximum stone diameter was (2.5 ± 0.7) cm.Periprocedural Vital signs,complications,the times of anal discharging gas and postoperative feeding,hospitalized day and expense in these three groups were evaluated.Results Major intraoperative or postoperative complications did not occur in all of the patients.Mean arterial pressure decreased during preoperative changing positions was observed in group G (mean decreased 8.8 mmHg)and group C (mean decreased 1.9 mmHg),with significant difference in intra-group (P < 0.05).Postoperative nausea and vomiting was observed in 8 and 2 patients of group G and group P,respectively (P < 0.05).Postoperative pain was observed in 2 and 7 patients of group C and group P,respectively (P > 0.05).In addition,group P had early post operation feeding time [(6.4 ± 2.4) h],shorter hospitalized day [(4.5 ± 1.1) d] and lower hospitalized expense compared with other groups (P < 0.05).Conclusions Ultrasound guided paravertebral block can provide safe and reliable surgical anesthesia for percutaneous nephrolithotomy.
