ABSTRACT

Objective:To explore the clinical characteristics and treatment regimens of adrenal incidentaloma (AI) in children.Methods:Clinical data of 38 children with AI treated in the Department of Urology, Children′s Hospital of Nanjing Medical University from December 2016 to October 2021 were retrospectively analyzed.A total of 38 children were divided into neonatal group and non-neonatal group according to their age at first diagnosis.The neonatal group had 7 males and 9 females patients, of whom 7 cases were detected with AI during prenatal examinations, 9 cases were diagnosed postnatally.Four children in neonatal group had AI in the left adrenal gland and 12 cases in the right, with the maximum diameter of tumor (MDT) ranging from 16-48 mm.In the non-neonatal group, there were 14 males and 8 females patients aged 7 months and 1 day to 12 years and 1 month, and the MDT was 29-131 mm.Paired t test was used to compare the age and MDT of benign and malignant tumors. Results:In the neonatal group, 3 patients were surgically treated, with 2 cases and 1 case of neuroblastoma and teratoma confirmed by postoperative histology, respectively.The remaining 13 patients in the neonatal group were followed up for 1-31 months, with 8 cases and 5 cases of complete remission and significantly decreased tumor volume, respectively.In the non-neonatal group, there were 3, 9 and 10 patients received open biopsy, laparoscopic adrenalectomy, and open adrenalectomy, respectively.Of these 22 surgically treated cases, 8 cases had a benign lesion, including ganglioneuroma ( n=4), adrenocortical adenoma ( n=1), adrenal cyst ( n=1), teratoma ( n=1), and pheochromocytoma ( n=1); while 14 cases had a malignant lesion, including neuroblastoma ( n=8), ganglioneuroblastoma ( n=5), and adrenocortical carcinoma ( n=1). The mean age of patients with malignant tumors was significantly younger than those with benign tumors[(38.94±35.44) months vs.(95.89±41.43) months, t=3.63, P=0.001]. The mean MDT in malignant tumors was significantly longer than that of benign tumors[(64.43±25.20) mm vs.(41.44±15.66) mm, t=2.45, P=0.023]. Conclusions:AI in children has a high risk of malignancy.Therefore, more detailed examinations are needed to detect tumor markers and endocrinological parameters, and imaging tests such as non-contrast and CT examination should be performed as early as possible.AI in children is predominantly neuroblastic tumors.For non-neonatal patients, surgery should be performed as early as possible.For AI found in the neonatal period and prenatal examination, expectant management is feasible if the tumor is relatively small and limited to the adrenal gland without distant metastases.

ABSTRACT

Intelligent drug delivery is a promising strategy for cancer therapies. In recent years, with the rapid development of synthetic biology, some properties of bacteria, such as gene operability, excellent tumor colonization ability, and host-independent structure, make them ideal intelligent drug carriers and have attracted extensive attention. By implanting condition-responsive elements or gene circuits into bacteria, they can synthesize or release drugs by sensing stimuli. Therefore, compared with traditional drug delivery, the usage of bacteria for drug loading has better targeting ability and controllability, and can cope with the complex delivery environment of the body to achieve the intelligent delivery of drugs. This review mainly introduces the development of bacterial-based drug delivery carriers, including mechanisms of bacterial targeting to tumor colonization, gene deletions or mutations, environment-responsive elements, and gene circuits. Meanwhile, we summarize the challenges and prospects faced by bacteria in clinical research, and hope to provide ideas for clinical translation.

ABSTRACT

Objective:To evaluate the effect of goal-directed fluid therapy (GDFT) based on permissive high stroke volume variation (SVV) guidance on residual liver function in elderly patients undergoing laparoscopic hepatectomy.Methods:A total of 100 elderly patients of either sex, aged 65-80 yr, with body mass index of 18.5-24.9 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with Child-Pugh grade A or B, scheduled for elective laparoscopic hepatectomy, were divided into 2 groups ( n=50 each) by the random number table method: SVV-guided GDFT group (group SG) and CVP-guided fluid replacement group (group C). Intraoperative fluid management was divided into 2 stages.The first stage was from the start of surgery to the completion of liver resection, the SVV was maintained at 13%-20% in group SG, and the low CVP was maintained at 0-5 cmH 2O in group C. The second stage was from completion of liver resection to the end of the operation, SVV was maintained at 9%-13%, additional hydroxyethyl starch 3 ml/kg was given or repeatedly administered when SVV>13% (for 5 min) or when the response to previous fluid replacement was positive (SVV increased by more than 10%), and the infusion rate was slowed down when the SVV was 9%-13% in group SG, and CVP was maintained at 5-12 cmH 2O in group C. Mean arterial pressure and heart rate were recorded on admission to the operating room, at skin incision (T 1), at the start of liver resection (T 2), at completion of liver resection (T 3) and at the end of operation (T 4). The operation time, intraoperative blood loss, transfusion volume, urine volume and levels of serum lactic acid before operation and at the end of operation were recorded.Blood samples from the median cubital vein were collected at T 0-4 to measure blood glucose and cortisol concentrations.The concentrations of serum aspartate aminotransferase, alanine aminotransferase, total bilirubin and albumin were measured before operation, at 1, 3 and 5 days after operation, and prothrombin time, activated partial thromboplastin time, thrombin time and Fib were recorded.The concentrations of serum interleukin-6, tumor necrosis factor-alpha and C-reactive protein were measured by enzyme-linked immunosorbent assay before operation and at the end of operation, and the postoperative complications and length of hospital stay were recorded. Results:Compared with group C, mean arterial pressure and heart rate were significantly decreased at T 2, 3, blood loss was reduced, transfusion volume and urine volume were increased, prothrombin time and activated partial thromboplastin time were shortened at the end of operation, serum concentrations of interleukin-6 and lactic acid and concentrations of aspartate aminotransferase and alanine aminotransferase in serum at 5 days after operation were decreased, and the length of hospital stay was shortened in group SG ( P<0.05). Conclusions:GDFT based on permissive high SVV guidance can improve residual liver function in elderly patients undergoing laparoscopic hepatectomy.

ABSTRACT

Objective:To explore the clinical value of single-hole laparoscopic percutaneous extraperitoneal closure operation using a Kirschner wire assisted double-hook water-injection hernia needle in treating complicated pediatric oblique inguinal hernia.Methods:The clinical data of 366 children with oblique inguinal hernia treated in the Department of Urology Surgery, Children′s Hospital of Nanjing Medical University from December 2020 to October 2021 were retrospectively analyzed.According to the surgical methods, the children were divided into the ordinary crochet needle group and the Kirschner wire assisted group.Children treated by a single-port laparoscopic double hook water-injection hernia crochet needle (309 cases) were classified into the ordinary crochet needle group.Children treated by a single-port laparoscopic Kirschner wire assisted double hook water-injection hernia crochet needle (57 cases) were included in the Kirschner wire assisted group.The independent sample t-test and rank sum test was used to compare the relevant clinical indicators between the two groups. Results:Compared with the ordinary crochet needle group, children in the Kirschner wire assisted group were younger at surgery[(2.87±1.88) years vs.(4.91±2.39) years] and had larger hernia sacs [17 303.89(8 622.49, 37 295.42) mm 3vs.9 650.97(3 849.24, 17 539.51) mm 3]. The differences in the age at surgery and hernia sac volume were statistically significant ( t=-5.407, Z=-4.218; all P<0.001). There was no significant difference in body mass index between the 2 groups ( P>0.05). Taking hernias with sac volume >10 000 mm 3 as huge hernias, there were 70.18%(40/57 cases) and 47.25%(146/309 cases) of huge hernias in the Kirschner wire assisted group and the ordinary crochet needle group, respectively.The overall operation time of the Kirschner wire assisted group was significantly longer than that of the ordinary crochet needle group[(20(15, 20) min vs.15(15, 20) min] ( Z=-2.842, P<0.05). However, the operation time for huge oblique hernias with sac volume >10 000 mm 3 was not statistically significant between the 2 groups ( P>0.05). No recurrence in both groups was found during 6-16 months of follow-up. Conclusions:For complicated oblique inguinal hernia in children with a huge hernia or obvious retroperitoneal folds at the internal ring and heavy scar adhesion between the hernia sac and abdominal wall, the insertion of a Kirschner wire can help the hernia crochet needle to traverse the vas de-ferens and spermatic cord vessels smoothly.As a single port laparoscopic operation, the Kirschner wire assisted hernia crochet needle requires no addition of trocar holes and leaves only a small surgical scar.With good feasibility and safety, it is applicable for clinical popularization.

ABSTRACT

Objective:To study the relationship between serum osteopontin and osteopontin and type 2 diabetes mellitus (T2DM) complicated with coronary heart disease, and to evaluate the correlation between the levels of serum osteopontin and osteopontin with the severity of coronary artery lesions in T2DM patients.Methods:A total of 100 T2DM patients who were suspected to have stable coronary heart disease and underwent coronary angiography from November 2019 to December 2020 were selected from the Affiliated Hospital of Chengde Medical College, according to coronary angiography results, 60 patients with confirmed coronary heart disease were classified as the case group and 40 patients with non-coronary heart disease were classified as the control group for retrospective analysis. The clinical data and biochemical indicators of all patients were recorded, and Gensini score was calculated. The concentration of osteopontin and osteopontin in serum was quantitatively determined by double-antibody enzyme linked immunosorbent assay method. Independent sample t-test was used to compare the mean of normal distribution measurement data between the two groups. The non normal distribution data are represented by M ( Q1, Q3), and Mann Whitney U test is used for comparison between groups. Composition comparison between count data groups χ 2 inspection. Spearman correlation analysis was used to analyze the correlation between serum osteopontin and osteopontin and Gensini score in patients with T2DM. Results:Univariate analysis showed that serum osteopontin and osteopontin were (13.076(8.433, 23.552) μg/L) and (0.437(0.300, 0.630) μg/L) significantly higher in the case group than in the control group (6.367(4.605, 9.048) μg/L) and (0.299(0.196, 0.399) μg/L) respectively, with statistically significant differences ( Z=5.12, 3.28, all P<0.001). Multi-factor logistic regression analysis showed that osteoprotegerin ( OR=2.887, 95% CI:1.850-8.515, P=0.024) and osteopontin ( OR=13.109, 95%CI: 2.557-67.204, P=0.002) were associated with T2DM combined with coronary heart disease, and the risk of T2DM combined with coronary heart disease increased with higher levels of osteoprotegerin and osteopontin. Spearman correlation analysis showed that serum osteopontin and osteoprotegerin were positively correlated with Gensini score in T2DM patients ( r=0.591, 0.467; all P<0.05). Conclusion:Serum osteopontin and osteoprotegerin are associated with T2DM combined with coronary heart disease, and high serum osteopontin and osteoprotegerin are risk factors for T2DM combined with coronary heart disease; serum osteopontin and osteoprotegerin are positively correlated with the degree of coronary artery disease in T2DM patients.

ABSTRACT

Objective:To investigate the correlation between gamma-glutamyl transferase/high-density lipoprotein cholesterol ratio (GHR), neutrophil/lymphocyte ratio (NLR) and coronary heart disease (CHD), and evaluated its pathogenic risk and predictive value for CHD.Methods:A total of 694 patients admitted to our hospital from December 2017 to December 2018 for suspected CHD and coronary angiography were selected. According to the results of coronary angiography,the patients were divided into CHD group ( n=527) and non-CHD group ( n=167). The clinical data of all patients were recorded. Gamma-glutamyl transferase (GGT), high-density lipoprotein cholesterol (HDL-C) and other biochemical indicators were recorded. Neutrophils, lymphocyte count and other hematological indicators were recorded. GHR, NLR and Gensini scores of the patients were calculated. Clinical data and GHR, NLR and other indicators were compared between the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of GHR, NLR in CHD, and to determine the optimal cut-off value; Logstic regression analysis was used to investigate the risk factors of CHD.Spearman correlation analysis was used to analyze the correlation between serum OPN, OPG and Gensini score in patients with CHD. Results:The GHR and NLR were 32.59(21.05, 48.24) and 3.53(2.18, 8.46) significantly higher in the CHD group than in the non-CHD group 16.56(10.07, 25.21) and 2.20(1.45, 3.28) respectively, with statistically significant differences ( Z=11.094, 9.055, P<0.05). ROC curve analysis showed that the AUC of NLR and MLR in diagnosing CHD was 0.785 and 0.732( P<0.05). When the critical values of GHR and NLR respectively were 19.805 and 2.678, respectively, the diagnostic efficiency of CHD was the highest, and the sensitivity and specificity were 79.30%, 62.90% and 63.80%, 68.30%, and the AUC of GGT in diagnosing CHD was 0.628. When the critical value was 19.500, the sensitivity and specificity were 80.50% and 39.50%, respectively,the AUC of GHR was greater than that of GGT ( Z=12.973, P<0.05). Multivariate Logistic regression analysis showed that Smoking ( OR=2.887, 95% CI:1.850-4.505, P<0.05), hypertension ( OR=2.009, 95% CI: 1.311-3.080, P<0.05), fasting plasma glucose ( OR=1.109, 95% CI:1.034-1.189, P<0.05), age ≥60 years ( OR=1.567, 95% CI:1.179-2.415, P<0.05), NLR ≥2.687 ( OR=3.152, 95% CI:2.066-4.808, P<0.05) and GHR ≥19.805 ( OR=4.768, 95% CI:3.131-7.262, P<0.05) was an independent risk factor for CHD. After gradually adjustment for risk factors such as smoking, hypertensive, fasting plasma glucose, age ≥60 years and NLR ≥2.687, GHR ≥19.805 was still an independent risk factor for coronary heart disease(OR and 95% CI were 4.620 (3.049-7.000), 4.768 (3.131-7.262), 6.567 (4.408-9.810), 4.768 (3.131-7.262), 4.768 (3.131-7.262), respectively; all P<0.001). Spearman correlation analysis showed that GHR and NLR were positively correlated with Gensini score ( r=0.312, 0.394; all P<0.05). Conclusion:GHR and NLR were positively correlated with the severity of coronary artery disease, which is of significance in the diagnosis of coronary heart disease. NLR ≥2.687 and GHR ≥19.805 were independent risk factors for CHD. GHR was superior to GGT and HDL-C alone in the diagnosis of CHD,and has certain clinical application value

ABSTRACT

Objective:To evaluate the effect of permissive high stroke volume variability (SVV) on postoperative delirium (POD) in elderly patients undergoing laparoscopic hepatectomy.Methods:A total of 100 elderly patients of either sex, with body mass index of 18.5-24.9 kg/m 2, aged 65-80 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with Child-Pugh grade A or B, scheduled for elective laparoscopic hepatectomy, were divided into 2 groups ( n=50 each) using a random number table method: permissive high SVV group (group S) and control group (group C). Group S was given goal-directed fluid infusion with a target of high SVV (13%-20%), and fluid replacement was performed according to the intraoperative CVP in group C. Oxygen extraction ratio was calculated on admission to the operating room (T 0), at skin incision (T 1), at the beginning of liver resection (T 2), completion of liver resection (T 3) and at the end of operation (T 4). Intraoperative blood loss, volume of fluid infused and urine volume were recorded.Lactic acid concentrations were measured at T 0 and T 4.Regional cerebral oxygen saturation (rSO 2) was continuously recorded, and the maximum percentage of decrease in rSO 2 from baseline (rSO 2max%) was calculated.Peripheral venous blood samples were collected at 1 day before operation, at the end of operation, and at 1 and 3 days after operation to determine the concentrations of serum S100β and neuron-specific enolase.POD was evaluated at 1, 3 and 7 days after operation, and the hospitalization time was recorded. Results:Compared with group C, the intraoperative blood loss was significantly decreased, the volume of fluid infused and urine volume were increased, the lactic acid concentration at T 4, rSO 2max%, oxygen extraction ratio at T 2-4, serum S100β and neuron-specific enolase concentrations and incidence of POD at 1 and 3 days after operation were decreased, and the hospitalization time was shortened in group S ( P<0.05). Conclusion:Permissive high SVV can decrease the development of POD in elderly patients undergoing laparoscopic hepatectomy, which is related to reduction of cerebral oxygen metabolism.

ABSTRACT

Objective: To summarize the diagnosis and prognosis of adrenocortical carcinoma in children. Methods: Medical records of 10 pediatric patients with adrenocortical cancer treated in Children's Hospital of Nanjing Medical University from September 2010 to March 2018 were retrospectively reviewed, and their clinical manifestation, laboratory, auxiliary, and pathological examination results, and prognosis were analyzed. Results: The average age of all patients (5 male and 5 female pediatric patients) was (53.3+48.4) months. Clinical mani-festations included abdominal mass, hypertension, cortisol level, and peripheral precocious puberty. Laboratory tests showed that lactate dehydrogenase, neuroenolase, and cortisol levels were high in some patients, and sex hormones were abnormal. Auxiliary examination using the abdominal computed tomography enhancement showed irregular an adrenal gland, uneven density, necrosis, mass calcification, and some infiltration into the surrounding tissue. Pathological examination suggests tumor cell pleomorphism, more frequent pathological division, high mitotic index, abundant interstitial sinusoid, necrosis, tumor infiltration, vascular invasion, and Weiss score of≥3 points. Lactate acid dehydrogenase and cortisol levels; Weiss score; and tumor size, staging, and resection rate were not statistically different among prognostic factors. Conclusions: For pediatric patients with adrenal masses, the survival rate should be improved by combining the clinical manifestation, laboratory examination, and auxiliary examination for the early diagnosis of adrenocortical carcinoma and to select the appropriate treatment. Combined with pathological results, adrenocortical carcinoma can be well differentiated from other adrenal masses.

ABSTRACT

Objective To analyze the prognostic factors of adrenal tumor in children under 12 years of age. Methods A total of 90 children with 97 adrenal tumors admitted from June 2006 to August 2017 were selected in Children's Hospital of Nanjing Medical University.The age distribution,tumor type,biochemistry and tumor indicators, treatment,stage classification and prognosis were analyzed.Results There were 46 males and 44 females in 90 cases. Ages ranged from 4 days to 11 years and 1 month,with an average of (38.1 ± 31.3)months.The main clinical mani-festations were abdominal mass,fever and abdominal pain.Eighty cases (82.5%)underwent surgery,while 17 cases (17. 5%)did not.Open resection was performed in 48 cases,open partial resection in 11 cases,laparoscopic surgery in 10 cases,and just biopsy in 11 cases.The pathological examination showed 43 cases with neuroblastoma,13 cases with ganglioneuroblastoma,8 cases with ganglioneuroma,5 cases with adrenocortical carcinoma,3 cases with teratoma,1 case with pheochromocytoma,1 case with malignant rhabdoid tumor.Statistical analysis revealed that neuron-specific eno-lase(NSE)value of neuroblastoma and lactate dehydrogenase(LDH)value of cortical cancer increased significantly. The age was correlated with tumor stage,and patients had older age on stage Ⅳ.Complete resection in surgery was correlated with the stage of the tumor,as tumor in lower tumor stage seemed easier to be completely removed.Fifty-three cases (58.9%)were followed up for 2 months up to 11 years and 4 months.Forty-four cases survived and 9 ca-ses died.Higher tumor stage predicated worse prognosis.Conclusions Adrenal gland tumors need early diagnosis and active treatment.Earlier onset of age,complete surgical resection with patients have better prognosis.Complete resection of the disease was a key factor in the prognosis.

Aim To examine the effect of zacopride,a specific inward rectifier potassium channel(IK1)agonist,on L-thyroxine(T4)-induced ventricular remodeling and the underlying mechanism.Methods SD rats were randomly divided as control,L-thyroxine(L-thy,1 mg·kg-1·d-1,ig,10 d)model,L-thy +zacopride(5,15,50 μg·kg-1,respectively,ip),L-thy+zacopride(15 μg·kg-1)+chloroquine(7.5 μg·kg-1,ip)and L-thy+captopril(100 mg·kg-1·d-1,drinking water)groups.Echocardiography and cardiac hypertrophic indexes were measured to confirm the establishment of the ventricular remodeling model.The changes of IK1 and L-calcium current(ICa-L)were detected by whole cell patch clamp technique.The confocal microscopy and fluorescent indicator Fluo-4 were applied to examine the intracellular Ca2+ concentration([Ca2+]i)of isolated adult rat ventricular myocytes.Results L-thyroxine induced left ventricular hypertrophy with increased ratio of heart weight(HW)to body weight(HW·BW-1),ratio of left ventrical weight(LVW)to body weight(LVW·BW-1),left ventricular dimension in diastole(LVIDd),left ventricular dimension in systole(LVIDs),interventricular septum thickness(IVS)and decreased ejection fraction(EF),fractional shortening(FS)(P<0.01).Patch clamp data suggested IK1 was downregulated,while ICa-L was upregulated(P<0.01).In isolated adult cardiomyocytes,L-thyroxine increased the cell area and [Ca2+]i(P<0.01).Zacopride treatment obviously alleviated cardiac remodeling,improved cardiac function,reversed the changes of IK1 and ICa-L,and significantly attenuated intracellular calcium overload(P<0.01).The optimum dose of zacopride in vivo was 15 μg·kg-1 at which the effect was compared favourably with captopril,a classical anti-remodeling agent.Low-dose IK1 atagonist chloroquine could reverse the effect of zacopride(P<0.01).Conclusion Via activating IK1,zacopride could significantly decrease Ca2+ influx and intracellular calcium overload thereby inhibiting L-thyroxine-induced cardiac ventricular remodeling.

ABSTRACT

Objective To explore the diagnosis,treatment options and outcomes of patients with ureteropelvic junction obstruction(UPJO)and ureterovesical junction obstruction(UVJO). Methods Clinical records of 12 children with UPJO and UVJO who received treatment in Children′s Hospital of Nanjing Medical University from April 2008 to December 2015 were reviewed. Presentations included prenatal hydronephrosis and symptoms caused by urinary tract in-fections. Ultrasonography,intravenous pyelography,magnetic resonance imaging and renography were performed before surgery. Results Four patients underwent nephrostomy,followed by pyeloplasty and eventually,ureteroneocystostomy. Five patients underwent heterochronic pyeloplasty plus ureteroneocystostomy. Two patients received pyeloplasty only. And another patient underwent heterochronic nephrostomy plus ureteroneocystostomy. The 12 patients received a 2. 0 months to 2. 5 years′ follow - up. Recurrent urinary tract infection and abdominal pain were relieved after the treatment. Ultrasonography showed hydronephrosis reduced obviously after the surgery. Conclusions UVJO patients with unparallel hydronephrosis should be considered with the coexistence of UPJO. Retrograde pyelography(RPG)is recommended for the diagnosis. And the treatment includes both pyeloplasty and ureteroneocystostomy. The patients diagnosed with UPJO should be first managed with pyeloplasty or nephrostomy instead of RPG. Subsequently anterograde pyelography can be performed to decide if the patients need additional ureteroneocystostomy.

ABSTRACT

Objective To retrospectively analyze the efficacy of Onlay-tube-onlay urethroplasty used for one-stage repairing of severe hypospadias.Methods From May 2012 to October 2014, a total of 32 patients with severe hypospadias who underwent primary HR at Nanjing Medical University Affiliated Children Hospital were enrolled.Urethral opening was located in the penis and scrotum, and onlay-tube-onlay urethroplasty was performed in the patients who had severe penile curvature even after skin degloving. The average age was 2.8 years (7 months-13 years and 7 months), postoperative follow-up was 2 years and 1month on average ( 6 months -2 years and 11 months ), and clinical data including appearance, complications and uroflowmetry were documented.Results All of 32 surgeries were completed by one experienced pediatric urologist, and the urethral defect length was measured after penile curvature completely corrected.The postoperative complications included two cases of urinary fistula ( 6.25%) and 3 cases of urethral stricture (9.37%).Two cases of fistula were cured by one operation.Stricture of urethral external orifice was relieved after urethral dilation in 1 case, and another 2 cases underwent another operation.The straightening and appearance of penis were satisfactory and meatus was located at normal anatomical position postoperatively.Uroflow was shaped into bell or high platform.Conclusions Onlay-tube-onlay urethroplasty is a combination of Onlay and Duckeet surgery, with low complication rates.Fully stripping and preserving urethral plate decrease the occurrence of complications, especially stricture. Urethral plate transecting permitted penile straightening completely.Onlay-tube-onlay can be a good option for the patients with severe hypospadias.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the success rate, postoperative complications and cosmetic appearance of the perinatal flap (Mathieu) and the tubularized incised-plate (Snodgrass) urethroplasty in distal hypospadias repair.</p><p><b>METHODS</b>Between March 2001 and April 2004, Snodgrass-type repair was done in 36 patients and Mathieu-type repair in 43 patients with primary hypospadias either with or without minimal chordee.</p><p><b>RESULTS</b>The mean duration of surgery was significantly shorter for the Snodgrass procedure than for the Mathieu repair. With 3-10 months follow-up, the total numbers of complications of Snodgrass repair and Mathieu repair were 8 (22.2%) and 16 (37.2%) (P > 0.05), the fistula formation rates 8.3% and 25.6%, the meatal stricture formation rates 5.6% and 2.3%, and the wound dehiscence rates 8.3% and 2.3%, respectively. Flap necrosis was seen in 3 cases in the Mathieu group. Cosmetic appearance was highly satisfactory in the Snodgrass group.</p><p><b>CONCLUSION</b>The fistula and flap necrosis rates were lower and the surgery more convenient with the Snodgrass urethroplasty, which also had a better cosmetic outcome. The Snodgrass technique is recommended as a primary treatment to substitute Mathieu repair for distal hypospadias with or without minimal chordee.</p>
